If there is more than one climate system the setting can
be made separately for each system.
MENU 1.30.5 - LOWEST SUPPLY COOLING
cooling
Depending on which cooling accessory is used, the
setting range can vary.
Setting range 7 – 30 °C
Alarm, room sensor during cooling operation
Setting range: on/off
Set the minimum temperature on the supply temperat-
ure to the climate system. This means that S1155PC
never calculates a temperature lower than that set here.
If there is more than one climate system the setting can
be made separately for each system.
Here, you can receive alarms during cooling operation,
for example if a room sensor malfunctions.
NOTE
Cooling flow line must be set with regard to
which climate system is connected. For ex-
ample, floor cooling with too low cooling flow
line can cause condensation precipitation,
which in the worst instance could lead to
moisture damage.
MENU 1.30.6 - HIGHEST SUPPLY HEATING
climate system
Setting range: 5 - 80°C
Here, you set the highest supply temperature for the
climate system. This means that S1155PC never calcu-
lates a temperature higher than the one set here. If the
installation has multiple climate systems, the highest
supply temperature can be set for each system. Climate
systems 2 – 8 cannot be set to a higher max supply
temperature than climate system 1.
Caution
With underfloor heating systems, "Maximum
supply temperature for heating" should nor-
mally be set between 35 and 45°C.
Check the max floor temperature with your
floor supplier.

MENU 1.30.7 - OWN CURVE
Own curve, heating
Caution
Curve 0 must be selected for own curve to
apply.
You can create your own heating curve here, if there
are special requirements, by setting the desired supply
temperatures for different outdoor temperatures.
Supply temp
Setting range: 5 – 80 °C
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 1.30.8 - POINT OFFSET
Outdoor temp. point
Setting range: -40 – 30 °C
Change in curve
Setting range: -10 – 10 °C
Select a change in the heating curve at a certain outdoor
temperature here. One step is usually enough to change
the room temperature by one degree, but in some cases
several steps may be required.
The heating curve is affected at ± 5°C from set outdoor
temp. point.
It is important that the correct heating curve is selected
so that the room temperature is experienced as even.
TIP
If it feels cold in the house at e.g. -2°C, "out-
door temp. point" is set to "-2" and "change in
curve" is increased until the desired room
temperature is maintained.
