Introduction

UniTrane™ fan coils are intended for single zone applications. These units have load capabilities of 200 to 1200 cfm. Fan coils provide cooling and heating, and are available as two-pipe, with or without electric heat (one hydronic circuit) or four-pipe (two hydronic circuits). These units feature a variety of factory mounted piping packages.

Units with the variable speed fan switch only, are available with the switch mounted on the unit, or shipped separately, to be mounted in the occupied space. The variable speed switch option, which ships separately, comes with a low voltage (24 volt AC) transformer.

The Tracer® ZN010, ZN510, ZN520, and UC400-B controllers are included inside the unit’s control box assembly. These controllers utilize analog signals from a unit-mounted control device or from a control device mounted in the occupied space.

The Customer Supplied Terminal Interface (CSTI) option, includes a 24 volt AC transformer, and an interface terminal board. Controls provided by an external source can be tied into the interface terminal board utilizing the integrated terminal block with 3mm screw connections.

Features and Benefits

The UniTrane™ fan coil meets the standards of today’s market, as well as the anticipated needs of tomorrow’s market. The UniTrane fan coil is the leader in these key areas:

• Energy Efficiency

• Indoor Air Quality (IAQ)

• Controls

• Flexibility

• Quality

• Serviceability

Today the HVAC market is concerned with issues such as indoor air quality (IAQ) and CFCs that demand a change in HVAC products. In addition, renovation has overtaken new construction in the fan coil market—demanding a design that caters to renovation issues. Trane is concerned with these issues, too. That is why we designed the UniTrane fan coil as an integral part of the company’s system solutions with standard IAQ-related features that fully comply with ASHRAE 62.

Energy Efficiency

Trane’s commitment to providing premium quality products has led to the exclusive use of Electronically Commutated Motors (ECM) in all fan coil models. These brushless DC motors incorporate the latest technology for optimized energy efficiency, acoustical abatement, maintenance free and extended motor life. Each motor has a built-in microprocessor that allows for programmability, soft ramp-up, better airflow control, and serial communication.

• Trane units equipped with ECMs are significantly more efficient than the standard permanent split capacitor (PSC) motor.

• Lower operating costs on average of 50 percent (versus a PSC motor).

• The reduced FLA feature allows units to ship with a nameplate FLA rating much lower than a typical unit.

IAQ Design

• Closed-cell insulation is standard on all units to help prevent fiberglass in the airstream.

• The main and auxiliary drain pans are constructed of a noncorrosive engineered plastic (ABS and CyColac T).

• The main and auxiliary drain pans are positively sloped in every plane to assure proper drainage and help maximize protection from microbial growth.

• The drain pans are removable for cleaning.

• Easy filter access encourages frequent changing.

• The auto-economizer damper option allows free cooling and ventilation to help comply with ASHRAE 62—and save energy and operating costs.

• UniTrane fan coils have a blow-thru design. Low vertical units are draw-thru.

Controls

• This is the industry’s first solution that is factory-mounted, -wired, and -programmed for infinite modulation of fan speed based on space loads, using the Tracer® UC400-B. Auto Fan Speed control with the Tracer® ZN520 ramps the fan speed up and down to meet space loads.

• All controls are factory-mounted and tested to minimize field setup and improve reliability.

• Controls are wired with a 24 Vac transformer to keep only a single source power connection requirement to the unit.

• All wall-mounted zone sensors require only low voltage control wiring from the device to the unit control box. (No line voltage.)

10 UNT-PRC001N-EN


• The controller automatically determines the unit’s correct operating mode (heat/cool) by utilizing a proportional/integral (PI) control algorithm to maintain the space temperature at the active setpoint, allowing total comfort control.

• Entering water temperature sampling eliminates the need for inefficient bleedlines to sense automatic changeover on two-pipe changeover units.

• The random start-up feature helps reduce electrical demand peaks by randomly staggering multiple units at start-up.

• Occupied/unoccupied operation allows the controller to utilize unoccupied temperature setpoints for energy savings.

• Warm-up and cool-down energy features are standard with Trane controls.

• Continuous fan or fan cycling is available with Tracer® ZN010 or ZN510.

• Monitor unit operation using Tracer® TU building management system with Tracer® ZN510 or ZN520 and UC400-B.

• To customize unit control, Tracer® TU or Rover™ software will allow field modification of Tracer® ZN510 and ZN520 default settings. Tracer® ZN010 uses Rover to field modify default settings. UC400-B uses Tracer® TU.

• Maximize fan coil system efficiency with free cooling economizers and modulating valves on units with Tracer® ZN520 and UC400-B.

Flexibility

• Two, three, and four-row coils allow greater design flexibility in two and four-pipe systems.

• One-row steam or hot water reheat coils for dehumidification on units with ZN520 controls.

• Fan motors are available for either high static (0.4-inch external static pressure) or free discharge applications.

