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 heating.
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
Activate room sensors to control the room temperature
here.
You can connect up to four room sensors to each zone,
and you can give each room sensor a unique name.
The room sensor in each climate system that is furthest
from the set temperature has control; S1155 tries to
keep the temperature up in the room whose sensor is
furthest from the set value.
40 Chapter 9 | Control - Menus
Caution
A slow heating system such as underfloor
heating may be inappropriate for controlling
with room sensors.
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.
External adjustment Setting the heating curve offset
when an external contact is connected.
Lowest supply heating
supply temperature during heating operation.
Highest supply heating
supply temperature for the climate system.
Own curve You can create your own heating curve
here, if there are special requirements, by setting the
desired supply temperatures for different outdoor tem-
peratures.
Point offset 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.
MENU 1.30.1 - CURVE, HEATING
Curve, heating
Setting range: 0 - 15,0
In menu "Curve, heating" you can view the heating curve
for your house. The task of the heating curve is to
provide an even indoor temperature, regardless of the
outdoor temperature. It is from this heating curve that
S1155 determines the temperature of the water to the
climate system, the supply temperature, and therefore
the indoor temperature. Here, you can select heating
curve and read off how the supply temperature changes
at different outdoor temperatures.
TIP
It is also possible to create your own curve.
This is done in menu 1.30.7.
