Here you set the maximum permitted difference
between the calculated and actual supply temperature
during compressor respectively add. heat mode. Max
diff. additional heat can never exceed max diff. com-
pressor
max diff compressor
When the current supply temperature deviates from
the set value compared to that calculated, the heat pump
is forced to stop irrespective of the degree-minute value.
If the current supply temperature exceeds the calculated
flow with set value, the degree minute value is set to 0.
The compressor in the heat pump stops when there is
only a heating demand.
max diff addition
If "addition" is selected and activated in menu 4.2 and
the present supply temp exceeds the calculated with
set value, the additional heat is forced to stop.
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
max brine in
Setting range: 10 – 30 °C
Default value: 20 °C
NIBE F1145
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.
max brine in
Set the temperature at which the heat pump is to activ-
ate the alarm for high temperature in incoming brine.
Select "alarm activated" to activate the alarm.
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.
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 sys-
tem.