• Piping is factory assembled, mounted and tested. Units are also available without piping. Reheat coil piping is available on 2-pipe units with hot water reheat coils and either a fan speed switch or Tracer® ZN520 and UC400-B.

• Control options range from a simple fan speed switch to a DDC controller that can tie into a Tracer® Summit building automation system.

• An 8-inch extended end pocket is available on the piping end of cabinet style units. An additional 8-inch extended end pocket is also available on the controls end of the cabinet style units.

• Slope-top vertical cabinet units are also available for school and dormitory applications to prevent items from being placed on top of the units.

Quality

• Coils and piping packages are air and leak-tested before mounting on the fan coil.

• Coil piping connections are also air and leak-tested after mounting on the unit.

• All control end devices and moving components (fans and motors) are computer-tested after units are complete.

UNT-PRC001N-EN 11


Serviceability

• Touch-safe control box.

• Integrated user interface with real language LED display.

• Built-in tachometer.

• Filters are easily removable and changed without removing the front panel on vertical cabinet units.

• Motors are easy to disconnect from the fan board, allowing easy service.

• The main and auxiliary drain pans are easily removable and wipe clean with a wet cloth.

• The manual output test function is an invaluable troubleshooting tool. By simply pressing the test button on the Tracer® ZN510, ZN520, or ZN010; service personnel can manually exercise outputs in a pre-defined sequence.

Components and Options

Motor and Control Board

• Trane Electronically Commutated Motor (ECM)

• VelociTach™ motor control board

The motor and control board are combined as a system, and cannot work without each other. This new series delivers outstanding comfort, safety, and performance with greatly reduced energy consumption compared to traditional units.

Electronically Commutated Motor (ECM)

VelociTach™ Motor Control Board

The VelociTach motor control board controls and reports the performance of up to two Trane brushless DC (BLDC) motors.

Status Display

• The ECM has integrated electronics, overload protection and short circuit protection. The motor contains no user-serviceable components inside.

• The motor mates to the unit electrically via a single plug that contains both the operating voltage and the control signals that are needed for correct operation.

The motor control board also:

• Coordinates the operation of the fan in response to electric heat behavior and electric behavior in response to hydronic heat behavior.

• Incorporates a user interface that allows adjustment of certain unit parameters and provides constant feedback on motor operation.

• Integrates service and troubleshooting tools.

• Integrates a versatile configurable auxiliary temperature sensor.

• Incorporates various safety and lockout features, such as maintaining proper fan speeds if electric heat is called for.

The motor control board contains a four-digit, seven-segment display that is used to present information in a format close to real-world language, while having a small-form factor. Most characters are immediately recognizable; however, please refer the following screen representation of alphabetical characters and numeric characters tables below.

UNT-PRC001N-EN 13


Factory-Installed Piping Packages

Standard piping packages are available as a factory-built and installed option. Piping package options are also available for the hot water reheat coil on two-pipe units equipped with either a fan speed switch or Tracer® ZN520 and UC400-B controller. Factory built assures all piping packages are fully tested under water for leaks and are built within strict tolerances. Factory-installed means that chilled and hot water pipes are the only field connections required. The installer doesn’t have to sweat connect piping packages onto coil connections in a tight end pocket. Field connections are brought to a point near the exterior of the unit for easy access. All piping and components are located to allow condensate to drain into the auxiliary drain pan. Insulation of the factory piping package is not required. However, all field connections should be insulated to prevent condensation from missing the auxiliary drain pan.

Piping Package Components

Control valves are mounted in all factory piping packages. All piping packages are factory installed and come in a variety of options:

• Basic: Shut-off ball valve on the supply line. Control valve and shut-off ball valve on the return line.

• Basic with Manual circuit setter: Shut-off ball valve on the supply line. Control valve and manual circuit setter on the return line.

• Deluxe with Manual circuit setter: Union, strainer, P/T port, and shut-off ball valve on the supply line. Union, control valve and manual circuit setter on the return line.

• Deluxe with auto flow: Union, strainer, P/T port, and shut-off ball valve on the supply line. Union, control valve, auto flow valve, P/T port and shut-off ball valve on the return line.

Piping System/Placement

Factory piping systems are available for either two or four-pipe systems with right or left hand connections. Four-pipe systems have both the heating and cooling connections on the same side of the unit. A simple coil connection (a unit without a piping package) is also available in either a right or left hand configuration for those applications requiring field piping.

Interconnecting Piping

Interconnecting piping refers to the copper piping which is attached to the coil connections and to which all other components (control valves, end valves, etc.) are attached. Piping is 1/2” nominal OD copper. Two-pipe piping extends near the unit exterior to one inlet and one outlet connection. Four-pipe units have two sets of piping that extend near the unit exterior — one inlet and one outlet each for both chilled and hot water. A label clearly identifies chilled and hot water connection points on every unit.

Why Trane Controls?

Trane offers a broad range of control packages from a field convertible end-device package, to a complete building automation system solution with BACnet® or LonTalk® controls.

