Thermostat keeps turning off no Target Temperature


i try to automate my radiator Thermostats.
But everytime I set the value it goes out of heating mode.
Then i cant set my Target temperature because the field keeps disappearing.

Thats why my scenes cant sent the value in my automation and nothing happens on trigger.

I am using “SPZB0001” from Eurotronic. I attached an image of the empty field.
Previous version of Home assistant gave me the option to set the temperature regardless.

If i request Systemmode through the cluster it switches the Thermostat to Heating and then i am able to set the target temperature.

Does anyone have an idea how i can fix keeping the target temperature to be always visible?
Or am I doing something wrong?

Thanks in advance for the help. :slight_smile:

(I am a new user, I was only able to post one image. I have 2 other images of the value being able to be set after requesting the system mode to heating.)

(Cluster: ThermostatCluster (Endpoint id: 1, Id: 0x0201, Type: in; Attribut: system_mode (id: 0x001c); request State button pressed → Target temperature can be set)

Edit: Forgot to add that i cant use the Action field on the thermostat. If i switch to heating nothing happens.
