Commissioning the heat pump
Wait approximately 5 minutes after switching off the compressor before activating
rapid restart of the heat pump, to allow the cooling circuit time to equalise pressure.
In the menu 5.7 you set whether the heat pump, additional heat and hot water
charging should be controlled externally. When the external input on the control
unit is short circuited you can make one of the following choices:
0 : No effect (factory setting).
1 : HP, additional heat and hot water stop.
2 : HP no effect, additional heat and hot water stop.
3 : HP and hot water no effect, additional heat stops.
4 : HP and additional heat no effect, hot water stops.
Select the language that you would like for the menu texts.
The heat pump is set for continuous operation of the heat carrier pump on delivery.
In systems with a bypass, you can choose whether the heat carrier pump starts and
stops with the compressor.
Choose whether the heat transfer fl uid pump shall run continuously, for example,
when using *natural cooling. The heat transfer fl uid pump should in normal mode
always start and stop with the compressor.

* Natural cooling: In winter the heat pump takes heat from the bore hole in the rock and converts this to
heat in the house. In the summer the cold in the same bore hole is used to give pleasant air conditioning.
If any of the alternatives to the left are
selected it is not possible to utilise any
of the functions in the menu Remote
control temperature (menu 1.13). See
Extra functions in the user section.
