ECL-PTU SeriesLonMark® Certified Powered Terminal Unit Programmable Controllers

OverviewThe ECL-PTU Series controllers aremicroprocessor-based programmablecontrollers designed to control powered terminalunits such as powered fan coil units, heatpumps units, and chilled beams.Each controller uses the LonTalk®

communication protocol and is LONMARK certifiedas an SCC Fan Coil Controller.These controllers are optimized for ultra-lowpower consumption and can be operated asstand-alone units or as part of a networkedsystem to suit any installation requirement

ApplicationsThese controllers meet the requirements of thefollowing applications:£ Fan Coil Units£ Heat Pumps£ Chilled Beams£ Reversible Ceiling with 6-way valves£ Lighting fixtures and shade / sunblind

motors when associated to ECx-Light/BlindSeries expansion modules

Features & BenefitsPreloaded ApplicationsFactory preloaded applications allow thesecontrollers, straight out of the box, to operatestandard PTU equipment with a proven energy-efficient sequence of operation therebyeliminating the need for programming.The preloaded application can be selected usingan Allure EC-Smart-Vue sensor even before thenetwork has been installed for rapid deploymentor through the EC-Net™ solution using DistechControls’ dcgfxApplications.

2 / 16 ECL-PTU Series

ProgrammabilitySupports Distech Controls’ EC-gfxProgram,which makes Building Automation System(BAS) programming effortless, by allowing youto visually assemble building blocks to create acustom control sequence for any HVAC ,lighting, or building automation application.

Dedicated Inputs & OutputsEach controller has specific IOs to fulfill any typeof installation:£ Universal inputs for using your preferred or

engineer-specified sensors.£ Sensor inputs to ensure optimal temperature

measurement processing.£ Digital inputs to accelerate the integration of

binary inputs such as window contacts.£ Powered Triac outputs for direct connection

of valves and actuators.£ Powered relay outputs for direct connection

of ventilator fans.£ Relay contact outputs for controlling

externally powered devices such as electricheater, fans, ...

£ Analog outputs to provide control signals forexternal peripherals.

£ Digital / Analog outputs for enhancedflexibility

Depending on the installation configuration andcontrolled equipment (valves, fans…), thesuitable model will allow for simplifiedinstallation and wiring, and eliminate the needfor additional external power supply.

Increased Energy EfficiencyImproves energy efficiency when combinedwith:£ Motion detectors to automatically adjust a

zone’s occupancy mode from standby tooccupied when presence is detected

£ CO2 sensors as part of a demand-controlledventilation strategy that adjusts the amountof fresh air intake according to the numberof building occupants

£ Light switches to control both lighting and aroom’s HVAC occupancy / standby modesetting

Smart Room Control SupportThe Smart Room Control solution is an end-to-end system for the control of HVAC equipment,lighting, and shades/sunblinds, achieving thehighest levels of comfort for occupants whilecutting costs from installation time and wiring/material requirements to energy consumption.This solution combines:£ Lighting and shade/sunblind expansion

modules to control lights (DALI, on/off ordimming) and shades/sunblinds (24 VDC or100-240 VAC, up/down and angle rotation).

£ Multi-sensor combining motion andluminosity (Lux) sensors and equipped withan Infrared receiver that works with aconvenient remote control.

£ Wireless (infrared) personal remote controlfor increased occupant comfort.

£ Allure™ Series Communicating Sensors forincreased occupant comfort settings.

Open-to-Wireless™ Solution

The controllers are Open-to-Wireless™ ready,and when paired with the Wireless Receiver,work with a variety of wireless battery-lesssensors and switches, to reduce the cost ofinstallation and minimize the impact on existingpartition walls. For supported frequencies inyour area, refer to the Open-to-WirelessSolution Guide.Available with an optional Wireless Receiverthat supports up to 24 wireless inputs to createwire-free installations.

Allure™ Series Communicating Sensor SupportThese controllers work with a wide range ofsensors, such as the Allure SeriesCommunicating Sensors that are designed toprovide intelligent sensing and control devicesfor increased user experience and energyefficiency.£ Allure EC-Smart-Vue sensors feature a

backlit-display and graphical menus thatprovide precise environmental zone control,with any combination of the following:temperature, humidity, CO2, and motionsensor.

ECL-PTU Series 3 / 16

£ Allure EC-Smart-Comfort sensors featurecolored LED indicators to provide userfeedback, rotary knobs to adjust the setpointoffset and fan speed, and an occupancyoverride push button. This sensor can alsobe expanded with a combination of up to 4add-on push button modules for lighting andshade/ sunblind control.

£ Allure EC-Smart-Air sensors combineprecise environmental sensing in a discreetand alluring enclosure for temperature,humidity, and CO2.

Supported Platforms

The EC-NetAX multi-protocol integration solutionis web-enabled and powered by the NiagaraAX

Framework, establishing a fully Internet-enabled, distributed architecture for real -timeaccess, automation and control of devices. TheEC- NetAX open framework solution creates acommon development and managementenvironment for integration of LONWORKS®,BACnet ® and other protocols. Regardless ofmanufacturer and protocol, the EC-NetAX systemprovides a unified modeling of diverse systemsand data, providing one common platform fordevelopment, management and enterpriseapplications.

LONWORKS Network Services

The LNS® client-server platform allows multipleusers, running different LNS-compatibleapplications, to access a common source fordirectory, installation, management, monitoringand control services for the network systembeing managed. Distech Controls’ Lonwatcher isan example of a LNS-based networkmanagement tool that can use Plug-Ins toconfigure and monitor controllers and devices inthe control system.

No External TransformerControllers in this series feature a 100-240 VACuniversal power supply input that allows fordirect connection to the mains and do notrequire external transformers, for improvedreliability and reduced installation costs.Some models have a 24 VAC power supplyoutput that can be used to power analogdampers and valve actuators therebyeliminating the need for a transformer.The ECx-Blind-4LV models have an embeddedpower supply that can eliminate the need for anexternal power supply to power the controlleddevice.

Ultra-low Power ConsumptionCareful attention was paid to the design of thesecontrollers as well as to the selection of theircomponents for optimal energy management.This provides ultra-low energy consumptionwhile providing high-level control performance.

Reduced Installation Time & CostOptional strain relief and terminal block coversprovide enhanced electrical protection that canreduce installation costs by eliminating the needfor a protective enclosure (when allowed bylocal regulations).Moreover, powered digital outputs allow fordirect connection of controlled loads to saveinstallation time and wiring costs.

eu.bac Certified Control Efficiency(pending)The eu.bac certification schemes guaranteesthe highest level of performance of the productsand systems, as defined in the EU-Directivesand relevant EN standards. This allows buildingowners to ensure that their building keepsperforming as well, or better than when it wasfirst commissioned.