The good news is Trane controls are factory-mounted, -wired, -tested and configured or programmed with Trane application expertise to provide comfort, efficiency, and reliability, as well as single-source warranty and service.WithTrane integrated controls, the installed costs are lower because the equipment has turn-key factory controls and every component of the system is optimized to fit with the controller.Trane installs not only the controller, but also the hardware that works intimately with the controller to allow the system to function properly (i.e., piping package, valves, dampers, actuators, etc.). When a product with Trane controls arrives on the jobsite, it is completely ready for quick installation.

Control Options

Available control options are:

• Fan speed control (provided when no control package is selected)

• Customer-supplied terminal interface (CSTI)

• Tracer® ZN010 controller



• Tracer® UC400-B controller with Air-Fi® Wireless Communications Interface

Fan Speed Control with Standard Adapter Board

Figure 14. Fan speed control The fan speed control is available for units that do not have Trane factory-mounted control packages. This variable fan speed option is low-voltage and has three 24-volt relays using a factory-wired transformer and relays to control the fan motor.

The adapter allows direct customer interfacing through the use of terminal strips. Standard interfacing includes variable speed (0–10V) inputs.

The standard adapter board eliminates many separate wiring harnesses in the panel and allows simple, mistake-proofed single-plug interfacing of:

• VelociTach™ motor control board

• Transformers

• Motors

• Valves

• Dampers

• Electric heat control

• Fan speed control

Customer Supplied Terminal Interface (CSTI)

The CSTI is intended to be used with a field-supplied, low-voltage thermostat or controller. The control box contains a relay board which includes a line voltage to 24-volt transformer and disconnect switch (for non-electric heat units). All end devices are wired to a low-voltage terminal block and are run-tested, so the only a power connection and thermostat connection is needed to commission the unit. Changeover sensors and controls are provided whenever a change-over coil is selected. When N.O. valves are selected, inverting relays are provided for use with standard thermostats.

The CSTI adapter board provides all the hookups as the standard adapter board, but in addition, provides hookups for valve control (main and auxiliary coils), electric heat control, and damper control. Screw terminal blocks provide convenient access to fan controls and to end device control. In addition, a courtesy 10 VDC supply is provided for use with an external potentiometer or rheostat. The 10 VDC supply supports up to 10 mA draw.

Tracer® Controllers

Tracer® ZN010 controller is a stand-alone microprocessor controller.

Tracer® ZN510 controller can be used as either a stand-alone or communicating microprocessor controller.

Tracer® ZN520 Controller

The Tracer® ZN520 controller is a factory-installed, -tested and -commissioned LonTalk® control designed to provide control of Trane products. Features include:

• Automatic fan-speed reset

• Automatic ventilation reset

• Active dehumidification

• Manual output test

• Filter maintenance

• Master slave

• Water valve override

• Freeze avoidance

• Interoperability

• Three generic I/O ports

The Tracer® ZN520 controller is designed to be used in the following applications:

• As part of a Tracer® SC or Tracer® Summit building automation system (BAS), the Tracer® ZN520 becomes an important part of the Tracer® control system.

• The Tracer® ZN520 can function as a completely stand-alone controller in situations where a BAS is not present.

• For situations when a non-Trane BAS is present, the Tracer® ZN520 can be used as an inter-operable unit controller.

Through building management of the HVAC system, optimizing energy consumption becomes possible at the room level. Each unit is capable of functioning independently of one another during occupied and unoccupied hours of the day. This allows the temperature setpoint and ventilation setting to be changed automatically based on usage.

Two Systems in One

In a Tracer® system environment, the Tracer® ZN520 is pre-designed to install quickly and easily into the system. Since the controller and the unit are factory tested and commissioned, the start-up time for the entire system is minimized. Trane becomes the single source of responsibility for the equipment, unit controls, and building automation system.

As a standalone controller, the Tracer® ZN520 is ideally suited for fix-on-fail replacement of units with old pneumatic controllers, or in situations where a BAS will be added at a later date. Once power is applied to the controller, it will automatically start up and run based upon the setpoint on the local zone sensor. An individual time clock can be added to the unit for local scheduling.

The Tracer® ZN520 is certified to the interoperable LONMARK® Space Comfort Controller profile. This allows the controller to be used with another vendor BAS and thereby still provide the high quality of factory installation and testing. In addition, the Tracer® ZN520 provides one of the most extensive interoperable data lists of any controller of its type in the industry.

Tracer® UC400-B Controller

The Tracer® UC400-B single-zone VAV controller can be used in a stand-alone application or as part of a Tracer® control system.

