MENU 1.3.4 - ZONES
Here, you add and name zones. You also select the climate
system to which a zone is to belong.
MENU 1.3.30 - UNASSIGNED UNITS
All units that are not connected to a zone are listed here.
MENU1.4 - EXTERNAL INFLUENCE
Information for the accessories/functions that can affect
the indoor climate and that are active is shown here.
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
the external contact is connected.
"Lowest supply heating" Setting minimum permitted supply
temperature during heating operation.
"Highest supply heat" Setting maximum permitted 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 temperatures.
"Point offset" Select a change in the heating curve at a cer-
tain 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
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 S735 determ-
ines the temperature of the water to the climate system,
the supply temperature, and therefore the indoor temperat-
ure. Here, you can select heating curve and read off how
the supply temperature changes at different outdoor tem-
peratures.
TIP
It is also possible to create your own curve. This
is done in menu 1.30.7.
Caution
With underfloor heating systems, the maximum
supply temperature is normally set between 35
and 45 °C.
TIP
If the room temperature is constantly too low/high,
you increase/decrease the curve offset by one
step.
If the room temperature changes when the out-
door temperature changes, you increase/decrease
the curve slope by one step.
Wait 24 hours before making a new setting, so that
the room temperature has time to stabilise.
MENU 1.30.3 - EXTERNAL ADJUSTMENT
Climate system
Setting range: -10 – 10
Setting range (if room sensor is installed): 5 – 30 °C
Connecting an external contact, for example, a room ther-
mostat or a timer allows you to temporarily or periodically
raise or lower the room temperature. When the contact is
on, the heat curve offset is changed by the number of steps
selected in the menu. If a room sensor is installed and activ-
ated the desired room temperature (°C) is set.
If there is more than one climate system, the setting can be
made separately for each system and zone.
MENU 1.30.4 - LOWEST SUPPLY HEATING
heating
Setting range: 20 – 80 °C
Set the minimum temperature on the supply temperature
to the climate system. This means that S735 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.
MENU 1.30.6 - HIGHEST SUPPLY HEAT
climate system
Setting range: 20 – 80 °C
Here, you set the highest supply temperature for the climate
system. This means that S735 never calculates a temperat-
ure higher than the one set here.
If there is more than one climate system the setting can be
made separately for each system. Climate systems 2 – 8
cannot be set to a higher max supply temperature than cli-
mate system 1.
