Energon - Fan Coil Digital Controller NR9000/NR9000-RT

1st Issue 09/13 1 DBL408e

APPLICATION AND USENR9000 is a digital controller for 2- or 4-pipe terminal units (eg. Fan Coil) with ON/OFF, 3-POINT floating or modulating con-trol valves as well as with 3-speed or modulating fan. NR9000 is equipped with MODBUS (SLAVE) communication protocol enabling the communication with other MODBUS devices (MA-STER). NR9000 is composed by a M6 DIN-BAR unit and a flush mounting remote terminal (NR9000-RT) with integrated room terminal sensor.NR9000 and NR9000-RT do not have internal clock manage-ment. Time schedule must be programmed by a supervisory system.TECHNICAL CHARACTERISTICSPower supply: 85-265Vac (isolated)Protection Degree: IP 20Operation temperature: 2T 45 °CStorage temperature: -25T 65 °CDimensions (mm): DIN M6Inputs:• Digital Input Window Contact.• Digital Input Remote Power off.• Digital Input Winter/Summer Change Over. • Digital Input Comfort/Economy.• Analog Input Return Temperature Sensor.*• Analog Input Remote Temperature Set.*• Analog Input (S3) Auxiliary loop sensor• Analog Input (S4) Auxiliary loop set selector

“Remote Power off” or “Comfort/Economy” digital inputs can be used to interface the controller with a Presence Detector to mi-nimize costs for heating and cooling.When digital inputs are in use they have priority on remote sen-sor and supervisory system.

* Sensors with a sensing element NTC10K Ohm @ 25°C. Accuracy ± 1K, β @ 25°C = 3435 (reference controlli room sensors S4xxA/B and SNTC-xL)

Digital inputs can be enabled using a configuration tool called “Configuratore NR9000” thanks to which you can also reverse the inputs action. It can be downloaded by our web site www.controlli.eu.The default status of digital inputs (factory setting) is the fol-lowing:

DIGITAL INPUT DEFAULT DESCRIPTION

WINDOW CONTACT N.C (normally closed) OPEN – window opened CLOSE – window closed

REMOTE POWER OFF N.O (normally open) OPEN – Comfort CLOSE – off (frost protection)

WINTER/SUMMER CHANGEOVER N.O (normally open) OPEN – winter

CLOSE – summer

COMFORT/ECONOMY N.O (normally open) OPEN – Comfort CLOSE – economy

For example, in case the window switch is normally opened (closed window is equivalent to open contact) it is necessary to reverse the action of the digital input.Outputs:• 4 TRIAC Outputs to drive 3P valves (HOT valve and COOL

valve). Contact Rating 24..250V 4 A;

• 3 RELAY Outputs to drive 3 speed FAN (V1, V2, V3). Con-tact Rating 24..250V 8 A;

• 2 Analog Output 0-10V to drive proportional valves. It is possible to use 0-10V outputs to drive a modulating FAN plus modulating valves in sequence (0-5/6-10).

• 2 Open Collector Outputs: OC1 and OC2. They have a ma-ximum load of 18mA and can be used to drive 12Vdc relays whose maximum power is 220mW and winding resistance >= 640Ohm (ref. Controlli relay module mod. DGSRMV).• OC1 output follows the ON/OFF input and it can be

used, through an external relay, to enable electrical loads. If the local operation mode is enabled (through controller password) OC1 follows the input DI2 (over-ride turn off), so if DI2 is open, OC1 is ON too, instead if DI2 input is closed, OC1 is OFF too. If the local ope-ration mode is disabled, OC1 follows the value set at 9011 ModBus address.

• OC2 output is used to enable auxiliary functions de-scribed in the “Controller functions” paragraph. If the temperture sensor S3 is present, the ON/OFF auxilia-ry loop which controls OC2 will be automatically ena-bled; otherwise it is possible to enable the electrical coil in emergency (through controller password) wich controls OC2. If the sensor S3 is not present, OC2 follows the value set at 9013 ModBus address.

• Bus to connect Remote Terminal NR9000-RT.• Bus Modbus to connect Supervisor System.• Bus Link to connect IO expansion.

