The ECL-103 is a microprocessor-based programmable controller designed to control terminal units such as fan coil units, heat pump units, unit ventilators, and chilled ceilings. This controller uses the LonTalk® communication protocol and is LONMARK certified as an SCC Generic device, guaranteeing compatibility and interoperability with other manufacturers’ LonMark certified controllers.

These controllers meet the requirements of the following applications:

Fan Coil Units, Heat Pumps, Unit Ventilators and Chilled Ceilings


LONMARK® Certified 10-Point Programmable Controller
  • 4 universal inputs
  • 4 digital (Triac – internally or externally powered)
  • 2 universal outputs
  • Supports up to 4 Allure series communicating sensors
  • Open-to-Wireless™: support of wireless battery-less inputs
  • LONMARK® certified


Flexible Inputs and Outputs

This controller has various input types including resistance, voltage, and digital-based ones. Moreover, it provides digital, floating, pulse width modulation, and proportional control outputs for valves, heating elements, fans, and lighting applications. This controller covers all industry-standard HVAC unitary applications.

Highly Accurate Universal Inputs

Highly accurate universal inputs support thermistors and resistance temperature detectors (RTDs) that range from 0 Ohms to 350,000 Ohms, as well as support for inputs requiring 0 to 10VDC or 0 to 20mA with an external resistor. This provides the freedom of using your preferred or engineer-specified sensors, in addition to any existing ones.
  • Rugged Inputs/Outputs

    Rugged hardware inputs and outputs eliminate need for external protection components, such as diodes for 12V DC relays.

  • Open-to-Wireless

    The controllers are Open-to-Wireless™ ready, and when paired with the Wireless Receiver, work with a variety of wireless battery-less sensors and switches, to reduce the cost of installation and minimize the impact on existing partition walls. For supported frequencies in your area, refer to the Open-to-Wireless Solution Guide. Available with an optional Wireless Receiver that supports up to 18 wireless inputs to create wire-free installations.


Supports EC-gfxProgram

Supports Distech Controls’ EC-gfxProgram, which makes Building Automation System (BAS) programming effortless by allowing you to visually assemble building blocks together to create a custom control sequence for any HVAC / building automation application.

Allure™ Series

Allure™ Series Communicating Sensor Support

These controllers work with a wide range of sensors, such as the Allure Series Communicating Sensors that are designed to provide intelligent sensing and control devices for increased user experience and energy efficiency

  • Allure EC-Smart-Vue sensors feature a backlit-display and graphical menus that provide precise environmental zone control, with any combination of the following: temperature, humidity, CO2 , and motion sensor.
  • Allure EC-Smart-Comfort sensors feature colored LED indicators to provide user feedback, rotary knobs to adjust the setpoint offset and fan speed, and an occupancy override push button. This sensor can also be expanded with a combination of up to 4 addon push button modules for lighting and shade/ sunblind control.
  • Allure EC-Smart-Air sensors combine precise environmental sensing in a discreet and alluring enclosure for temperature, humidity, and CO2
