TECHNICAL DATA
the unit against icing up, even at
very low outside temperatures.
WATER HEATING SURFACE (optional)
Once the temperature and CO2 level
of the room become too high, the sense
of well-being decreases and productivity
drops. There is also an increased risk
of absence through illness.

If the unit is to be installed in a room where air humidity level is high, we
recommend connecting the unit’s integrated condensate drain or adding
a condensate pump (se page 22).
It is also possible to connect ductwork to either supply or extract or both.
