Modbus TCP/IP - Ecriture variable INT f(liste de choix dans HA) vers un équipements

I have installed ATW-MBS-02 on my yutaki heat pump and using the following HA configuration

modbus:
  - name: hitachi
    type: tcp
    host: 192.168.12.33
    port: 502
    retry_on_empty: true
    delay: 3

and trying to shutdown it from home assistant dev tools → services

Even though it can read registers, it just cannot write to them. I have checked with an external modbus client (QModMaster), that even though the value is set for some time, it then gets reset to the previous value. Does anyone have any idea of what is happening? Should I disable something in order for it to work? Can ATW-MBS-02 work together with an PC-ARFHE controller?

Ahh just found it. I had to enable installer mode in the controller, go to « system configuration », general options, then central operation and set mode to full. Working like a charm now. Sorry for the english. Leaving the comment for future reference.
