Menu 5.1.4 - alarm actions
Select how you want the heat pump to alert you that
there is an alarm in the display here.
The different alternatives are that the heat pump stops
producing hot water (default setting) and/or reduces
the room temperature.
Caution
If no alarm action is selected, it can result in
higher energy consumption in the event of an
alarm.
Menu 5.1.5 - fan sp. exhaust air (accessory is
required)
normal and speed 1-4
Setting range: 0 – 100 %
Set the speed for the five different selectable speeds for
the fan here.
Caution
An incorrectly set ventilation flow can damage
the house and may also increase energy con-
sumption.
Menu 5.1.7 - br pmp al set.
min. brine out
Setting range: -12 – 15 °C
Default value: -8 °C
min. brine out
Set the temperature at which the heat pump is to activ-
ate the alarm for low temperature in outgoing brine.
If "automatic reset" is selected, the alarm resets when
the temperature has increased by 1 °C below the set
value.
The compressor winds down when the brine temperat-
ure reaches the set minimum value for brine temperat-
ure. Compressor control attempts to maintain the brine
at a temperature 2 ° greater than the set value for brine
out.
Menu 5.1.8 - operating mode brine pump
op. mode
Setting range: intermittent, continuous, 10 days con-
tinuous
Default value: intermittent
Set the operating mode of the brine pump here.
intermittent: The brine pump starts approx. 20 seconds
before and stops approx.20 seconds after the com-
pressor.
continuous: Continuous operation.
NIBE F1155
10 days continuous: Continuous operation for 10 days.
Then the pump shifts to intermittent operation.
TIP
You can use "10 days continuous" at start-up
to obtain continuous circulation during a start-
up time in order to make it easier to bleed the
system.
Menu 5.1.9 - brine pump speed
op. mode
Setting range: auto / manual / fixed delta
Default value: auto
delta T
Setting range: 2 - 10 °C
Factory setting: 4 °C

Setting range: 1 - 100 %
Factory setting: 70 %
speed passive cooling (accessory is required)
Setting range: 1 - 100 %
Factory setting: 100 %
Set the speed of the brine pump here. Select "auto" if
the speed of the brine pump is to be regulated automat-
ically (factory setting) for optimal operation.
For manual operation of the brine pump deactivate
"auto" and set the value to between 1 and 100%.
For operation of brine pump with "fixed delta", select
"fixed delta" under "op. mode" and set the value
between 2 and 10 °C.
If there are accessories for cooling present or if the heat
pump has a built-in function for cooling you can also set
the brine pump speed during passive cooling operation
(the brine pump then runs in manual operation).
If the continuous operating mode (see "Menu 5.1.8 -
operating mode brine pump", page 45) has been selec-
ted one can also choose waiting mode. The circulation
pump continues to run while the compressor stops.
