Climate system
A climate system is a system that regulates the indoor
temperature with the help of the control system in S1155PC
and, for example, radiators, underfloor heating, underfloor
cooling, fan coils, etc.
CONNECTING THE CLIMATE SYSTEM
Install as follows:
• expansion vessel
• pressure gauge
• pressure relief valve
Recommended opening pressure is 0.25 MPa (2.5 bar).
For information about max opening pressure, see technical
data. Install the safety valve as illustrated.
• enclosed filterball (QZ2)
Install the filterball as close to S1155PC as possible.
• shut-off valve
Install the shut-off valve as close to S1155PC as possible.
• When connecting to a system with thermostats on all ra-
diators/underfloor heating coils, either a bypass valve
must be fitted or some of the thermostats must be re-
moved to ensure there is sufficient flow and heat emission.

Cold and hot water
Hot water production is activated in the start guide or in
menu 7.1.1 - "Hot water".
NOTE
If S1155PC is not docked to a water heater, the
connection for the water heater (XL9) must be
plugged.
CONNECTING THE HOT WATER HEATER
Install as follows:
• controlling hot water sensor (BT6)
The sensor is placed in the middle of the water heater.
• displayed hot water sensor (BT7)
1
The sensor is optional and is placed in the top of the water
heater.
• shut-off valve
• non-return valve
• pressure relief valve
The safety valve must have a maximum 1.0 MPa (10.0 bar)
opening pressure and be installed on the incoming domest-
ic water line as shown.
• mixing valve
A mixer valve must also be installed, if the factory setting
for hot water is changed. National regulations must be
observed.
1 The sensor is factory fitted on some water heater/accumulator
tank models from NIBE.

Installation alternative
S1155PC can be installed in several different ways, some of
which are shown here.
Further option information is available at nibe.eu and in the
respective assembly instructions for the accessories used.
See
page 64 for a list of the accessories that can be used
with S1155PC.
BUFFER VESSEL UKV
UKV is an accumulator tank that is suitable for connection
to a heat pump or another external heat source, and can
have several different applications. It can also be used during
external control of the heating system.
If the climate system volume is too small for the heat pump
output, the radiator system can be supplemented with a
buffer vessel, for example NIBE UKV.