OPERATIONThe internally stored parameters used by the controller during operation can be changed using NR9000-RT Remote Sensor or using a Supervisory System (MODBUS protocol). Remote Sensor NR9000-RT allows to change the operation mode, the set point and the fan speed; all other parameters can be modi-fied only through the supervisory system or the dedicated con-figuration tool. The controller can operate also without the Re-mote Sensor using a dedicated analog input (Return Sensor).

The controller will take the data coming from the Sensor and from the Supervisory system (if present) and will perform a P or PI or PID regulation to drive the valves and the fan.

The controller can operate also without NR9000-RT and su-pervisory system (Modbus). In this case the room temperatu-re is measured by the return sensor and thanks to the remote selector is possible to set the correction of the temperature. In this configuration, the control parameters can be changed only through a dedicated configuration tool.System configurationThe system can be configured as shown in the following dia-grams:

• Controller + Remote Sensor

ROOM 1

• Controller (Stand Alone)

ROOM 1

Return Sensor

• N Controllers + 1 Remote SensorN max expansions = 6In this configuration all the controllers will communicate with the controller connected to the remote sensor using LINK bus. All the controllers will operate in the same way (IO expansion).

Supervisory systemThe supervisory system can be implemented using the fol-lowing MODBUS-RTU (master) devices: • Operator Panel: MT-NET-PONR: it is possible to connect

up to 50 controllers.• PC Supervisor: Micronet View or the configuration tool

“Configuratore NR9000” downloadable from www.control-li.eu site.

• Touch Screen GT series: it is possibile to connect up to 48 controllers

ModBus - RS485 ConnectionThe RS485 network is implemented with a 3-conductor cable, which will be later identified as “+” (pin 23), “-” (pin 24) and “GND” (pin 25). For wiring is suggested Belden ®, model 8762.For “disturbed” areas is suggested a Belden ®, model 3106A using the twisted pair to connect the “+” and “-“, the reference wire to connect to “GND” and the shield to connect to ground.

Alternatively you can use a cable with the following electrical and mechanical characteristics:

• AWG 20/22;• characteristic impedance of 120Ω;• copper wire, “plait” type, twisted;• shielded braided and insulated;

The shield must be connected to controller GND (pin 25).


ISO 9001

The network must be wired only in accordance with the principle shown here, called “daisy chain” (the device is composed by a sin-gle RS485 port). Star connections are not allowed.

Connection warningsFor proper network cabling is recommended to take the fol-lowing precautions:

1. NOT use different types of cable to achieve the same net-work, but always use only the same type of cable;

2. The network cable carries out safety voltage signals (SELV) and must not be wired together with dangerous vol-tage signals (eg 230V) or carriers of high currents, espe-cially if in alternating current. Also avoid parallel paths to these power cables;

3. Wire the cable lying avoiding kinks, narrow bending radii and unnecessary wrapping in hanks or skeins;

4. Do not twist the cable cord around the power conductors and, if they should cross, consider an intersection at 90 ° between the cable and these conductors;

5. Keep away from sources of electromagnetic field in parti-cular by large motors, electrical cabinet, reactors for neon, all types of antennas;

6. Do not pull the power cable exceeds 110 N (11.3 kg) to prevent ironing;

7. Assess in advance the route so that it will be as short as possible and note addresses of connected instruments with particular reference to its location in the orderly sequence. This can be very useful in maintenance; we recommend to note the Modbus Address on the product label.

Terminating transistors and network polarizationThe slew rate control, mutual function in our 485 transceiver and the limited baud rate to 9600 baud make the terminating resistors not necessary.RS485 network needs of polarization typically in charge of the master device; the controller doesn’t have polarization resistors.

The tranceiver used by the controller allows to drive up to 256 points. RS485 standards require a maximum length of 1200 m and / or 32 devices on the network.It should be noted that more limits are exceeded, higher is the probability that problems in communication arise. The pheno-menon is not systematic and may not occur. Conversely, in case you present, and none of the points mentioned in this pa-ragraph has solved the problem, it is recommended to connect a repeater (CONV RS485-RIP), as shown in the pictures below:

• Repeater placed where the network exceeds 1200m

• Repeater placed where the network exceeds 32 devices

8. Do not reverse the polarity “+” and “-” of the connection terminals;

9. Avoid short lengths of cable terminations in connection to-ols to make a maintenance without tearing or flues of the cables possible;

10. Identify start and ending terminations and avoid cuts “open”;


ISO 9001

Electrical Coil in “emergency” mode:

Operation modesNR9000 works with 3 different operation modes:

• COMFORT: the controller will control the temperature (dri-ving valves and fan) to satisfy the Comfort Temperature Set.

