Thermia styr

Heatpumps older than 2008-03-01 with the older, “greenish” display are compatible if you can execute the following in the menu:

  1. Push and hold left and right arrow simulataneously for at least 5 sec until the display shows “Service” on top.
  2. Push “Down arrow” untill you reach item “Installation” then push “Right arrow”.
  3. Push “Down arrow” until you reach item “Node” and change the value to 2 or higher. If it’s already higher then keep the current value.

 

If you don’t have this menu and your pump is older than 2008-03-01 pump then it’s not compatible with ThermIQ.

 

The ThermIQ-MQTT interface must be connected as the first interface to the expansion port (EXT-port) of the heatpump, any other expansion board must be connected via the ThermIQ-MQTT interface.

  • ThermIQ-MQTT does not work with Thermia Atlas, Thermia Diplomat Inverter