In the stand-alone configuration, Tracer® UC400-B receives operation commands from the zone sensor and/or the auto changeover sensor (on auto changeover units).The entering water temperature is read from the auto changeover sensor and determines if the unit is capable of cooling or heating. The zone sensor module is capable of transmitting the following information to the controller:

• Timed override on/cancel request

• Zone setpoint

• Current zone temperature

• Fan mode selection (off-auto-high-med-low)

For optimal system performance, units can operate as part of a Tracer® SC building automation system. The controller is linked directly to the Tracer® SC via a twisted pair communication wire, requiring no additional interface device (i.e., a command unit). The Tracer® control system can monitor or override Tracer® UC400-B control points.This includes such points as temperature and output positions.

Tracer® Controller Features

The Tracer® family of controllers, ZN010, ZN510, ZN520, and UC400-B offer the combined advantages of simple and dependable operation with the latest Trane-designed controller. Standard control features include options normally available on more elaborate control systems. All control options are available factory-configured or can be field-configured using Rover or Tracer® TU service software. For more detailed information, refer to Trane installation manuals CNT-IOP-1 (for Tracer® ZN010 or ZN510), CNT-SVX04*-EN (for Tracer® ZN520), or BAS-SVX48*-EN (for Tracer® UC400-B).

Features Available on All Controllers

The following control functions are standard features on units with Tracer® ZN010, ZN510, ZN520, or Tracer® UC400-B.

Entering Water Temperature Sampling Function

A system that uses a two-way control valve option might not sense the correct entering water temperature during long periods when the control valve is closed. If the demand for heating or cooling does not exist for a long period, the entering water will eventually approach ambient temperature.

Using the entering water temperature sampling function, the controller provides accurate two-pipe system changeover-without sacrificing the benefits of two-way control valves. Also, it eliminates inefficient bleed or bypass lines that can allow unnecessary waterflow through the system.

This function periodically samples the entering water temperature by opening the hydronic valve. The valve opens for 20 seconds to allow the water temperature to stabilize.Then the controller reads the entering water temperature for up to three minutes to see if the correct water temperature is available for the selected operating mode.

The entering water temperature must be five degrees or more above the space temperature to allow hydronic heating and five degrees or more below the space temperature to allow hydronic cooling. If the correct water temperature for the operating mode is available, the unit begins normal heating or cooling operation. If the correct water temperature is not available, the controller closes the control valve and waits 60 minutes before attempting to sample the entering water temperature again.

A factory-mounted thermistor senses the entering water temperature on changeover cooling/ heating coil units. If the fan coil has a factory-mounted piping package, the sensor is strapped to the entering water pipe. If the fan coil does not have a piping package, the sensor is coiled in the end pocket for mounting on customer-supplied piping.This sensor must detect accurate water temperature for proper changeover.

Automatic Heat/Cool Mode Determination

The controller automatically determines whether heating or cooling is needed-based on space and system conditions. Using a proportional/integral (PI) control algorithm to maintain the space temperature at the active heating or cooling setpoint.The controller measures the space temperature and active setpoint temperature to determine the unit's heating or cooling capacity (zero to 100 percent).

Occupied/Unoccupied Operation

The occupancy input uses a binary switch (i.e., motion sensor, time clock, etc.) that allows the zone sensor to use its unoccupied internal setpoints.

Random Start

This feature randomly staggers multiple unit start-up to reduce electrical demand spikes.

Warm-up

The two-position fresh air damper option closes during the occupied mode when the space temperature is three degrees or more below the heating setpoint temperature.The damper remains closed during warm-up until the space temperature is within two degrees of the heating setpoint temperature.

Cool-down

The two-position fresh air damper option closes during the occupied mode when the space temperature is three degrees or more above the cooling setpoint temperature.The damper remains closed during cool-down until the space temperature is within two degrees of the cooling setpoint temperature.

Manual Output Test

This function may be initiated from the blue test push button on the controller or through the Rover or Tracer® TU service tool.This feature is used to manually exercise the outputs in a defined sequence.

The purpose of this test sequence is to verify output and end device operation.The manual output test function may also be used in the following situations:

• Reset latching diagnostics

• Verify output wiring and operation

• Force the water valve(s) open to balance the hydronic system during installation set-up or service.

Peer-to-Peer Communication (Tracer® ZN510, ZN520, and UC400-B)

Peer-to-peer communication allows multiple units in one space to share the same zone sensor and provide simultaneous heating and cooling.TheTracer® ZN510 or ZN520 controller can share information between units on the same communication link using a twisted pair wire in the field. Unit configuration must be modified with Rover service tool. On the Tracer® UC400-B, zone sensor data sharing can be accomplished by use of the BAS system controller.

A thermistor to sense fresh air is factory-mounted at the unit's fresh air opening for use in economizer applications or as a read-only point for Tracer® SC or Tracer® Summit. If the fresh air temperature is a read-only value, it will not impact the control algorithm. In an economizer application, a fresh air temperature signal must be provided either by this thermistor, Tracer® SC, or Tracer® Summit.

Controls

Additional Features

Single Zone VAV with Fully Modulating Fan Speed (Tracer® UC400-B)

The Tracer® UC400-B will minimize fan speed, and in turn energy usage, by only delivering the air flow needed.

