The hot air is transferred from the rooms to the heat
pump (EB100) via the building's ventilation system.
The outdoor air is moved via an outdoor air duct via the
outdoor air damper (QN38), adjustment damper (RN1)
to the heat pump (EB100).
Where no adjustment damper (RN1) is used, the opening
angle set for the damper motor can be used to adjust
the air flows. The damper motor's opening angle is ad-
justed using the stop screw, see image.
NOTE
The outdoor air temperature has a very low
temperature. To avoid damaging F730 and/or
the house, it is therefore important that the
damper section, motor shelf and outdoor air
duct are insulated with diffusion-proof material.
The outdoor air duct must be insulated over its
entire length.
TIP
Install the dampers etc. in such a way that they
are easily accessible for any service.
