Mounting
SMO 05 cannot be installed directly against a wall be-
cause the connection terminal protrudes from the reverse.
Install SMO 05 either in a spare apparatus box or on the
plastic spacer supplied.
If you want to use the room temperature sensor in SMO
05 the position of the room unit is important. See page
13.
1.
LEK
Open SMO 05 by inserting a screwdriver in one of
the 4 mm wide gaps in the edge. Press the screw-
driver straight in to open the clips. Repeat for the
other three clips.
2.
LEK
Without plastic spacer: Place the rear panel in front
of the apparatus box and screw to the wall.
With plastic spacer: Screw the plastic spacer into the
wall. Then screw the the rear panel into the plastic
spacer with the two screws supplied.
3.
LEK
Connect the room unit, see page 12.
4.
LEK
Angle the front panel approx. 30 ° and secure the
two clips on one side. Then close the unit and secure
the two clips on the other side.

Outside sensor
Install the outside temperature sensor (BT1) in the shade
on a wall facing north or north-west, so it is unaffected
by the morning sun.
Connect the sensor to terminal block X2:23 and X2:24
on the accessory card (AA5). Use a 2 core cable of at least
0.5 mm² cable area.
If a conduit is used it must be sealed to prevent condens-
ation in the sensor capsule.

Room sensor
SMO 05 is delivered with a room sensor supplied (BT50).
The room temperature sensor has up to three functions:
1. Show current room temperature in the heat pump's
display.
2. Option of changing the room temperature in °C.
3. Makes it possible to change/stabilise the room tem-
perature.
Install the sensor in a neutral position where the set
temperature is required. A suitable location is on a free
inner wall in a hall approx. 1.5 m above the floor. It is
important that the sensor is not obstructed from measur-
ing the correct room temperature by being located, for
example, in a recess, between shelves, behind a curtain,
above or close to a heat source, in a draft from an extern-
al door or in direct sunlight. Closed radiator thermostats
can also cause problems.
SMO 05 operates without the sensor, but if one wishes
to read off the accommodation's indoor temperature in
SMO 05’s display the sensor must be installed. Connect
the room temperature sensor to X2:15 and X2:16 on the
accessory card (AA5).
Use a 2 core cable of at least 0.5 mm² cable area.

Changes of temperature in accommodation take
time. For example, short time periods in combin-
ation with underfloor heating will not give a
noticeable difference in room temperature.

Temperature sensor, hot water charging
The temperature sensor, hot water charging (BT6) is
placed in the submerged tube on the water heater.
Connect the sensor to terminal block X2:21 and X2:22
on the accessory card (AA5). Use a 2 core cable of at least
0.5 mm² cable area.
Hot water charging can be activated in menu 5.2.

minal block X2:11 and X2:12 (addition) respectively ter-
minal block X2:13 and X2:14 (compressor) on the access-
ory card (AA5).
The addition and/or the compressor are disconnected by
connecting a potential free switch function to actual ter-
minal block. Use a 2 core cable of at least 0.5 mm² cable
area.
External blocking of addition and compressor can be
combined.
A closed contact results in the electrical output being
disconnected.
