Adapting the unit to the installation
8.1
Calling up the installer level
1.
Press the menu button.
2.
Turn the rotary knob until the
INST.MENU
menu ap-
pears in the display.
3.
Hold down the clock button and the menu button for
three seconds.
◁
The first menu item of the installer level
PV MODE
is displayed.
8.2
Optimising the unit's energy consumption
The domestic hot water generation can take place using a
back-up heater via the integrated heat exchanger.

Caution.
Risk of destruction of the PCB.
If there is a voltage of 230 V at the floor-
standing boiler contact, there is a risk that the
PCB will be damaged.
▶
Measure the voltage before connecting.
▶
Remove the covering hood. (

▶
Remove the black covering hood from the PCB.
▶
Use a two-wire cable (each with a cross-section of 1.5
mm
²
to connect the potential-free contact between output
14-15 on the PCB of the thermodynamic water heater
and the back-up heater's thermostat input.
Note
The output alarm is not activated. It is conver-
ted to a control output for the floor-standing
boiler.
The end user can select either the electric
back-up heater or the floor-standing boiler
(e.g. summer or winter mode). The electric
back-up heater is selected by default.

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
℃
