Nibe S1155 Installer Manual page 41

Caution
With underfloor heating systems, the maxim-
um supply temperature is normally set
between 35 and 45 °C.
Check the max floor temperature with your
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 1.30.3 - EXTERNAL ADJUSTMENT
Climate system
Setting range: -10 to +10
Setting range (if room sensor is installed): 5 - 30°C
Connecting an external contact, for example, a room
thermostat or a timer allows you to temporarily or peri-
odically 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 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 1.30.4 - LOWEST SUPPLY HEATING
heating
Setting range: 5 - 80 °C
Set the minimum temperature on the supply temperat-
ure to the climate system. This means that S1155 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.
NIBE S1155
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 S1155 never calculates
a temperature higher than the one set here. If the install-
ation has multiple climate systems, the highest supply
temperature can be set for each system. Climate sys-
tems 2 – 8 cannot be set to a higher max supply temper-
ature 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
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.
