Distech Controls ECL-103 Series 2019-04-01T10:47:33+00:00

ECL-103 Series

Distech Controls

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. These controllers meet the requirements of the following applications: Fan Coil Units, Heat Pumps, 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.

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.


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.
