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
Depending on which accessory is used the setting range
can vary.
MENU 7.1.2.7 - PUMP SPEED BRINE
Make settings for the brine pump's speed here.
Speed in passive cooling
Setting range: 1 - 100 %
Speed in passive cooling
: Here you set the speed at
which the brine pump will operate during passive cool-
ing.
MENU 7.1.7 - COOLING
This menu contains sub-menus where you can make
advanced settings for cooling operation.
MENU 7.1.7.2 - HUMIDITY CONTROL
Only shown if a moisture sensor is installed and cooling
is activated.
Prevent condensation in cold
Setting range: on/off
Limit RH in cold
Setting range: on/off
Prevent condensation in cold:
With the function activ-
ated, condensation in the pipes is prevented.
Limit RH in cold:
With the function activated, the tem-
perature is regulated to achieve the desired relative hu-
midity (RH).
MENU 7.1.7.3 - SYSTEM SETTINGS COOLING
Shunt amplification
Setting range: 0,1 - 1,0
Shunt waiting time
Setting range: 10 - 300 seconds
Shunt amplification and shunt waiting time
: Here, you
set shunt amplification and shunt wait time for the
cooling system.
MENU 7.1.10.2 - AUTO MODE SETTING
Start cooling
Setting range: -20 – 40°C
Filtering time
Setting range: 0 – 48 h
Used as cooling/heating sensor
Possible options: None, Zone 1 - X
Set point value cool/heat sensor
Setting range: 5 – 40 °C
Heating at subnormal room temp
Setting range: 0,5 – 10,0 °C
Cooling at excess room temp
Setting range: 0,5 – 10,0 °C
Auto:
When the operating mode is set to "Auto", the in-
stallation selects when start and stop of additional heat
and cooling/heat production are permitted, depending
on the average outdoor temperature.
Filtering time
: You can set the time over which the aver-
age outdoor temperature is calculated. If you select 0,
the current outdoor temperature is used.
Used as cooling/heating sensor
Here you select the sensor that will be used for cool-
ing/heating. If BT74 is installed, it will be preselected
and no other option is possible.
Set point value cool/heat sensor
: Here, you can set the
indoor temperature at which the installation will change
between heating and cooling operation.
Heating at subnormal room temp
: Here, you can set
how much the room temperature can drop below the
desired temperature before the installation switches to
heating operation.
Cooling at excess room temp
: Here, you can set how
much the room temperature can increase above the
desired temperature before the installation switches to
cooling operation.
