ECL-300 Series

ECL-300 Series

The ECL-300 Series controllers are microprocessor-based programmable controllers designed to control equipment such as air handling units, chillers, boilers, pumps, and cooling towers.

ECL-300 Series

LONMARK® Certified 18-Point Programmable Controllers

The ECL-300 can also be used for lighting control and power measurement applications. This controller uses the LonTalk® communication protocol and is LONMARK certified as a Static Programmable Device, guaranteeing compatibility and interoperability with other manufacturers’ LONMARK certified controllers.

These controllers meet the requirements of the following applications:

  • Air Handling Units
  • Chillers
  • Boilers
  • Cooling Towers
  • Heat-Exchangers
  • Pumps
  • Lighting Control

Universal Inputs and Outputs

This controller has various software configurable universal inputs and software configurable universal outputs, and covers all medium to large-size industry-standard HVAC applications.

Rugged Inputs/Outputs

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



Supports EC-gfx Program

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.

  • 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 28 wireless inputs to create wire-free installations.

  • 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 a pulse count. 0-20mA inputs and outputs have a jumper that eliminates the need for external resistors. This provides the freedom of using your preferred or engineer-specified sensors, in addition to any existing ones. The first four universal inputs support fast pulse count reading up to 50 Hz for gas, water, and electric meters and are compatible with an SO rated (optically-isolated) output.


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 add-on 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 .


Operator Interface

ECL-350 Model

The ECL-350 model has a full-color backlit display and a jog dial for turn and select navigation to access a wide range of internal controller functions:

  • View and override values. The status is color coded to show if the value is overridden.
  • Visually tune PID loops with system response graphing.
  • View active alarm list
  • View and modify schedules and calendars through a graphic interface. Also create or delete schedule events, special events, and calendar entries.
  • Create a list of favorites to provide quick access to commonly-used values.
  • Multi-User access management.
  • Multilingual interface: English, French, German, etc
