ECL-203 Series

Distech Controls

The ECL-203 Series controllers are microprocessor-based programmable controllers designed to control terminal units such as rooftop units, fan coil units, unit ventilators, heat pump units, air handling units, and chilled ceilings.

GET A QUOTE

The ECL-203 Series controllers use 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: Rooftop Units, Fan Coil Units, Chilled Ceilings, Heat Pumps, Unit Ventilators and Small Air Handling Units

LONMARK® Certified 14-Point Programmable Controllers

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.

Overview

  • Custom programming of applications
  • 6 universal inputs
  • 5 digital (Triac) outputs
  • 3 universal outputs
  • Scheduler objects with 7 weekday templates and 4 holiday templates per scheduler
  • Some models available with environmental protection
  • ECL-253 includes live graphics color display (integrated LCD operator interface)
  • Supports up to 4 Allure series communicating sensors
  • Open-to-Wireless™ Solution: support of wireless battery-less inputs
  • LonMark® certified
  • LonMark® certified controllers designed to meet oil and gas industry standards

Rugged Inputs/Outputs

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

Environmental Protection

The ECL-203 model with Environmental Protection has a conformal coating applied to its circuit board for an extra degree of protection for use in humid regions and it is ideal for enclosed roof-top unit applications.

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 24 wireless inputs to create wire-free installations.
