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 55 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, but it de-
pends on the heat pump that 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.
