Reset the high limit safety cut-out by pressing the reset
button.
11.1.4 Temperature sensor
- Have you correctly located and connected the outside tem-
perature sensor and the return temperature sensor (in con-
junction with a buffer cylinder)?
11.1.5 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.
11.2 Heating curve adjustment during
commissioning
The efficiency of a heat pump decreases with rising flow temper-
ature. The heating curve should therefore be adjusted with care.
Heating curves that are adjusted too high lead to the zone and
thermostatic valves closing, which may lead to the minimum flow
rate required for the heating circuit not being 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 a start:
Parameter Underfloor heating
system
Heating system with
radiators
Heating curve 0,4 0,8
Controller dynamics 5 15
Room temperature 20 °C 20 °C
If the room temperature in spring and autumn is too low (approx.
10 °C outside temperature), the parameter “Room temperature”
must be raised.
Note
If no remote control is installed, raising the parameter
“room temperature” leads to a parallel offset of the heat-
ing curve.
Increase the parameter “HEATING CURVE” if the room temperature
is not high enough when outside temperatures are low.
If the parameter “Heating curve” has been raised, adjust the zone
or thermostatic valve in the lead room to the required temperature
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.
11.3 Operation and control
!
Appliance and system damage
Never interrupt the power supply outside the heating
period. The system‘s active frost protection is not guar-
anteed if the power supply is interrupted.
The system should not be switched off in summer. The heat pump
manager has an automatic summer / winter changeover.
11.4 Taking the appliance out of use
If the appliance is to be taken out of use, set the heat pump manag-
er to standby. This retains the safety functions designed to protect
the system (e.g. frost protection).
!
Appliance and system damage
If the heat pump and frost protection are completely
switched off, drain the system on the water side.
