Preheating The Outdoor Air - Nibe GV-HR 130 Series Installer Manual

Preheating the
outdoor air
If the extract air temperature is too low, the supply air
fan slows down to prevent the condensation water in
the heat exchanger from freezing.
To prevent this from happening too often in areas with
colder climates, an electrical air heater, EAH (EB17),
should be installed in the outdoor air duct as illustrated.
EAH heats the incoming outdoor air so that the extract
air temperature does not fall to the stated level.
See the Installer Manual for EAH for more information.
