Common electrical
connection
NOTE
All electrical connections must be carried out
by an authorised electrician.
Electrical installation and wiring must be carried
out in accordance with the stipulations in force.
The main product must be disconnected from
the power supply when installing AXC 30.
• 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.
• AXC 30 must be installed via an isolator switch. The
cable area has to be dimensioned based on the fuse
rating used.
• Mark the relevant electrical cabinet with a warning
about external voltage, in those cases where a com-
ponent in the cabinet has a separate supply.
• AXC 30 restarts after a power failure.
Electrical circuit diagrams are at the end of the chapter
for each connection option.
CABLE LOCK
Use a suitable tool to release/lock cables in terminal
blocks.

MOUNTING
The AXC module (AA25) is a separate, electric control
module and must be mounted on a wall.
Caution
The screw type must be adapted to the surface
on which installation is taking place.
UN
Use all mounting points and mount the module upright,
flat against the wall.
Leave at least 100 mm of free space around the module
to allow access and make cable routing easier during
installation and servicing.
NOTE
The installation must be carried out in such a
way that IP21 is satisfied.

CONNECTING COMMUNICATION
AXC 30 contains an accessory board (AA5) that connects
directly to the control module on its joint board (terminal
block AA100-X9).
If more accessories are to be connected, or are already
installed, the boards are connected in series.
AXC 30 S-series | GB6

Because there can be different connections for accessor-
ies with accessory board (AA5), you should always read
the instructions in the manual for the accessory that is
to be installed.

Shunt controlled
additional heat
GENERAL
This function enables an external additional heater, e.g.
an electric boiler, wood boiler, pellet boiler, oil boiler,
gas boiler or district heating, to assist with the heating.
The indoor module controls a shunt valve (EM1-QN11)
and a circulation pump (EM1-GP10) via the accessory
board in AXC 30. If the heat pump cannot maintain the
correct supply temperature, at the external supply tem-
perature sensor, (EM1-BT25), the additional heat starts.
When the boiler temperature on the boiler sensor (EM1-
BT52) exceeds the set value, the indoor module trans-
mits a signal to the shunt (EM1-QN11) to open from the
additional heat. The shunt (EM1-QN11) is regulated so
the true supply temperature corresponds with the indoor
module’s theoretical calculated set point value. When
the heating demand drops sufficiently, so that additional
heat is no longer required, the shunt (EM1-QN11) closes
completely.
Factory-set minimum operating time for the boiler is 12
hours.
The function smart energy source can be selected if you
want to prioritise automatically between heat pump
operation and additional heat versus the best price or
environmental impact.
PIPE CONNECTIONS
The external circulation pump (EM1-GP10) is placed on
the supply line to the climate system after the temper-
ature sensor (AA35-BT25).
SHUNT VALVE
The shunt valve (EM1-QN11) must be placed on the
supply line to the climate system after the heat pump
according to the outline diagram.

• Connect the supply line from the external additional
heat to the shunt valve to port A (opens on increase
signal).
TEMPERATURE SENSOR
• Install the boiler sensor (EM1-BT52) in a suitable loca-
tion in the external additional heat.
•The external supply temperature sensor (AA35-BT25),

a wood/oil/gas/pellet boiler.
You can set shunt valve amplification and shunt valve
waiting time.
Selecting "Prioritised add. heat" uses the heat from the
external additional heat instead of the heat pump. The
shunt valve is regulated as long as heat is available,
otherwise the shunt valve is closed.
See the accessory installation instructions for function
description.
Menu 7.5.3 - Forced control
Here you can force control the various components in
the installation. The most important safety functions

Step controlled
additional heat
GENERAL
This function enables an external additional heater, e.g.
an electric boiler, to aid with heating.
With AXC 30, three potential-free relays can be used for
additional heat control, which then gives max. 3 linear
or 7 binary steps. Inside the control module, a further
three potential-free relays can be used for additional
heat control, which then provides a further 3 linear or 7
binary steps.
The flow through the additional heat is ensured by the
external circulation pump (EB1-GP10).
PIPE CONNECTIONS
The external circulation pump (EM1-GP10) is placed on
the supply line to the climate system after the temper-
ature sensor (AA35-BT25).
If the climate system’s flow exceeds the maximum re-
commended flow for the electric boiler, a bypass must
be installed so that only a partial flow passes through
the electric boiler.
TEMPERATURE SENSOR
•The external supply temperature sensor (AA35-BT25),
connected in the indoor module’s control module,
must be installed on the supply line to the climate
system after the additional heat.
LEK

ternal connections must not be laid close to

Extra climate system
GENERAL
This function is used when SMO S40 is going to control
more than one climate system. It is possible to connect
up to eight different climate systems (heating and/or
cooling systems) that require different supply temperat-
ures, for example where the house has both radiator
systems and underfloor heating systems.
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.
Caution
If a room sensor is used in a room with under-
floor heating, it should only have an indicatory
function, not control of the room temperature.
PIPE CONNECTIONS
GENERAL
When connecting extra climate systems, they must be
connected so that they have a lower working temperat-
ure than the climate system 1.
CIRCULATION PUMP
The extra circulation pump (EP21-GP10) is positioned in
the extra climate system according to the outline dia-
gram.
SHUNT VALVE
The shunt valve (EP21-QN25) is located on the supply
line after the heat pump/indoor module, before the first
radiator in the climate system 1. The return line from
the extra climate system is connected to the shunt valve
and to the return line from the climate system 1, see
image and outline diagram.

• Connect the return line from the climate

• Connect the supply line to the climate system to the
common port AB on the shunt valve (always open).
TEMPERATURE SENSOR
• The supply line sensor (EP21-BT2) is installed on the
pipe between the circulation pump (EP21-GP10) and
shunt valve (EP21-QN25).
