Heat recovery
Warm stale extract air from the room flows into the unit, where it is
filtered by the exhaust filter, then air flows through the heat exchanger
and is exhausted outside by the exhaust fan. Cold fresh air from the
outside flows into the unit, where it is cleaned by the supply filter. Then
the air flows through the heat exchanger and is directed 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.

Freeze protection
The heat exchanger freeze protection function of the unit is implemented
with a temperature sensor installed in the exhaust air duct downstream
of the heat exchanger. In case of a freezing danger the supply fan is
turned off and the heat exchanger is warmed up with warm extract air
flow. The recommended sensor or thermostat operating temperature is
+3 °C (exhaust air temperature behind the heat exchanger). If necessary,
this set point can be edited using the software. After temperature
increase the unit returns to the previous operation mode.

Summer Cooling mode
The bypass dampers are open and both air flows do not come in
contact with the heat exchanger.
