Testing the auxiliary heating power stages
25. Start the first auxiliary heating power stage by setting the value
ADD.HEAT 3 to 1.
26. Check that the auxiliary heating power stage works by leav-
ing the menu MANUAL TEST and going into the menu
INFORMATION -> TEMPERATURE -> WARMWATER and check that
the temperature rises.
27. Return to the menu MANUAL TEST and stop ADD.HEAT 3 by set-
ting the value back to 0.
28. Repeat steps 25 to 27 for ADD.HEAT 6.
Test fuse protection
29. Start the compressor by setting the value HEATPUMP to 1.
30. At the same time, start the auxiliary heating power stages avail-
able to check that the fuse protection can withstand full power
operation.
Test the outdoor unit for DHP-A
31. Start the defroster shunt by setting the value SHUNT DEFR to 1.
32. Start the fan at low speed by setting the FAN L value to 1.
33. Check that the fan runs at low speed.
34. Start the fan at high speed by setting the FAN H value to 1.
35. Check that the fan runs at high speed.
Exit test operation
34. Set the value for MANUAL TEST to 0.
Auxiliary start of circulation pumps
If any of the circulation pumps do not start, it may need to be
helped as follows:
Figure 50: Bleed screw location .
1. Open and remove the bleed screw on the front of the pump.
Normally a small amount of water comes out when it is
removed.
2. Insert a flat blade screwdriver and turn it in the direction of
rotation of the pump (clockwise).
3. Reinstall the bleed screw with its rubber seal.
Adaptation to the heating system
Adjust the heat pump settings to the applicable heating system,
for instance an underfloor heating or radiator system. The delta
temperature must be at least 8°C above the heat pump. The delta
temperature should be 3-5°C for the brine system. (The flow rate of
the circulation pumps may need to be adjusted depending on the
applicable heating system)
Noise check
During transportation and installation there is a certain risk that the
heat pump can be damaged, components may move or get bent
and this can cause noise. Because of this it is important to check
the heat pump when it has been installed and is ready to be com-
missioned to ensure that everything seems in order. The heat pump
should be run in both heating and hot water modes to ensure that
there is no abnormal noise. While doing this, check that there is no
abnormal noise in other parts of the house.
Noise is produced from the outdoor unit when the fan is in opera-
tion, check during that manual operation that there is no distur-
bance in your own home as well as to any neighbours.
Select operating mode
Set the heat pump to the desired operating mode in the menu
INFORMATION -> OPERAT. If necessary, set certain parameters in the
control computer, such as ROOM and CURVE.
9 .3 Installing the front cover
⚠
NOTE! Take care not to damage the front cover!
1. Align the upper section of the front cover with both the side
channels at the top of the unit and slide it carefully downwards
until it covers the entire front of the unit.
2. Tighten the screws.
9 .4 After start up
NOTE! Remember that it takes time for the heat pump to heat
⚠
a cold house. It is best to let the heat pump work at its own
pace and NOT raise any values in the control computer to try
to heat it up more rapidly.
