Caution
A slow climate system, such as underfloor
heating, may be unsuitable for controlling with
room sensors.
Setting the temperature (without room sensors
activated):
Setting range: -10 to +10
The display shows the set value for heating/cooling
(curve offset). To increase or reduce the indoor temper-
ature, increase or reduce the value in the display.
The number of steps the value has to be changed in
order to achieve a one degree change to the indoor
temperature depends on the climate system. One step
is usually enough, but in some cases several steps may
be required.
Set the desired value. The new value is shown on the
right-hand side of the symbol on home screen heat-
ing/home screen cooling.
Caution
An increase in the room temperature can be
slowed by the thermostats for the radiators or
under floor heating. Therefore, open the ther-
mostats fully, except in those rooms where a
cooler temperature is required, e.g. bedrooms.
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 in menu
1.30.1 by one increment.
If it is cold outdoors and the room temperature
is too high, reduce the curve slope in menu
1.30.1 by one increment.
If it is warm outdoors and the room temperat-
ure is too low, increase the value in menu 1.1.1
by one increment.
If it is warm outdoors and the room temperat-
ure is too high, reduce the value in menu 1.1.1
by one increment.

MENU 1.3 - ROOM SENSOR SETTINGS
Name room sensor
Setting range: a-z
Control room sensor
Setting range: on/off
Coefficient of performance system
Setting range: 0.0 - 6.0
Cooling factor system
Setting range: 0.0 - 6.0
Activate room sensors to control the room temperature
here.
You can connect up to four room sensors to each cli-
mate system, and you can give each sensor a unique
name.
The sensor in each climate system that is furthest from
the set temperature has control; S1155PC tries to keep
the temperature up in the room whose sensor is furthest
from the set value.
Caution
A slow heating system such as underfloor
heating may be inappropriate for controlling
with room sensors.
Factor system
Caution
Too high a set value for "factor system" can
result in an uneven room temperature.
If several climate systems are installed the above set-
tings can be made for the relevant systems.
MENU 1.5 - CLIMATE SYSTEM NAME
You can give the installation's climate system a name
here.
MENU 1.30 - ADVANCED
Menu advanced is intended for the advanced user. This
menu has several sub-menus.
Curve, heating Setting the heating curve slope.
Curve, cooling Setting the curve slope for cooling.
External adjustment Setting the heating curve offset
when an external contact is connected.
Lowest supply heating
supply temperature during heating operation.
Lowest supply cooling Setting minimum permitted
supply temperature when cooling.
Highest supply heating
supply temperature for the climate system.
