General
Pipe installation must be carried out in accordance with
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 20 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 48 for a list of the accessories
that can be used with SMO 20.
Installations with SMO 20 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.
