Menu 9.3.11 [S] Supply pump exer.
Pump operation can be deactivated here. Pump is in oper-
ation for 2 minutes, 12 hours after last operation.
Setting range: Off, On
Default value: On
Menu 9.3.12 [S] Supply diff HP
When the current flow temperature deviates from the set
value compared to that calculated, the heat pump is forced
to stop/start irrespective of the degree-minute figure.
Heating mode:
If the current supply temperature exceeds
the calculated supply line by a set value, the degree minute
number is set to 1. The compressor stops when there is
only a heating requirement.
If the calculated supply temperature drops below the cal-
culated flow with set value, the degree minute number is
set to the value in menu 9.1.1 minus 1. This means that
the compressor will start.
Cooling mode:
If the current supply temperature drops
below the calculated supply line with set value, the degree
minute number is set to -1. The compressor stops when
there is only a cooling requirement.
Setting range: 3 – 25 °C
Factory setting: 10 °C
Menu 9.3.13 [S] Diff HP add. heat
If additional heat is permitted (menu 8.2.1) and the current
supply line temperature falls below the calculated set value
plus the value from menu 9.3.12, the degree minute value
is set to the set value in menu 9.2.1 plus 1, until the com-
pressor has reached full speed. When the compressor has
reached full speed, the degree minute value is set to the
set value in menu 9.2.1 and additional heat is permitted.
This means that the additional heat can cut in immediately.
Setting range: 1 – 8 °C
Factory setting: 3 °C
Menu 9.3.14 [S] Block HW/Heating
If heating or hot water are not required, they can be
deselected here.

Here you select whether heat production is to be reduced
in the event of an alarm.
Setting range: Yes, No
Default value: Yes

Here you can select whether to use hot water sensors that
manage higher temperatures (above90 °C) or not.
Standard:
Standard setting
High temp:
The calculation for the HW jacket sensor (BT6),
Additional heat sensor (BT19) as well as supply temperat-
ure sensor (BT2) is replaced to suit a sensor that manages
higher temperatures (up to 110 °C). Used if new sensor is
installed in connection with installation of solar heating.
Setting range: Standard, High temp
Default value: Standard
Menu 9.3.17 [S] Freeze protection HX
Select here whether heat exchanger anti freeze is to be
active or not.
Setting range: On, Off
Default value: On
Menu 9.3.18 [S] Return
Return to menu 9.3.0.
Menu 9.4 [S] Quick start
If ”Yes” is selected, the compressor starts in the heat pump
within 4 minutes if there is a demand. However, there is
always a 30 minute compressor start delay if the current
has been switched off.
Setting range: No, Yes
Default value: No
