Without external sensor
If there is no external sensor installed, only for calculating
the convenience between generators, the electronics takes
the value of the virtual outdoor temperature = 0°C as the
reference.
The user can decide whether to force the convenience of the
Heat Pump by suitably setting the value of PAR 42.
Activation of the convenient generator
The convenient generator (boiler or Heat Pump) is activated
and switched off on the basis of the comparison between the
set delivery temperature and the temperature measured by
the system delivery sensor (SMI).
NOTE
If the Heat Pump is unable to satisfy the system's heat
requirements, after the stand-by time settable through Par 43
(default = 3 min – Range = 1–60 min), the boiler activates to
integrate the power required.
NOTE
The symbol "+" appearing on the board's display symbolises
the activation of the Heat Pump.
+ On = Heat Pump on
+ Off = Heat Pump off
POSSIBLE BOILER FAULTS
In the event of any boiler faults, the boiler will remain off
and the Heat Pump and the system delivery pump (PMI) will
activate.
Domestic hot water will NOT be produced.
