NOTE
For wall mounting, use screws (and any plugs)
suitable for the surface.
Use all mounting points and install SMO S40 upright flat
against the wall without any part of the control module
protruding beyond the edge of the wall.
Leave at least 100 mm free space around the control
module to facilitate access and cable routing on installa-
tion and service.
Caution
Screws for removing the front cover are
reached from underneath.

General
Pipe installation must be carried out in accordance with
applicable regulations. See manual for compatible NIBE
air/water heat pump for installation of the heat pump.
The pipe dimension should not be less than the recom-
mended pipe diameter according to the table. However,
each system must be dimensioned individually to man-
age the recommended system flows.
MINIMUM SYSTEM FLOWS
The installation must be dimensioned at least to manage
the minimum defrosting flow at 100% pump operation,
see table.

The temperature sensors are mounted with heat con-
ducting paste, cable ties (the first cable tie is secured
to the pipe in the middle of the sensor and the other
cable tie is mounted approx. 5 cm beyond the sensor)
and aluminium tape. Then insulate with supplied insula-
tion tape.
NOTE
Sensor and communication cables must not
be placed near power cables.
Fixed condensing
If SMO S40 is only to work towards a water heater with
fixed condensing, you must connect external supply
temperature sensor (BT25) according to the description
in section "Temperature sensor, external flow line". In
addition, you must make the following menu settings.

ations may be required)

Connecting air/water
heat pump
You can find a list of compatible air/water heat pumps
in section "System solutions".
• Install the necessary safety equipment, non-return
valve, shut-off valve, circulation pump and expansion
vessel. Also, consult the Installer Manual for your
air/water heat pump.
• Install the enclosed filterball.
• If the system is to work towards both a climate sys-
tem and hot water heater, a reversing valve must be
installed.

Connecting the
climate system
A climate system is a system that regulates indoor
comfort with the help of the control system in SMO S40
and for example radiators, underfloor heating/cooling,
fan convectors etc.
• Install external supply temperature sensor (BT25) It
says when the air/water heat pump must start to
produce heating/cooling for the climate system.
• Install external return temperature sensor (BT71). It
is used to check that the climate system is correctly
adjusted.
• When connecting to systems with thermostats on all
radiators/underfloor heating coils, some of the thermo-
stats must be removed to ensure there is sufficient
flow.
• For an even flow to the radiators during hot water
charging or similar, a circulation pump and reversing
valve for the climate system are installed.

Cold and hot water
CONNECTING THE HOT WATER HEATER
• Controlling hot water sensor (BT6) and display hot
water sensor (BT7) are placed in the water heater.
• Fit shut-off valve, non-return valve and safety valve as
illustrated.
• The safety valve must have max. 1.0 MPa (10.0 bar)
opening pressure, and be installed on the incoming
domestic water line as shown.
• A mixer valve must also be installed, if the factory
setting for hot water is changed. National regulations
must be observed.
• Hot water production is activated in the start guide or
in menu 7.1.1.

XL2
Installation alternative
SMO S40 can be connected in several different ways,
some of which are shown below.
More information about the alternatives is available at
nibe.eu/ODM and in the relevant assembly instructions
for the accessories used. See section "Accessories" for
a list of the accessories that can be used with SMO S40.
BUFFER VESSEL UKV
UKV is an accumulator tank that is suitable for connec-
tion 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.
The image shows UKV flow equalisation.
ADDITION
On cold days of the year, when the availability of energy
from the air is lower, the additional heating can com-
pensate and help to produce heat. The additional heating
is also good to have as assistance, if the heat pump
ends up outside its working range or if it has been
blocked for any reason.
In the principle diagram below, the additional heat is
located after the reversing valve. (Additional heat can
also be connected before the reversing valve.)
COOLING
Cooling (in 2-pipe system)
Cooling and heating are distributed via the same climate
system.
NIBE SMO S40Chapter 4 | Installing the installation16

Cooling (in 4-pipe system)
With the accessory NIBE AXC 30, separate cooling and
heating systems can be connected via a reversing valve.
It is also possible to connect cooling (in 4 pipe systems)
on AUX10 (relay K8) or AUX11 (relay K9).
-EP45-GP10
-EP45
-EQ1-BT64
EXTRA CLIMATE SYSTEM
In buildings with several climate systems that require
different supply temperatures, the accessory
ECS 40/ECS 41 can be connected. A shunt valve then
lowers the temperature to the underfloor heating sys-
tem, for example.

17Chapter 4 | Installing the installationNIBE SMO S40

General
• Disconnect SMO S40 before insulation testing the
house wiring.
• When the building is equipped with an earth-fault
breaker the heat pump should be equipped with a
separate one.
• SMO S40 must be installed via an isolator switch. The
cable area has to be dimensioned based on the fuse
rating used.
•Use a screened cable for communication with the heat
pump.
• To prevent interference, sensor cables to external
connections must not be laid close to high voltage
cables.
• The minimum area of communication and sensor
cables to external connections must be 0.5 mm² up
to 50 m, for example EKKX, LiYY or equivalent.
• When cable routing in SMO S40, the cable grommets
(UB1 and UB2) must be used.
•For an electrical wiring diagram for the control module,
see section "Technical Specifications"

NOTE
Do not start the system before filling up with
water. Components in the system could be
damaged.
NOTE
Electrical installation and any servicing must
be carried out under the supervision of a quali-
fied electrician. Disconnect the current using
the circuit breaker before carrying out any ser-
vicing.
Electrical installation and wiring must be carried out in
accordance with the stipulations in force.

Compressor blocking must be performed either on the
control module or on the air/water heat pump, not on
both at the same time.

CHARGE PUMP FOR HEAT PUMP 1 AND 2
Connect circulation pump (AA35-GP12.1-EB101) to the
terminal block AA100-X2 (PE), AA100-X3 (N) and AA100-
X5:3 (230 V).
Control signal for AA35-GP12.1-EB101 is connected to
terminal block AA100-X12:1 (Pulse/0–10V) (PWM1) and
GND on any block X13.
If two heat pumps are connected to SMO S40 the circu-
lation pump (AA35-GP12.2-EB102) must be connected
to the terminal block AA100-X2 (PE), AA100-X3 (N) and
AA100-X5:4 (230 V). Control signal for (AA35-GP12.2-
EB102) is connected to terminal block AA100-X12:3
(Pulse/0–10V) (PWM0) and GND on any block X13.
TIP
Two charge pumps can be connected to and
controlled by SMO S40. Several charge pumps
can be connected, if accessory boards (AXC)
are used, two pumps per board.
