f
Fully open thermostatic or zone valves in a lead room (e.g.
living room or bathroom).
We do not recommend installing thermostatic or zone valves
in the lead room. Control the temperature for these rooms
via a remote control.
f At different outside temperatures (e.g. -10 °C and +10 °C),
adjust the heating curve so that the required temperature is
set in the lead room.
Standard values to begin with:
Parameter Underfloor heating Radiator heat ing
system
Heating curve 0.4 0.8
Control dynamic 100 100
Comfort temperature 20 °C 20 °C
f
If the room temperature in spring and autumn is too low
(approx. 10 °C outside temperature), raise the comfort tem-
perature.
Parameter
COMFORT TEMPERATURE (SETTINGS / HEATING / HEATING CIRCUIT)
Note
If no remote control is installed, raising the comfort tem-
perature leads to a parallel offset of the heating curve.
f If the room temperature is not high enough at low outside
temperatures, increase the heating curve.
Parameter
HEATING CURVE RISE (SETTINGS / HEATING / HEATING CIRCUIT)
f
If the heating curve has been raised and no remote control
has been installed in the lead room, adjust the zone valve or
thermostatic valve in the lead room to the required tempera-
ture when outside temperatures are high.
Note
f Never reduce the temperature in the entire building
by closing all zone or thermostatic valves; instead
use the setback programs.
f Once everything has been implemented correctly, the system
can be heated to its maximum operating temperature and
vented once again.

f For underfloor heating systems, observe the max-
imum permissible temperature for that particular
underfloor heating.

12. Appliance handover
Explain the appliance function to users and familiarise them with
how it works.
Note
f Hand over these operating and installation instruc-
tions to the user for safe-keeping. All information in
these instructions must be closely observed. The in-
structions provide information on safety, operation,
installation and maintenance of the appliance.
13. Appliance shutdown
Material losses
Never interrupt the heat pump power supply, even out-
side of the heating season. Otherwise, system frost pro-
tection is not guaranteed.
The heat pump manager automatically switches the heat
pump to summer or winter mode.

f
Observe the temperature application limits and the
minimum circulation volume on the heat consumer
side (see chapter "Specification / Data table").
13.1 Standby mode
To shut the system down, simply set the heat pump manager to
"Standby mode". This way, the safety functions that protect the
system remain enabled, e.g. frost protection.
13.2 Power interruption
If the system is to be isolated from the power supply permanently,
please observe the following:
Material losses
f
If the heat pump is completely switched OFF and
there is a risk of frost, drain the system on the water
side.
14. Troubleshooting
WARNING Electrocution
f Before working on the appliance, isolate it from the
power supply at the terminal area.
Following disconnection from the power supply, parts of
the appliance may remain energised for 5 minutes until
the inverter capacitors have discharged.
Note
f
Please observe the instructions for the heat pump
manager.
Note
The following inspection instructions may only be carried
out by a qualified contractor.
