ECx-Light Series

Distech Controls

The ECx-Light Series Expansion Modules are microprocessor-based interfaces that extend the number of inputs and outputs provided by the ECLYPSE™ Connected System Controllers, ECLYPSE Connected VAV Controllers, ECL/ECB-PTU Series controllers, and ECL/ECB-VAV controllers.


When connected to one of these HVAC programmable controllers, each ECx-Light-4 expansion module can control 4 On/Off lighting load and each ECx-Light-4D expansion module can control 4 On/ Off or 1-10 V dimming lighting loads.

As part of the Smart Room Control solution, the ECx-Light-4/4D expansion modules can be freely combined with ECx-Light-4DALI lighting modules and ECx-Blind-4/4LV sunblind modules to control up to 8 light groups or DALI buses, and 8 shade / sunblind motors.

  • The ECx-Light Expansion Modules operate off of a separate sub-network bus (governed by the main HVAC controller). This optimizes the control possibilities while allowing such a modular solution (HVAC controller + expansion modules) to be interpreted as a single device by the network, thereby avoiding unnecessary system overloading.

  • In addition, by positioning the expansion modules directly in ceilings, close to the lights, the installation effort is reduced. As well, connecting the module to the main HVAC controller through a single RJ-45 cable reduces wiring costs and minimizes the risk of errors.

  • Custom program the ECx-Light expansion modules directly when configuring the main HVAC controller using EC-gfxProgram. This allows you to quickly and easily create your own control sequences capable of meeting the most demanding requirements of any engineering specification.

  • Moreover, the internal electronics being powered by the host controller, the lighting load consumption can easily be monitored, allowing for energy counting, and allowing the supervisor to instantly detect abnormal power usage and anticipate bulb maintenance as part of a proactive preventive maintenance program.

Feauture and benefits

  • Part of an extensive range of lighting and shade / sunblind expansion modules that enables smart cross-management of HVAC, lighting, and shades / sunblinds as a whole, creating a unique Smart Room Control solution.
  • The main HVAC controller and its associated expansion modules form a single device on the network that reduces network traffic and facilitates BMS integration.
  • Seen as an extension of the main HVAC controller when configuring, allowing you to save engineering time.
  • Quick-link connectors for direct installation into the ceilings, or traditional detachable connectors for use with optional strain reliefs and terminal block covers. This may eliminate the need for a protective enclosure in some jurisdictions.
  • Integrated digital inputs to interface with light switches, window contacts, etc…
  • Separate power supply for loads and internal electronics allows for dedicated metering, leading to more accurate energy consumption analysis.
  • Fail-safe mode to comply with most regulation requirements

The Smart Room Control solution combines a main HVAC Controller with expansion modules dedicated to lighting and sunblind management to form a modular solution that uses a single point on the network.
