13.2 Connection with quick-fit adaptor ZSA315
Note
If air hoses and wall outlets AWG315 are available, the
quick-fit adaptors ZSA315 can be used to connect the air
hoses to the appliance.
Observe the quick-fit adaptor installation instructions.
If the air hose is too long for the installation situation, you
may need to trim it. Cut to size using a sharp knife. The wire
spirals can be cut using wire cutters.
14. Commissioning
The commissioning of the appliance, all settings at the commis-
sioning level of the heat pump manager and instruction of the user
must be performed by a qualified contractor.
Carry out commissioning in accordance with these installation in-
structions and the heat pump manager instructions. Our customer
support can assist with commissioning, which is a chargeable
service.
Where this appliance is intended for commercial use, the regula-
tions of the Operational Safety Ordinance may apply during com-
missioning. For further details, check with your local authorising
body; in Germany for example, this is theTÜV.
14.1 Checks to be carried out before commissioning
the heat pump manager
!
Material losses
Observe the maximum system temperature for underfloor
heating systems.
Check that the heating system is filled to the correct pressure
and the air vent valve has been closed.
Check whether the outside temperature sensor and the re-
turn sensor are correctly placed and connected.
Check whether additional sensors are correctly positioned
and connected.
Check whether the power supply is connected correctly.
14.1.1 High limit safety cut-out
At ambient temperatures below -15°C it is possible that the tem-
perature controller of the electric emergency/booster heater may
trip.
Check whether the temperature controller has tripped.
Remove the cause of the fault if necessary.
Remove the side panel (see chapter “Fitting the appliance
casing”).
D0000071617
Reset the temperature controller by pressing the reset
button.
14.2 Commissioning the heat pump manager
Commission the heat pump manager and make all settings in ac-
cordance with the heat pump manager operating and installation
instructions.
14.3 Initial start-up
14.3.1 Heating curve adjustment
The efficiency of a heat pump decreases as the flow temperature
rises. Adjust the heating curve carefully. Heating curves that are
set too high result in the zone or thermostatic valves closing, which
may result in the minimum required flow rate in the heating circuit
being undershot.
Observe the WPM operating and installation instructions.
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 and bathroom).
We do not recommend installing thermostatic or zone valves
in the lead room. Control the temperature for these rooms
via a remote control.
- At different outside temperatures (e.g. -10°C and +10°C),
adjust the heating curve so that the required temperature is
achieved in the lead room.
Standard values to begin with:
Parameters Underfloor heating
system
Radiator heating
system
Heating curve 0.4 0.8
Control response time 10 10
Comfort temperature 20°C 20°C
If the room temperature is too low in spring and autumn (approx.
10°C outside temperature), open the heat pump manager menu,
select "SETTINGS / HEATING / HEATING CIRCUIT" and raise the
"COMFORT TEMPERATURE" parameter.
Note
If no remote control is installed, raising the "COMFORT
TEMPERATURE" parameter will lead to a parallel offset
of the heating curve.
If the room temperature is too low when outside temperatures are
also low, increase the "HEATING CURVE" parameter.