• ECONOMY: the controller will control the temperature to satisfy the Economy Temperature Set.

• FROST PROTECTION: the controller is normally OFF; just during winter operation it works with a set fixed at 8°C and heating function only.

FUNCTIONS

Summer/Winter ChangeoverThe summer / winter changeover is used by the controller to reverse the action (Hot / Cold) in 2-pipe systems and to de-termine whether to add or subtract the temperature correction in Economy mode. This information can be defined through a dedicated digital input or via parameter and it can be set by the supervisory system or by a configuration tool using MODBUS protocol.N.B: by default Summer/Winter changeover is set by remote mode; in stand alone plants it has to be preconfigured in local mode; Initial Valve positionTo drive a 3-point actuator is necessary to place the actuator in a specific position.Each time the controller is powered up, the actuator will be dri-ven in the closing position for a time equal to the overall travel time plus 33%.

Cut-offThis function is used to stop the control of the 3 points actuator after the overall travel time plus 33%. This function is used to ensure the correct valve closing and to reduce the noise.

Window contactThis function is used to save energy when a Normally Closed contact is opened (Open Window). In this case the controller will change the operation mode from Comfort to Economy.

Hot/Cold launchThis function is used to avoid the introduction of cold or hot air in the ambient by delaying (for a set time) the fan start. To disable the function, set the time = 0.

“Disposal” The “Disposal” function is useful both for the hot and the cold channel and it helps to take off the energy stored in the fan coil radiator by delaying the fan turning off.To disable the function, set the time = 0.


Electrical CoilElectrical Coil function can be enabled in the configuration tool as “emergency”.The output provides an open collector signal (OC2) (with re-ference to signal pin 30, +12 v) to control an external auxiliary relay.The output is activated when the room temperature is lower than:

“hot” operation set - Proportional Band - 1°C

And it goes off when the room temperature is higher than:

“hot” operation set - proportional band

Auxiliry regulation ON/OFF (P action)This function can be automatically enable when the sensor in position S3 is connected. If the remote set in S4 is connected, it is possible to have a set in the range 10-30°C, otherwise it can be set through the supervisory system together with the dead zone.If the supervisory system is not present , this function will be carried on at fixed point 20°C with dead zone = 1K. The output will be available in OC2 and it will exclude the management of the electrical coil.

Air recirculation functionThis function manages the minimum fan speed. It is enabled setting a “period” and a “minimum speed” different from zero. When the “period” will be passed, the fan will be enabled at the minimum speed for the time (minutes) set.

Minimum speed activationThis function is used to prevent air stratification, especially when using the Return Sensor, as it could be very low sensitive to temperature variation that occurs at man’s height. A conti-nuous air movement helps to avoid /reduce air stratification and to optimize the regulation.A system configuration with Proportional Fan requires setting the minimum speed in % of the control value (0 - 10V). To disable this function, set 0 as minimum speed.

ISO 9001

Control modesNR9000 works with 7 different control modes selectable via dip switch or by supervisory system:

1. ON/OFF Valves and 3-speed fan (“FAST” operation mode - Operation Diagram 1).

2. ON/OFF Valves and 3-speed fan (Operation Diagram 2).3. 3-point Valves and 3-speed fan (Operation Diagram 3).4. ON/OFF Valves and 1-speed fan (Operation Diagram 4).5. 3-point Valves and 1-speed fan (Operation Diagram 5).6. ON/OFF Valves and Modulating FAN (0 – 10 V) (Operation

Diagram 6).7. 0-5/6-10 Sequence Valves and Modulating FAN (0 – 10 V).

(Operation Diagram 7).

Control modes diagrams

The 0-10V proportional outputs are always presents and they follow the ON-OFF (or 3-point) valves characteristics.

