the solar panel are enabled to work (valve is open and water pump on); heating probe is defined by FS58
parameter (it is possible to set another probe, if needed).
Compressors are normally managed by heating regulation.
Solar panel in Heating (FS56=2)
If:
solar panel temperature – heating temperature > FS60 (Dt to enable solar panel in heating)
the solar panel are enabled to work; heating probe is defined by FS58 parameter (it is possible to set another
probe, if needed).
At first compressors are not used for heating.
It is possible to set a maximum time to use solar panel (FS61); when this time is elapsed and sanitary set
point is not reached, the solar panel are disabled and compressors are switched on.
In regulation, if
solar panel temperature – heating temperature < FS60
the solar panel are disabled and the heating is done by compressors.
Dt control is done only at the time of the request of heating; if Dt< FS60 the solar panel are not used and
compressors are used for heating.
