    Good day!

    I finally got around to installing the Thermiq MQTT/ROOM2 and all is working well. The only thing that’s unclear right now is if setting EVU = 1 should stop a running compressor? Or does this only block the starting of the compressor. Right now, it doesn’t seem to stop the heatpump when it’s working. Is that expected for this model? Or is there a way to ”unlock” this behavior?

    Thank you for creating this hardware, it’s going to save me a lot of headaches this winter!

    Kind regards,
    Johan

    EVU=1 stops the heatpump regardless of current mode and settings. Please check your wire connections. They are polarized and cannot be switched.
