Commissioning/Ser vice
Make a check of all the functions before you commission the heat pump.
You can manually start and stop the pumps and valves from the menu-
Manual operation of all functions. For 1-phase heat pumps the compressor
may not be restarted within 10 minutes. This can cause serious damage
to the heat pump!
Set when the additional heat should be activated. On delivery the heat
pump is set to activate the additional heat when necessary. Choose
between Yes or No. If you choose No, the additional heat only engages
during alarms, extra hot water and hot water peaks.
Only for 3-phase heat pumps: The function Fast restart means you do
not have to wait for the normal restart time to start the heat pump. If there
is a need for heating or hot water the heat pump starts within 20 seconds.
The setting must be repeated each time you need to make a fast restart.
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. On delivery the
language setting is set to Svenska.
The heat pump is set for continuous operation of the heating carrier pump
on delivery. In systems with a bypass, you can choose whether the heating
carrier pump starts and stops with the compressor.
Choose whether the HTF pump shall run continuously, for example, when
using *natural cooling. The heat transfer fl uid pump should normally
always start and stop with the compressor. On delivery the heat pump is
set to start and stop with the compressor.
Select this menu to see the version number of the control unit.
Confi rm the extra sensors T3 (GT3), T4 (GT4) and T5 (GT5) that are
connected externally. On confi rmation, the control unit stores information
about the sensors to be used.
* Natural cooling: In the 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 temp (menu 1.13). See Extra
functions in the user section.
