The ECB-103 is a microprocessor-based programmable controller designed to control terminal units such as fan coil unit, heat pump unit, unit ventilator, and chilled ceilings. This controller uses the BACnet® MS/TP LAN communication protocol and is BTL®-Listed as BACnet Application Specific Controllers (B-ASC).


BACnet B-ASC 10-Point Programmable Controllers

These controllers meet the requirements of the following applications:

  • Fan Coil Units
  • Heat Pumps
  • Unit Ventilators
  • Chilled Ceilings


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. Available with an optional Wireless Receiver that supports up to 18 wireless inputs to create wire-free installations

  • Increased Energy Efficiency

    Improves energy efficiency when combined with:

    • Motion detectors to automatically adjust a zone’s occupancy mode from standby to occupied when presence is detected
    • CO2 sensors as part of a demand-controlled ventilation strategy that adjusts the amount of fresh air intake according to the number of building occupants
    • Light switches to control both lighting and a room’s HVAC occupancy / standby mode setting



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.

  • 4 universal inputs
  • 4 digital outputs (TRIAC) that supports internal supply of 24 VAC, simplifying wiring of outputs such as floating actuators
  • 2 universal outputs
  • 15 VDC power supply to power 4-20mA transducers


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 .