Economizing Control (Tracer® ZN520)

With the controller configured for economizing control, it will calculate the required cooling capacity every ten seconds and modulate the damper option open to the calculated position. If the setpoint is not satisfied, the damper will continue to open until the setpoint condition has been met or the damper is 100 percent open. If this still does not satisfy the setpoint, the cooling valve option will begin to open and try to satisfy the load requirements. Once capacity exceeds the load requirements, the valve will begin to close until the setpoint has been reached or the damper reaches its minimum position, which is field-adjustable.This option uses a three-wire, floating point damper actuator.

A thermistor to sense discharge air is factory mounted near the discharge surface of the last coil for use in economizing and cascade temperature control.Tracer® SC or Tracer® Summit can also use this temperature value as a read-only point. Cascade temperature control uses both the zone and discharge air temperatures to more accurately calculate the required unit capacity.

Automatic Fan and Ventilation Reset

A two-speed fan control for the unit delivers the airflow output customized to support the cfm space needs.When less cfm is necessary to meet the load of the classroom (typically 75 to 80 percent of the time), the equipment operates on low speed. However, if the room temperature rises, the controller will switch to high speed, and the outside air damper will adjust to satisfy the space needs.This helps maintain the proper amount of ventilation air to the occupants independent of the fan speed. As part of the ventilation strategy, the controller will reposition the outside air damper to confirm the minimum outside air cfm is met at both operating conditions.

Filter Maintenance

Filter status for the controller is based on the cumulative run hours of the unit fan. The controller compares the amount of fan run time against an adjustable fan run hour (stored in the controller) to determine when maintenance is recommended for the unit. The run-hours value may be user edited as required (through Rover or Tracer® TU). The valid range for the fan run hours limit is 0 to 5000 hours with a default of 600 hours. Once the run hours limit has been exceeded, the

controller generates a maintenance required diagnostic (unit will not shut-down). The user will be notified of this diagnostic through the building automation system or when a Trane service tool is communicating with the controller.

Active Dehumidification

On units with reheat coils, the controller can provide active dehumidification. This means that the relative humidity in the space can be kept below an adjustable setpoint independent of outdoor weather conditions. Indoor humidity levels are recommended by ASHRAE to be kept below 60 percent in order to minimize microbial growth and the life span of airborne illness causing germs.

Master Slave (Data Sharing)

The controller can send or receive data (setpoint, heat/cool mode, fan request, space temperature, etc.) to and from other controllers on the communication link with or without the existence of a building automation system. This applies to applications where multiple units might share one zone sensor for both stand-alone (with communication wiring between units) and a building automation system.

Water Valve Override

The controller can be commanded via the Rover service tool or Tracer® TU to open all hydronic valves 100 percent. This allows for the faster water balancing of each unit and the entire system when the command is sent globally to all controllers. A properly balanced system is essential for proper and efficient operation.

Hydronic Coil Freeze Protection (Freeze Avoidance)

Systems in cold climates need to take precautions to avoid hydronic coil freeze-up. The controller does this from three different aspects. Any of these methods of protections will result in the unit fan being disabled, the outside air damper being shut, and the hydronic valves being opened 100 percent.

The three methods of freeze avoidance include:

1. A binary freeze protection thermostat is mounted on the coil and will cause a latching diagnostic if the coil temperature falls below 35°F.

2. An analog discharge air sensor monitors the temperature of the air coming off of the coil and if the temperature falls below 40°F the outside air damper is closed, the fan is turned off and the valves are fully opened.

3. When in the unoccupied mode, the controller has an adjustable freeze avoidance setpoint. If the outside air temperature is below the setpoint, the unit will open the valves to allow water to flow through the coils.

Interoperability

Inter-operability allows the owner freedom to select multiple vendors, and multiple products. With this advantage, the owner can choose the best products, the best application, and the best service from a variety of suppliers to meet their evolving building control needs in a cost effective manner.

Generic Binary Input/Output

The three generic binary inputs/outputs are not part of the normal control, but are actually controlled through the Tracer® SC or Tracer® Summit system (when present) to issue commands to the controller to turn the generic inputs/outputs of add-on equipment (such as baseboard heating, exhaust fans, occupancy sensors, lighting, etc.) on and off. This binary port is not affected when other binary diagnostics interrupt unit operation.

Tracer® Controls Sequence of Operation

Fan Speed Control

A fan speed control is supplied on units with fan control or CSTI options. It provides variable speed of the motor RPM between the low and high speed factory settings.

Tracer® ZN010 and ZN510

Off: Fan is off; control valves and the low air temperature detection option are still active.

Auto (Fan Cycling): The fan and mixing box damper cycle with control valve option to maintain setpoint temperature. If the unit has three-speeds, in cooling mode the fan cycles from off to high and in heating mode it cycles from off to low (factory default that can be field-adjusted using Rover service software). When no heating or cooling is required, the fan is off and the mixing box damper option closes. Units with three speeds can also be field-configured using Rover to run at a defined speed when the fan speed control is in the auto position.

