current norms and directives. See manual for compatible
NIBE air/water heat pump for installation of the heat
pump.
Compatible NIBE air/water heat
pumps
Compatible NIBE air/water heat pumps must be
equipped with a control card that has at least the soft-
ware version given in the following list. The control card
version is displayed in the heat pump's display (if applic-
able) upon start-up.

Temperature sensor installation
on pipe
LEK
LEK
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 insulation
tape.
NOTE
Sensor and communication cables must not be
placed near power cables.
Docking alternatives
SMO 40 can be connected with other products from
NIBE in several different ways, some of which are shown
below (accessories may be required).
Further option information is available at www.nibe.eu
and in the respective assembly instructions for the ac-
cessories used. See page 54 for a list of the accessories
that can be used with SMO 40.
Installations with SMO 40 can produce heating and hot
water. Cooling can also be produced, depending on
which heat pump is used.
On cold days of the year when the access to energy from
the air is reduced the additional heating can compensate
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.
NOTE
The heating medium side and the hot water
side must be fitted with the necessary safety
equipment in accordance with the applicable
regulations.
This is the outline diagram. Actual installations
must be planned according to applicable
standards.

This installation alternative is suitable for simpler install-
ations with a focus on low installation costs.
SMO 40 (AA25) starts and stops the heat pump (EB101)
to meet the heat and hot water demand of the installa-
tion. At simultaneous heating and hot water demand
the reversing valve switches (AA25-QN10) periodically
between the climate system and the water heater/accu-
mulator tank (CP10). When the hot water heater/accu-
mulator tank is fully charged (CP10), the reversing valve
switches (AA25-QN10) to the climate system.
Additional heat (EB1) is connected automatically when
the power demand for the installation exceeds the heat
pump capacity. This is used for both heating and char-
ging hot water.
The additional heat can also be used if a higher temper-
ature in the hot water is required than the heat pump
can produce.

NOTE

This installations alternative is suitable for more complex
installations with a focus on comfort.
SMO 40 (AA25) starts and stops the heat pump (EB101)
to meet the heat and hot water demand of the installa-
tion. At simultaneous heating and hot water demand
the reversing valve switches (AA25-QN10) periodically
between the climate system and the water heater/accu-
mulator tank (CP10). When the water heater/accumulat-
or tank is fully charged (CP10), the reversing valve
switches (AA25-QN10) to the climate system and pool.
When the pool needs heating the reversing valve (CL11-
QN19) switches from the climate system to the pool
system.
Additional heat (EB1) is connected automatically when
the energy demand exceeds the heat pump capacity.
Immersion heater (EB20) in the water heater/accumulat-
or tank (CP10) is used during the time to produce hot
water if the heat pump (EB101) is used for heating the
building at the same time.
The immersion heater (EB20) can also be used if a higher
temperature of hot water is required than the heat pump
can produce.
During cooling operation (requires compatible heat
pump), the reversing valve (EQ1-QN12) switches to the
cooling system (EQ1). If several demands occur while
there is a cooling demand, the installation reacts differ-
ently. In event of a hot water demand, the reversing valve
(EQ1-QN12) switches back and hot water is produced
until the demand is fulfilled. In event of a heating de-
mand, the reversing valve (EQ1-QN12) instead switches
periodically between the demands. When the cooling
demand is met, the reversing valve switches back to basic
mode (heat/hot water).
Active cooling (in 4-pipe system) is selected in menu 5.4
- soft in/outputs.

NOTE
NIBE does not supply all components in this
outline diagram.
NOTE
Different types of demand (heating, hot water
etc.) mean different supply and return temper-
atures as well as different flows to the heat
pump.
When connecting pipes in installations with
several compressors and different heating de-
mands, ensure that these are separated so that
different return temperatures are not mixed.
Otherwise this can affect the heating installa-
tion's efficiency.
See outline diagram for example.
This installations alternative is suitable for more complex
installations with a focus on comfort.
SMO 40 (AA25) starts and stops the heat pumps EB101)
and (EB102) to meet the heat and hot water demand of
the installation. The heat pump (EB103) is used for
heating and pool heating and heat pump (EB104) is used
for cooling, heating and pool heating.
At simultaneous heating and hot water demand the re-
versing valve switches (AA25-QN10) periodically between
the climate system and the water heater/accumulator
tank (CP10). When the hot water heater/accumulator
tank is fully charged (CP10), the reversing valve switches
(AA25-QN10) to the climate systems. When the pool
needs heating the reversing valve (CL11-QN19) or (CL12-
QN19) switches from the climate system to the pool
system.
Additional heat (EB1) is connected automatically when
the energy demand exceeds the heat pump capacity.
Additional water heating is obtained from the additional
water heater (EB10).
During cooling operation (requires compatible heat
pump), the reversing valve (EQ1-QN12) switches to the
cooling system (EQ1). If several demands occur while
there is a cooling demand, the installation reacts differ-
ently. In the event of a heating demand, the reversing
valve (EQ1-QN12) instead switches periodically between
the demands. When the cooling demand is met, the re-
versing valve switches back to basic mode (heat/hot
water). In the event of a pool heating demand, the re-
versing valve (EQ1-QN12) switches back at the same time
as the reversing valve (CL12-QN19) switches to the pool
system (CL12) and pool heating is produced until the
demand is fulfilled.
SMO 40Chapter 4 | Pipe connections14

General
■Disconnect SMO 40 before insulation testing the house
wiring.
■If the building is equipped with an earth-fault breaker,
SMO 40 should be equipped with a separate one.
■SMO 40 must be installed via a circuit breaker with a
minimum breaking gap of 3 mm.
■For the electrical wiring diagram for the control mod-
ule, see page .60.
■Use a screened three core cable for communication
with the heat pump.
■Communication and sensor cables to external connec-
tions must not be laid close to high current 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 into SMO 40, cable grommets
(UB1 and UB2, marked in image) must be used.
NOTE
The switch (SF1) must not be moved to "" or
" " until the boiler in the system has been
filled with water. The compressor in the heat
pump and any external additional heat can be
damaged.
NOTE
Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician. Cut the current with the circuit
breaker before carrying out any servicing.
Electrical installation and wiring must be car-
ried out in accordance with the stipulations in
force.
When installing SMO 40, NIBE's air/water heat
pump and any addition must be current free.
NOTE
See outline diagram for your system for physic-
al location of the temperature sensor that is to
be installed.
Caution
The relay outputs on the accessory board (AA5)
may be subjected to a max load of 2 A (230 V)
in total.

(AA3) as illustrated.
If two heat pumps are connected to SMO 40, the circula-
tion pump (EB102-GP12) must be connected to terminal
block X4:12 (PE), X4:13 (N) and X4:15 (230 V) on the

TIP
Two charge pumps (four if the internal accessor-
ies card is used) can be connected to and con-
trolled by SMO 40. More charge pumps can be
connected if the accessories card is used, two
pumps per card.
