[Feature Request] Allow changing the group setting for the heating mode (air/radiant/combined)

[tnolf]

I was wondering if it is possible to allow changing the group setting for heating mode in Airzone through HA?
The parameter on the group entity is called user_device_heat_stages_conf with possible value being "off", "air", "radiant" and "combined".

What this would be helping with is to automatically switch heating to radiant during the day when solar panels produce free energy and then when the sun goes down switch to air because it is more effective and takes less energy.

Thanks!
