Danfoss Ally can't change temperature and state does not change to idle

Hi there

I installed three new Danfoss Ally Thermostats. But the new thermostats do not change the State to Idle (are always on Heat) and I’m unable to adjust the temperature. I’m able to read the temperature in Home Assistant. In the Danfoss App everything. is working fine

Does anyone have an idea what I’m doing wrong? The “old” Thermostats are working properly.

Thanks in advance.
