UNIT OPERATION MODES
Heat recovery Summer Cooling mode (only for the units with a bypass)
Warm extract air from the room flows into the unit and is cleaned in
the extract filter. Then the air is moved through the heat exchanger
and is exhausted outside with the exhaust fan. Cold fresh air from
outside flows into the unit, where it is cleaned in the intake filter.
Then the air flows through the heat exchanger and is moved to the
room with the supply fan. Supply air is heated in the heat exchanger
by transferring the heat energy of warm and humid extract air to
the cold fresh air. The air flows are fully separated while flowing
through the heat exchanger. Heat recovery minimizes heat losses,
which reduces the cost of space heating in the cold season.

EXHAUST AIR
The bypass damper is opened, the extract air that is removed
from the premises bypasses the heat exchanger. The intake air
temperature remains constant after passing the heat exchanger.

Heat Exchanger Freeze Protection
The unit has two automatic heat exchanger freeze protection modes depending on the unit model.
In case of a freezing danger*, the supply fan is turned off.
To activate the Freeze Protection mode, refer to the user’s manual
for the control panel, the “Engineering menu”, “Additional options”
and “Supply fan shutdown” sections.

*Freezing danger appears when the exhaust air temperature downstream of the heat exchanger falls below +5 °C and the intake air
temperature upstream of the heat exchanger is lower than -3 °C . As the temperature rises the unit returns to the previous mode.
