The unit can be programmed to deliver hot water from

The PV function is not active. If this function is activat-
ed, the heat pump and the electric heater can start
only if the input voltage in GC1 (0-10V) is higher than
D20/D21 (PV min Voltage HP/EL) for longer than D22
(PV min time).

PV ECO*
The PV function allows for water heating only with the
heat pump until temperature set point defined by the
MODE of operation is reached.
PV
STORAGE *
The PV function allows for water heating to the
maximum temperature level, giving priority to the
operation of the heat pump if the BOOST or BACK UP
mode is not active. The heat pump operates alone until
the max allowed temperature for the heat pump oper-
ation D33 (T HP Max) is reached. The electric heater
operates only from D33 to the maximum allowable
temperature D9 (Water T max).
B6 Solar*
The Solar function allows the water to be heated up by
the solar collector, activating a water pump controlled
by the extra relay (GP1). The pump starts when T5 > T3
+ D24 (Solar DT min). The pump stops if the tempera-
ture in the tank goes above D23 (Solar T max) or if T5
is below T3.
OFF/ON OFF
B7 Floor*
The floor heating function activates an external circu-
lation pump. If the temperature at the bottom of the
tank T4 (T water b) is higher than the setting menu D25
(Floor T start) the floor heating function is activated.
If the extra temperature T5 (T Extra) is higher than the
floor heating temperature (B8 T floor) the circulation
pump (Extra relay GP1) stops.