Low, Medium, or High (Continuous Fan): The fan operates continuously while control valve option cycles to maintain setpoint temperature. The mixing damper option is open.

Tracer® ZN520 and UC400-B

Off: Fan is off; control valve options and mixing box damper options close. The low air temperature detection option is still active.

Auto: Fan speed control in the auto setting allows the modulating control valve option and single- or three-speed fan to work cooperatively to meet precise capacity requirements, while minimizing fan speed (motor/energy/acoustics) and valve position (pump energy/chilled water reset). As the capacity requirement increases at low fan speed, the water valve opens. When the low fan speed capacity switch point is reached, the fan switches to the next higher speed and the water valve repositions to maintain an equivalent capacity. The reverse sequence takes place with a decrease in required capacity.

Units with three-speed fans on low, medium, or high: The fan runs continuously at the selected speed and the valve option cycles to meet setpoint.

Figure 30. Economizer fresh air damper actuator

This option is a three-wire floating point, spring-return damper actuator and is factory-wired and mounted to the damper assembly. When the controller enables the economizer and the unit is in occupied mode, the fresh air damper modulates between its minimum position (editable) and the full open position to maintain setpoint temperature. If economizer operation stops or if the unit is in the heating mode, the fresh air damper adjusts to its minimum position.

Note: Trane highly recommends using the low temperature detection option with a fresh air damper to detect possible freeze conditions.

Figure 31. Low temperature detection device

When the low temperature detection device senses an entering air temperature of 36°F to the hydronic coil, the normally-closed switch opens a corresponding set of binary input terminals. The fan disables, control valves open, and the fresh air damper closes.

Thirty minutes after the diagnostic, Tracer® ZN010, ZN510, or ZN520 uses an automatic reset function to attempt to reset the unit. If the diagnostic occurs again within 24 hours after an automatic diagnostic reset, the unit will require a manual reset. This function attempts to resolve the infrequent nuisance alarm.

The low temperature detection device is an averaging type capillary tube and will reset when it detects an entering air temperature of at least 44°F.

Figure 32. Condensate overflow detection device

A float switch is factory-supplied for field installation in the auxiliary drain pan to detect a high condensate water level. When the float switch rises, the normally closed input opens a corresponding set of binary input terminals. With Trane controls installed, this also causes the fan to disable, and the control valve and fresh air damper options to close. Although the float switch will close when the high condensate level recedes, the controller must be manually reset before normal unit operation can occur. If using a Tracer® ZN510, ZN520 or UC400-B controller you can reset using Tracer® Summit. Use Rover service software to reset units with Tracer® ZN010, ZN510, or ZN520 and Tracer® TU for units with a UC400-B. When wired to the CSTI, the switch does not de-energize the unit when open position occurs. This is a dry contact only and sequence of operation of unit when this condition is reached is the responsibility of the field provided controller or thermostat.

Controls

Frostat™ Temperature Switch

Outside Air Sensor

The outside air sensor is field-mounted to sense the outside air temperature, primarily for use in economizer applications or as a status value when available for other applications.

Control Valves

Three-way valve options allow either full waterflow through the coil or diverted waterflow through the bypass.

Two-Position Control Valves

Two-position valves are capacitor discharge return. Capacitor discharge valves respond to a 24 V signal and will either fully open or close. These valves cannot be driven or actuated to a partially open or closed position. If the capacitor discharge return type control valve loses power, the valve returns to its de-energized position.

Modulating and 2-10 V Analog Control Valves

Modulating and 2-10 V Analog control valves offer an alternative for more precise capacity control by modulating or varying the water flow through the coil. Modulating valves respond to a 24 V signal from the controller, which determines the valve position by a control algorithm. Analog valves travel to the commanded position of the 2-10 V control signal. If the valve loses power, it remains in the position it was in when the power loss occurred.

Field-Supplied Valves

This option allows the controller to be factory-configured for a field-supplied valve, as well as a wire harnesses running from the control box to the piping side of the unit. When the field-supplied valve option is chosen, the control box is provided with low voltage components and wired back to a terminal strip (CSTI) or controller.

Note: Trane does not recommend wild coil applications.

Figure 33. Frostat™ temperature switch

When the Frostat switch senses a coil temperature of 39° F, the Frostat switch will open and the DX signal to the condenser will be interrupted. This turns off the compressor. The fan coil will continue to operate, allowing the coil to reach a temperature of 55°F. When the coil reaches 55°F, the Frostat will close allowing normal DX operation.

Units with either the control interface or any of the Tracer® controllers (Tracer® ZN010, ZN510, ZN520, or UC400-B) are available with chilled and/or hot water control valves for each coil configuration. Control valve options are available as:

• Analog (2-10 VDC)

• Modulating

• Two-position, normally-open (n.o.) or normally-closed (n.c.)

