Nibe PCS 44 Installer Manual page 25

In menu "Curve, cooling" you can view the cooling curve
for you house. The task of the cooling curve is, together
with the heating curve, to give an even indoor temper-
ature, regardless of the outdoor temperature, and
thereby energy-efficient operation. It is from these
curves that the installation determines the temperature
of the water to the heating system, the supply temper-
ature, and therefore the indoor temperature. Here, select
the curve and read how the supply temperature changes
at different outdoor temperatures. The number to the
right of "system" shows which system you have selected
the curve for.
Caution
Must be restricted with underfloor cooling min.
flow line temp. to prevent condensation.
MENU 1.30.7 - OWN CURVE
Own curve, cooling
Caution
Curve 0 must be selected for own curve to
apply.
You can create your own cooling curve here, if there are
special requirements, by setting the desired supply
temperatures for different outdoor temperatures.
Supply temp
Setting range: -5 – 40 °C
MENU 7.1.2.2 - PUMP SPEED HEATING
MEDIUM GP1
Make settings here for the heating medium pump's
speed in the current operating mode, for example in
heating or hot water operation. Which operating modes
can be changed depends on which accessories are
connected.
Heating, auto
Alternative: on/off
Heating, manual
Setting range: 1 - 100 %
Minimum permitted speed
Setting range: 1 - 50 %
Speed in standby mode
Setting range: 1 - 100 %
Highest permitted speed
Setting range: 50- 100%
Heating, auto: Here, you set whether the heating medi-
um pump is to be regulated automatically or manually.
PCS 44 | GB
Heating, manual: If you have opted to control the heating
medium pump manually, you set the desired pump
speed here.
Minimum permitted speed: Here you can restrict the
pump speed so that the heating medium pump is not
allowed to operate at a lower speed than the set value.
Speed in standby mode: The speed the heating medium
pump is to have in standby mode is set here. Standby
mode occurs when heating or cooling operation is per-
mitted at the same time as there is no need for either
compressor operation or electric additional heat.
Speed during active cooling: Here, you set the desired
pump speed for active cooling.
Maximum permitted speed: Here you can restrict the
pump speed so that the heating medium pump is not
allowed to operate at a higher speed than the set value.
MENU 7.1.2.7 - PUMP SPEED BRINE
Make settings for the brine pump's speed here.
Operating status
Setting range: Fixed delta, Auto, manual
Manual
Setting range: 1 - 100 %
Speed in passive cooling
Setting range: 1 - 100 %
Speed in standby mode, cooling
Setting range: 0 - 100 %
Operating mode: Here you set whether the brine pump
is to be regulated automatically, manually or with fixed
delta.
Fixed delta: Here you set whether the brine pump will
be controlled with fixed delta, e.g. for ground water
systems.
Manual: If you have opted to control the brine pump
manually, you set the desired pump speed here.
Speed in passive cooling: Here you set the speed at
which the brine pump is to operate during passive
cooling.
Speed in standby mode, cooling: Here, you set the
speed at which the brine pump is to operate in standby
mode when passive cooling is permitted.
