DESIGN AND FUNCTIONING

The unit has the following operating principle: warm stale extract air from the room flows into the unit, where it is filtered by the extract
filters, then air flows through the heat exchanger and is exhausted outside by the extract fan. Cold fresh air from the outside flows into
the unit, where it is cleaned by the supply filters. Then the air flows through the heat exchanger and is directed to the room with the
supply fan. Heat energy of warm extract air is transferred to clean intake fresh air from the outside and warms it up. 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 (for units with an A14 control panel)
or a thermostat (for units with an A2 control panel). The temperature sensor is 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). If necessary, this setting can be changed
within the software. To set the thermostat temperature set point, set the temperature control knob into a respective position.
