Miscellaneous
Control
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 flow temperature exceeds
the calculated flow with set value, the degree minute
number is set to 1. The compressor stops when there is
only a heating requirement.
If the calculated flow temperature drops below the calcu-
lated 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 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
Default value: 10 °C
Menu 9.3.13 [S] Diff HP add. heat
If additional heat is permitted (menu 8.2.1) and the current
flow line temperature falls below the calculated set value
plus the value from menu 9.3.12, the degree minute value
is to the value in menu 9.2.1 plus 1 until the compressor
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 addition is permitted. This means that
the addition can cut in immediately.
Setting range: 1 – 8 °C
Default value: 3 °C
Menu 9.3.14 [S] Block HW/Heating
If heating or hot water are not required, they can be
deselected here.
Operating mode Hot water or Only addition must be selec-
ted if heating is deselected.
Setting range: No HW, No heating, HW+Heating
Default value: HW+Heating
Menu 9.3.15 [S] Heat drop at alarm
Here you select whether heat production is to be reduced
in the event of an alarm.
Setting range: Yes, No
Default value: Yes
Menu 9.3.16 [S] Type of HW sensor
Here you can select whether to use hot water sensors that
manage higher temperatures (above 90 °C) or not.
Standard: Standard setting
High temp: Calculation for HW jacket sensor (BT6), Addi-
tion sensor (BT19) as well as supply sensor (BT2) arere-
placed 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
62
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
