6.3 - PHOTOVOLTAIC SYSTEM

The internal unit UI is equipped with two inputs for connection to a photovoltaic system.
Parameter "ADDR341"
0 = disabled
1 = enabled
When one or both of the FTV inputs are closed, it is possible to automatically force the accumulation of
energy by requesting the internal unit to heat more (if in heating mode or in domestic water production) or
to cool more (if in cooling mode)
Parameter "ADDR347" cooling water delta
Parameter "ADDR348" heating water delta
Parameter "ADDR349" domestic water delta

6.4 - SOLAR THERMAL SYSTEM

The internal unit (UI) can optimise its operation to better exploit a possible solar thermal system connected
to the domestic water accumulation. It is necessary to have the connection of probe T8.
The solar thermal system shall be equipped with its own circulation pump and with the corresponding control
system.
Parameter "ADDR366"
0 = disabled
In case of management with limit temperature, when temperature T8 is higher than parameter "ADDR367",
the production of domestic hot water with heat pump is inhibited in order to exploit the energy coming from
the solar thermal system.
In case of management with temperature delta, when the difference between temperature T8 and the domestic
hot water set point is higher than the parameter "ADDR368", the production of domestic hot water with heat
pump is inhibited in order to exploit the energy coming from the solar thermal system.
For both options, if the heat pump started the domestic hot water cycle, the system always completes the
cycle with heat pump first, even if the solar thermal condition has been met.
Instead, if it started the domestic hot water cycle with the solar thermal system, when the solar condition is
not met anymore, the system switches to heat pump.
