B Indicate the delay that is required until the
groundwater circuit circulates. The compressor
should not start before this has taken place.
>> Time for reset of access level
B Set how much time it should take for the control unit
to return automatically from installer level to
customer level.

All boards and current version are displayed, if relevant.
> Compressor working area
This defines a number of functions that make the
compressor stop temporarily or change operating mode
to avoid more serious alarms.
>> Hot gas stop function activated
B Select Yesif the stop function should be active.
The function protects the compressor when the hot
gas temperature exceeds the factory value for
maximum hot gas temperature. If the heat pump goes
into hot water mode the compressor returns to
heating mode and any electrical add heat hot water is
activated. The value for T3 is saved. The stop function
is deactivated when T3 falls 5K below the saved value.
If the hot gas temperature is too high for heating
mode the outdoor temperature T2 is saved and the
compressor stops. T2 must rise a few degrees and the
timer temporary stop must count down before
compressor may start.
>> Outdoor stop function activated
B Select Yes if the stop function should be active.
The compressor stops when the outdoor temperature
falls below the lowest permitted outdoor temperature
for the compressor (-20 °C). When the outdoor
temperature rises to a value that is higher than the
lowest permitted temperature and this continues for
30 minutes (factory value), the stop function is
deactivated and the compressor starts automatically
if there is a demand.
> Generated energy
This displays Generated energy in kWh divided into
Heating and Hot water.
> Operating times and consumptions
The total operating time for the control unit, heat pump
x and additional heat (active connection). It can also
make short term measurements for compressor and
additional heat.
> Temperatures
All connected/acknowledged sensors present values.
The set point value is also given for some. The
opportunity to correct the sensors is also given.
Open circuits/short circuits/faults in sensors are
indicated with a dash in the display and under
Temperatures. Alarms are triggered and stored in alarm
log and alarm history.
