The amount of modules that you need depends on the properties of your system. Consult the wiring diagrams to fully understand the requirements.

You need:

  • one free output contact on the analogue control module(s) for each zone equipped with a fan coil unit that you want to connect

  • one free output contact on the heating or cooling module(s) for each zone equipped with a thermal actuator valve that you want to connect

  • one or two free contacts to connect to the heat pump (check the requirements and wiring diagrams of your specific heat pump):

    • one to signal heating/cooling demand

    • one to signal heating/cooling selector (only needed if your heat pump is capable to provide both warm and cool water)

*For example, in a configuration with two zones for heating and cooling, you will use one heating or cooling module which has up to four HVAC contacts.

Third party requirements

Your system meets the following requirements:

  • It is a fan coil unit, that contains a water loop and a fan.

  • Your device can be controlled via:

    • one thermal actuator valve for each zone

    • one 0–10 V contact for each zone

  • It is connected to a heating and/or cooling unit for hydronic applications, such as a heat pump, boiler, etc.

Also check the specific requirements for your water source (heat pump, boiler, etc.)
