ECLYPSE Connected Terminal Unit Controller - ECY-PTU/TU Series

Key Features

The Connected Terminal Unit Controller comes with an embedded web server that enables web-based application configuration and an HTML5 visualization interface. It also features embedded scheduling, alarming, and logging. Control logic and graphic user interface can be customized as required for the application

Moreover, as part of the Smart Room Control solution, these controllers can control lighting fixtures (DALI, ON/OFF, dimming) and shades/ sunblind motors (24 VDC or 100-240 VAC, up/ down and angle rotation) through additional expansion modules.


  • Fan coil units
  • Chilled beams
  • Reversible ceilings with 6-way valves
  • Heat pumps
  • Smart Room Control solution
  • IP Communication

    • Increased speed and improved handling of numerous trend logs that enable applications such as advanced analytics that require a large amount of data.
    • Experience faster response and save time when programming, configuring, creating and viewing graphics, and upgrading your system.
    • Control technicians can connect the ECLYPSE Wi-Fi Adapter to the ECLYPSE Connected Terminal Unit Controller thereby creating a Wi-Fi Hotspot network. The control technician can then connect wirelessly to the system using a mobile device or laptop, for faster, easier system configuration, programming, commissioning and servicing.
    • Hostname management allows the controller to be addressed by a nickname to facilitate network management.
  • IP wired connection

    IP wired connection Internal switch with two Ethernet ports allows the controllers to be wired in a star or daisychain topology. With a daisy-chain topology:

    • Fewer wire runs to a centralized switch are required, thereby achieving installation and cost reduction.
    • A laptop can be connected to the second Ethernet port for direct programming, configuration, and commissioning using ECgfxProgram or ENVYSION.
  • IP wireless (Wi-Fi) connection

    The following types of Wi-Fi connections are possible when using the ECLYPSE Wi-Fi Adapter:

    • Wi-Fi Client – Connection to the building’s existing Wi-Fi network or to another controller’s Wi-Fi Hotspot or Access Point.
    • Wi-Fi Access Point – extending the building’s wired IP network to your Wi-Fi Client devices.
    • Wi-Fi Hotspot – your own wireless area network, for wireless communication between the controllers, or with a mobile device or laptop for configuration, commissioning and servicing

The ECLYPSE Connected Terminal Unit Controller is a plug and play device that saves time and money since no programming or graphic design is needed as it comes with ENVYSION™ Viewer and the associated preloaded applications and graphics are preinstalled. All standard terminal applications, such as fan coil units, chilled beams and ceilings, are included.

Also, no additional tools are required; only a web-browser is needed when you are using the pre-loaded application through ENVYSION. An Allure™ EC-Smart-Vue sensor can also be used. However, if the pre-loaded application does not meet the application requirements, it is possible to use EC-gfxProgram to program it.

  • The embedded ENVYSION viewer provides fast loading of visual applications through native web pages with absolutely no browser plug-ins. Host and view preloaded graphics, and access schedules, alarms, and trend logs directly from your ECLYPSE Connected Terminal Unit Controller.
  • xpressENVYSION offers a simplified and streamlined experience in a workflow oriented, drag & drop GUI environment while ENVYSION still offers the full customization features and editing environment.
  • Integrated Fail-Safe for Daisy-Chaining

    Controllers feature an integrated fail-safe: in case of power failure to one of the daisychained controllers, communication data is still relayed to the following controller on the daisychain. This reduces the possibility that a single point of failure will knock-out follow-on controllers, and minimizes disruption when power is cut to a controller for maintenance operations.

  • Both IP wired and wireless (Wi-Fi) connection

    The availability of both Ethernet ports and USB ports for the Wi-Fi Adapter, allows for simultaneous wired IP and Wi-Fi communication on the same controller, allowing you to choose and combine these connection methods. For example, Wi-Fi can be used between two controllers to jump a large atrium

  • Connect from anywhere

    Control technicians, facility managers, occupants, and others can easily connect to the system, on-site or off-site, using the different available tools:

    • ENVYSION to create and view the graphical interface
    • EC-gfxProgram to create custom control sequences
    • myDC Control to view, edit, and configure system operating parameters

Dedicated Inputs & Outputs

  • Universal inputs for using your preferred or engineer-specified sensors.

  • Sensor inputs to ensure optimal temperature measurement processing.

  • Digital inputs to accelerate the integration of binary inputs such as window contacts.

  • Powered Triac outputs for direct connection of valves and actuators.

  • Powered relay outputs for direct connection of ventilator fans.

  • Relay contact outputs for controlling externally powered devices such as electric heater, fans

  • Analog outputs to provide control signals for external peripherals.

  • Digital / Analog outputs for enhanced flexibility


Distech Controls’ 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.

EC-gfxProgram projects can be downloaded in batch to multiple controllers, for greater time savings. Batch firmware update can also be performed on multiple controllers

  • No External Transformer

    Some models feature a 100-240 VAC universal power supply input that allows for direct connection to the mains and do not require external transformers, for improved reliability and reduced installation costs. Some models have a 24 VAC power supply output that can be used to power analog dampers and valve actuators thereby eliminating the need for a transformer.

  • Simplified Network Commissioning

    The XpressNetwork Utility saves you time and expense by giving you increased control over multiple ECLYPSE controllers through device discovery and batch operations such as configuring and updating multiple ECLYPSE controllers on the network. In addition, with the embedded step by step Commissioning Wizard, all configuration operations can be setup and applied in one go. Increase productivity using the xpressNetwork Companion mobile app, making it easier to identify and locate a controller on the network. Use the QR Code marked on ECLYPSE controllers to easily collect key controller data and to facilitate its network integration with xpressNetwork Utility.

Supports Smart Room Control Solution

The Smart Room Control solution is an end-toend system for the control of HVAC equipment, lighting, and shades/sunblinds, achieving the highest levels of comfort for occupants while cutting costs from installation time and wiring/ material requirements to energy consumption. This solution combines:

  • Lighting and shade/sunblind expansion modules to control lights (DALI, on/off or dimming) and shades/sunblinds (24 VDC or 100-240 VAC, up/down and angle rotation).
  • Multi-sensor combining motion and luminosity (Lux) sensors and equipped with an Infrared receiver that works with a convenient remote control.
  • Wireless (infrared) personal remote control for increased occupant comfort.
