ROOM TEMPERATURE ANTIFREEZE (ONLY WITH ZONES ACTIVE)

Protection is related to the value read by the room air temperature probe N-THC.
The involved resources are the compressor (J10) and the delivery heater (NO8)
The purpose of this function is to protect the internal ambient from excessive cold. When active, it uses the available resources as configured for
normal system heating (HP, delivery heater, alternative heat source), based on the function described below:
The Heat Pump will work based on the set antifreeze setpoint (default = 5°C); if inhibited (for the details refer to the "Replacement heater" and
"Replacement heat source" paragraphs), the other available resources will be activated.
For the default values of the various parameters, see the parameters table
