Compressors are normally managed by domestic hot water temperature and domestic hot water set point.
if domestic hot water temperature < FS23-FS24, the valve of the solar panel is open and the water pump
is on
if domestic hot water temperature > FS23, , the valve of the solar panel is close and the water pump is off
Solar panel in heating mode (FS55=2)
If:
solar panel temperature – domestic hot water temperature > FS59 (Dt to enable solar panel in
domestic hot water)
the solar panel are enabled to work; domestic hot water probe is defined by FS57 parameter (it is possible to
set another probe, if needed).
At first compressors are not used for domestic hot water.
It is possible to set a maximum time to use solar panel (FS61); when this time is elapsed and domestic hot
water set point is not reached, the solar panel are disabled and compressors are switched on.
The domestic hot water pump runs when solar panel are enabled.
In regulation, if
solar panel temperature – domestic hot water temperature < FS59
the solar panel are disabled and the hot domestic hot water is done by compressors.
Dt control is done only at the time of the request of domestic hot water; at this moment, if Dt< FS59 the solar
panel are not used and compressors are used for heating.
39.2 SOLAR PANEL IN HEATING MODE
Solar panel in integration mode (FS56=1)
If:
solar panel temperature – heating temperature > FS60 (Dt to enable solar panel in heating)
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 domestic hot
water 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.
40. UNIT WITH HYBRID EXCHANGERS (AIR / WATER UNIT)
The parameter CF75=1 enables this function.
This unit manages two exchangers by relay:
- Hybrid exchanger 1
- Hybrid exchanger 2
