13.1.5 Power supply
- Have you correctly connected the power supply?
- The compressor turns in the right direction if, when volt-
age is applied to the heat pump power supply (mains), no
fault message appears in the display. If the fault message
NO OUTPUT appears, reverse the rotational direction of the
compressor.
13.2 Heating curve adjustment during
commissioning
The efficiency of a heat pump decreases as the flow temperature
rises. Therefore adjust the heating curve with care. A heating
curve that is set too high leads to the zone and thermostatic valves
closing and the minimum flow rate required for the heating circuit
may not be achieved.
The following steps will help you to adjust the heating curve cor-
rectly:
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 remote control.
At different outside temperatures (e.g. -10 °C and + 10 °C),
adjust the heating curve so the required temperature is set in
the lead room.
Standard values for the start:
Parameter Underfloor heating
system
Radiator heating
system
Heating curve 0.4 0.8
Control dynamic 10 10
Comfort temperature 20°C 20°C
If the room temperature in spring and autumn is too low (approx.
10 °C outside temperature), the COMFORT TEMPERATURE param-
eter must be raised.
Note
If no remote control is installed, raising the COMFORT
TEMPERATURE parameter leads to a parallel offset of the
heating curve.
If the room temperature is not high enough at low outside tem-
peratures, increase the HEATING CURVE parameter.
If the parameter HEATING CURVE has been raised, adjust the zone
valve or thermostatic valve in the lead room to the required tem-
perature at high outside temperatures.
Note
Never reduce the temperature in the entire building by
closing all zone or thermostatic valves, but by using the
setback programs.