• Two- or three-way configurations

• With sweat connections

Selecting the Correct Modulating Valve Size

The coefficient of flow is defined as the volume of water flow through a control valve in the fully open position with a 1 psig differential across the valve. It is calculated using the following formula:

Cv = Q/Square root ΔP where:

Cv = flow coefficient

Q = flow rate (gpm)

ΔP = pressure drop across the valve or coil (psig).

For good control, the valve Cv should be approximately equal to the Cv of the water coil.

Modulating Valve Selection Example

Assume a size 06 fan-coil is selected to operate at the following conditions:

Vertical Cabinet Fan Coil

Entering water temperature = 45°F

Leaving water temperature = 55°F

EAT conditions = 80/67

The coil is selected as a four-row coil.

Select the best modulating valve size for this unit.

1. Find the ΔP across the water coil. Refer to the AHRI performance table to determine the ΔP across the water coil (or use TOPSS™ selection program). The water pressure drop is found to be 7.0’ of water at a flow rate of 3.74 gpm. This converts to a pressure drop of 3.03 psig (1.0 feet of water = 0.4328 psig.)

2. Calculate the Cv of the water coil. Cv = GPM/Square root ΔP Cv = 3.74/Square root 3.03 Cv = 2.15 Therefore, the valve with the Cv of 2.4 should be selected since it has the Cv which is closest to the Cv of the water coil. The following tables illustrate possible valve selections at AHRI conditions for horizontal concealed units with a high static motor and vertical cabinet units with a free discharge motor.

UNT-PRC001N-EN 123


control box with a built-in integrated user interface and LED tachometer. If adjustments are needed, motor parameters can be adjusted through momentary contact switches accessible without factory service personnel on the motor control board.

Motors will soft-ramp between speeds to lessen the acoustics due to sudden speed changes. Motors can be operated at three speeds or with a field-supplied variable speed controller. The motor will choose the highest speed if there are simultaneous/conflicting speed requests.

All motors have integral thermal overload protection with a maximum ambient operating temperature of 104°F and are permanently lubricated. Motors are capable of starting at 50 percent of rated voltage and operating at 90 percent of rated voltage on all speed settings. Motors can operate up to 10 percent over voltage.

Extended End Pockets

On vertical or horizontal cabinet units, an 8-inch extended end pocket is available on the piping end. On vertical cabinet and vertical slope top units, an 8-inch extended end pocket is available on both the piping and control side.

Tamperproof Locks

Key-operated locking access doors and/or panels will help prevent nuisance tampering with unit and/or controls. Tamper proof locks are available on vertical cabinet, horizontal cabinet, vertical recessed, vertical slope top, and low vertical units.

Leveling Feet

Refrigerator type screw-in bolts to level the unit are available on vertical and low vertical cabinet units.

Controls

Controls options are: fan speed control, customer supplied terminal interface, and Tracer® ZN010, ZN510, ZN520, and UC400-B. A variety of inputs and outputs are available for the control interface and Tracer® controller options. A disconnect switch (for non-electric heat units), fused transformer, contactor(s), and terminal strip are provided with the control interface and Tracer® controller options.

Customer Supplied Terminal Interface

The control interface is intended to be used with a field-supplied, low-voltage thermostat or controller. The control box contains a relay board which includes a line voltage to 24-volt transformer, quiet contactors (for electric heat units), and an optional disconnect switch. All end devices are wired to a low-voltage terminal block and are run-tested, so the only a power connection and thermostat connection is needed to commission the unit. Changeover sensors and controls are provided whenever a change-over coil is selected. When N.O. valves are selected, inverting relays are provided for use with standard thermostats.

Fan Speed Control

The fan speed control is available with or without the control interface option and is available as wall-mount or unit-mount. The speed control incorporates a 0-10 VDC signal providing limitless control of the motor RPM between the factory set low and high speeds. The control box contains a line voltage to 24-volt transformer, ECM motor controller, and an optional disconnect switch.

Disconnect Switch

A unit mounted disconnect switch is available as a standard option on all units.

124 UNT-PRC001N-EN


Coils

All water coils are proof-tested at 300 psig (air) and leak-tested at 100 psig (air under water). Maximum main coil working pressure is 300 psig. Maximum entering water temperature is 200°F. Tubes and u-bends are 3/8-inch OD copper. Fins are aluminum and are mechanically bonded to the copper tubes. Coil stub-outs are 5/8-inch OD copper tubing.

Reheat Coils

Reheat coils are available for use with both hot water and steam. Hot water maximum working pressure is 300 psig, and the maximum entering water temperature is 200°F. The steam coil maximum working pressure is 15 psig. The reheat coils are constructed of single circuit 5/8-inch copper tubes with aluminum fins. Piping connections are expanded to accept standard copper tubing 5/8-inch OD.

