Warning: setting heating On/Off may be more complex than just setting ID_Ba_Hz_akt

[kivadiu]

I would like to report some troubles I had with switching On/Off my heating. I initially thought that setting ID_Ba_Hz_akt to Automatic or Off was enough but in fact more parameters need to be changed to have the same behaviour as doing it physically on the control panel of the heat pump.

Thanks to @Bouni and his script allowing to dump all parameters of the heatpump, I was able to see that setting On/Off my heating was changing at least 4 parameters:

Heating Mode	ID_Ba_Hz_akt	ID_Ba_Hz_MK1_akt	ID_Ba_Hz_MK2_akt	ID_Ba_Hz_MK3_akt
Automatic	Automatic	0	0	Automatic
Party	Party	2	2	Party
Off	Off	4	4	Off

For reference, my heat pump is Alpha Innotec LW 150A (type L2A).

The problem I had when I changed only ID_Ba_Hz_akt was that if I turned off the heating manually on the controller and turned later on with HA, my heated floor did not restart because the target M1 flow temperature said at 15°C. After I discovered I had to change 4 parameters, it worked well. I thought it was worth sharing.
