integration
Press the OK button. Turn the knob and select:
- Not active
- Active (by applying a 230 VAC signal to the PV input, the system fa-
vours the use of the heat pump during a heating or DHW request, to
exploit the energy produced by the photovoltaic system. If there are
no requests, it heats the DHW storage tank by increasing the set-point
by the delta set in parameter 12.0.8). Press the OK button.
Press the OK button. Turn the knob and select:

Press the OK button. Turn the knob and select:
- Not defi ned:
no function associated to the input. Fault 941 is displayed.
- Absent:
Input not enabled.
- EDF (night tariff )
: Input not active (0V).
When a 230 VAC signal is applied to the input, the system applies the
reduced electricity rate defi ned by parameter 12.9.5.
- SG Ready 1:
input signal nr 1 for the SG Ready standard
- External Switch OFF signal:
input signal to set the the machine OFF.
Every heat request, cooling request and DHW service is stopped and
antifreeze protection logics are active.

HV IN 3 (input confi gurable to 230 V)
Select the operating mode through parameter 12.1.2. Photovoltaic inte-
gration: the contacts must be connected to the relevant outlet of the
electrical power meter of the photovoltaic system.
Closing the contact produces the following eff ects:
-
Not active:
no function associated with the input.
-
PV Integration Active:
the heat pump will always be regarded as the
preferential generator for the heating function.
The boiler will only activate if the power of the heat pump becomes
insuffi cient.
(only for systems with cylinder for the production of domestic hot water
the cylinder temperature setting is raised by the value defi ned in pa-
rameter 12.0.8, so that the DHW cylinder can be used as a thermal stor-
age tank for the excess energy produced by the photovoltaic system).