Electric Heat Coil

The auxiliary electric heating coil is provided as either the total source of heat or auxiliary intermediate season heating. The electric heat coils are located in the preheat position, and are the open-wire type. The coils are a nickel chromium element design. The electric heat operates at the same voltage as the unit, and only a single power connection is necessary.

All units with factory-mounted electric heat are UL-listed and interlocked with the fan motor switch. A call for electric heat operation will turn the fan on. Motors controls are synchronized with fan/valve operation to ensure safe operation and to ensure that two modes of heat are not operating simultaneously. A transformer is supplied on any voltage unit, eliminating the need for field installation of a step-down transformer. Unit-mounted quiet magnetic relays are supplied on all voltages. A high temperature cutout with automatic reset is provided as an integral part of the elements to de-energize the electric heat in the event of a malfunction.

Figure 56. Sub-base (shown turned on its side)

Sub-bases elevate vertical cabinet or slope top cabinet units to a specified height; for example, to reach the bottom of a window sill. The sub-base also provides a cavity through which to run piping underneath the fan coil unit. Sub-bases are 16-gauge steel construction and have the same black paint finish as the base of the unit. The sub-base is available in heights between two inches and seven inches in 1/2-inch increments. The sub-base depth and width is identical to the dimensions of the unit.

Figure 57. False backs

False backs increase the depth of a vertical cabinet unit and provide a cavity through which to run piping behind the fan coil unit. False backs are also an excellent application when installing a unit beneath a window sill that extends out past the front of the unit.

False backs are 18-gauge steel construction and have the same paint finish as the unit. The false back is available in depths between two inches and eight inches in 1-inch increments, with height and width identical to the dimensions of the unit.

Figure 58. Recessing flanges

Recessing flanges have 18-gauge steel construction and are painted the same finish as the unit. Recessing flanges provide an aesthetic architectural border or frame around vertical and horizontal cabinet fan coil units.

Figure 59. Wall box

Wall boxes have a clear anodized finish and include a single core wire mesh insect screen. The frame is 10-gauge extruded aluminum alloy 6063-T5 construction. Horizontal louvers have 16-gauge extruded aluminum alloy 6063-T5 construction.

Wall boxes ship separate for field installation. A field supplied duct or sleeve from the wall box to the unit fresh air opening is required to provide fresh air. Wall boxes are sized to handle up to 100 percent of nominal air flow.

Projection Panels

Piping Package

All piping packages are proof-tested at 300 psig (air) and leak tested at 100 (air under water.) The maximum working pressure of the interconnecting piping is 300 psig.

The piping package is designed so that any condensation is directed into the UniTrane auxiliary drain pan. Insulation of piping package is not required.

Control valves are mounted in all factory piping packages. All piping packages are factory-installed and come in a variety of options:

• Basic: Shut-off ball valve on the supply line. Control valve and shut-off ball valve on the return line.

• Basic with manual circuit setter: Shut-off ball valve on the supply line. Control valve and manual circuit setter on the return line.

• Deluxe with manual circuit setter: Union, strainer, P/T port, and shut-off ball valve on the supply line. Union, control valve and manual circuit setter on the return line.

• Deluxe with auto flow: Union, strainer, P/T port, and shut-off ball valve on the supply line. Union, control valve, auto flow valve, P/T port and shut-off ball valve on the return line.

Two Position Control Valves

Two position control valves are ball valve designed with zero leakage. The ball valve incorporates self-cleaning technology to provide superior clog resistance. The actuator is easily removable for service without removing the valve body. Actuators are capacitor discharge return.

Modulating and Analog (2-10 VDC) Control Valves

Modulating and analog control valves are ball valve designed with zero leakage. The ball valve incorporates self-cleaning technology to provide superior clog resistance. If the actuators fail, they can be easily removed for servicing without removing the valve body.

Figure 60. Projection panel

Projection panels allow semi-recessing of vertical recessed units.

Panels are 16-gauge steel construction, painted with a baked powder finish. They are available in projection depths ranging from two inches to six inches in 1/2-inch increments. There is a distance of 7/8 inch between the projection panel and the front of the unit.

End Valves

Each piping package includes a ball valve on the entering water pipe and one of the following end valve on the leaving water pipe:

• Ball valve

• Manual circuit setter

• Auto circuit setter

End valve serves as the field connection points on all the Fan Coil piping packages.

Ball Valve

Ball valves, also known as stop valves, allow the unit to be cut off for service purposes. These valves have a two inch handle that rotates 90 degree to a fully open position.

Manual Circuit Setter

A manual circuit setter acts as both a flow setting device and a stop valve. This valve allows water flow through the unit to be set quickly and accurately. The manual circuit setter includes ¼ in. Schrader ports in the valve body. These ports are used to measure the pressure drop across the valve. This pressure drop can be compared to factory supplied curves that relate the pressure drop to a specific flow rate. This valve also has a memory stop that helps find the correct setting quickly.
