Activating and setting photovoltaic mode

Condition: Existing photovoltaic installation
▶
If the control for the photovoltaic installation is connected
to plug no. 1 and no. 2 on the product's PCB, you must
activate PV MODE.
◁
The electrical energy generated is stored in the form
of domestic hot water. You can set two efficiency
levels for the photovoltaic installation.
◁
PV ECO = Low level of photovoltaic power gener-
ation. The heat pump generates an increased do-
mestic hot water temperature. The increased do-
mestic hot water temperature must be between the
normal domestic hot water temperature and 60 °C.
– Factory setting: 60 ℃
◁
PV MAX = High level of photovoltaic power genera-
tion. The heat pump and the immersion heater gen-
erate an increased domestic hot water temperature.
The increased domestic hot water temperature must
be between the domestic hot water temperature of
the PV ECO mode and 65 °C.
– Factory setting: 65 ℃
▶
Turn the rotary knob to set the mode. INST.MENU PV

mode.
◁
no : Frost protection and eco mode have priority over
the signals from connection plugs no. 1 and no. 2.
Note
When photovoltaic mode has the higher prior-
ity, domestic hot water is also heated during
periods that have not been set (e.g. holiday
mode and outside of programmed time peri-
ods).
If you only want to heat the domestic hot water
during the permitted time period, set the prior-
ity to no.
▶
Press the rotary knob to confirm the selection.

Reading the input data

1. If you want to read the product's input data, you must
select this menu. DI SPLAY → INST.MENU.
2. Press the rotary knob in the DI SPLAY menu.
◁
WATE R = Domestic hot water temperature in the
central section of the domestic hot water cylinder
◁
AIR INLET = Air temperature at the air intake
◁
T_EV APOR = Temperature of the evaporator
◁
If PV MODE is deactivated:
–
SHED DING : Connection contact no. 1/low-tar-
iff contact input (0: Contact opened; 1: Contact
closed)
–
FAN CONTR. : Connection contact no.
2/hygrostat input (0: Contact opened; 1: Contact
closed)
◁
If PV MODE is activated:
–