The diagrams of the valves and fans share the Set point.To make the interaction of the two devices as flexible as pos-sible the different proportional bands / Hysteresis have been thought as independent in order to define a variety of programs adaptable to different environmental situations.It is possible to enable the following function with a priority over normal operation defined by the diagrams:

• HOT/COLD LAUNCH• “DISPOSAL” FUNCTION• MINIMUM SPEED ACTIVATION

The valves are activated in ON-OFF mode with a hysteresis.Speed 1 is ON when the error (E) is greater than 10%.

2. ON/OFF Valves and 3 Speed FANThe valves are activated in ON-OFF mode with a hysteresis.Speed 1, 2 and 3 follow to the Proportional Band as shown in the following diagram.


ISO 9001

3. 3 point valves and 3 Speed FANThe valves are activated in Pro-portional mode (0-100%) using the set proportional band.Speed 1, 2 and 3 follow to the Proportional Band as shown in the following diagram.

4. ON/OFF valves and 1 Speed FAN

The valves are activated in ON-OFF mode with hysteresis.Speed 1 follows to the Propor-tional Band as shown in the fol-lowing diagram.

5. 3 point valves and 1 Speed FANThe valves are activated in Pro-portional mode (0-100%) using a proportional band.Speed 1 follows to the Propor-tional Band as shown in the fol-lowing diagram.

7. 0-5/6-10 V Sequence Valves and Proportional Speed Fan (0-10V)The valves are activated in se-quence mode (0-5/6-10) with hysteresis. If the set is satisfied the ouput is 5,5V.Fan speeds follow the Propor-tional Band as shown in the following diagram generating a 0-10V output control signal.


ISO 9001

DIP SWITCHES AND LEDsThe controller has 8 dip switches accessible by removing the top cover and two leds to check operation anomalies.

Dip switches from 1 to 4 can be used to set MODBUS devices address (up to 14) without the use of the configuration tool and to set the controller in expansion mode duplicating the outputs.If DIP 1-4 are all ON the controller is configured as expansion, duplicating the master controller outputs connected to the re-mote sensor (NR900-RT) and/or to the supervisory system.If dip switches 1 to 4 are all OFF the default ModBus address is 1 (factory eeprom setting). In case of more than 14 devices, configuration can be carri-ed out via supervisory system or using a configuration tool via Modbus protocol.Dip from 5 to 7 are used to select the operation diagram. If dip 5 to 7 are OFF the default operation diagram is nr. 2 - ON/OFF Valves and 3 Speed FAN (factory eeprom setting).Dip 8 is used to select 2/4 pipe system. If dip 8 is OFF the system is 2 pipe (factory eeprom setting).Parameters set by dip have the priority over the supervisory sy-stem. It is possible to disable the dip switch setting by ModBus.It is necessary to power down and power up the controller in case of any change in dip switches configuration. Dip Switches 1-4 settings

NR9000-RT REMOTE SENSOR

The remote sensor has 4 buttons and a 3 digit display.The functions of the sensor are:

• Room Temperature Monitoring (T AMB).• Temperature Set (button 2 & 3).• Fan Speed Set (Auto, OFF, V1, V2, V3) (button 1).• Operation Mode Set (Button 4).

The sensor has several configurations (enabled/disabled fun-ctions) that can be defined by the controller:

• Set Point DisabledIn this case the controller does not allow the user to change the set point from the Remote Terminal.

• Fan Speed Disabled

In this case the controller does not allow the user to change the fan speed from the Remote Terminal.

• Operating Mode DisabledIn this case the controller does not allow the user to change the operation modes from the Remote Terminal.

• Remote Sensor DisabledIn this case the controller does not allow the user to change all the function listed above and the remote terminal can show and send to controller only the room temperature.

It is possible to calibrate the room temperature displayed on the remote sensor of ± 3°C (label tAr) and to read and set the MODBUS address (label Add) of the controller connected to the sensor following these instructions:• press button 4 and reach the off status• press for more than 10s the button 1 (FAN)

All functionalities are enabled by default.The remote sensor has a two-coloured led to identify the opera-tion mode as shown in the following tables:
