cooling settings Settings for cooling.
fan return time Fan return time settings in the event
of temporary ventilation speed change.
own curve Setting own curve for heating and cooling.
point offset Setting the offset of the heating curve or
cooling curve at a specific outdoor temperature.
night cooling Setting night cooling.
MENU 1.9.1 - CURVE
heating curve
Setting range: 0 – 15
Default value: 9
cooling curve (accessory required)
Setting range: 0 – 9
Default value: 0
You can select heating or cooling in the curve menu.
The next menu (heating curve/cooling curve) shows the
heating and cooling curves for your house. The task of
the curve is to give an even indoor temperature, regard-
less of the outdoor temperature, and thereby energy
efficient operation. It is from these heat curves that the
heat pump’s control computer determines the temper-
ature of the water to the system, the supply temperat-
ure, and therefore the indoor temperature. Select the
curve and read off how the supply temperature changes
at different outdoor temperatures here. The number to
the far right of "system" displays which system you have
selected the heating curve/cooling curve for.
Caution
With underfloor heating systems, max flow
line temperature should normally be set to
between 35 and 45 °C.
With underfloor cooling, "min. flow line temp."
must be restricted to prevent condensation.
Check the max temperature for your floor with
your installer/floor supplier.
TIP
Wait 24 hours before making a new setting,
so that the room temperature has time to sta-
bilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope by one in-
crement.
If it is cold outdoors and the room temperature
is too high, lower the curve slope by one incre-
ment.
If it is warm outdoors and the room temperat-
ure is too low, increase the curve offset by one
increment.
If it is warm outdoors and the room temperat-
ure is too high, lower the curve offset by one
increment.
MENU 1.9.2 - EXTERNAL ADJUSTMENT
heating
climate system
Setting range: -10 to +10.
Default value: 0
cooling (accessory is required)
climate system
Setting range: -10 to +10.
Default value: 0
Connecting an external switch, for example a room
thermostat or a timer, allows you to raise or lower the
room temperature temporarily or periodically. When the
switch is turned on, the heating curve or cooling curve
offset is changed by the number of steps selected in
the menu. If a room sensor is installed and activated,
the desired room temperature (°C) is set.
If there is more than one climate system the setting can
be made separately for each system.
MENU 1.9.3 - MIN. FLOW LINE TEMP.
heating
Setting range: 5-70 °C
Default value: 20 °C
cooling (accessory required)
Depending on which accessory is used the setting
range can vary.
Factory setting: 18 °C
