44. . Heat recovery operation principleHeat recovery operation principle
The heat recovery system ensures continuous replacement of used air with fresh, clean air. Heat recovery takes place in the
exchanger, where the supplied air receives part of heat and humidity from extracted air (mainly from kitchen, bathroom etc.).
Therefore fresh air which continuously flows into the interior (living room, children’s rooms, guest bedroom, office etc.) is
thermally optimized. The fresh air is also filtered before it is supplied. To prevent dust buildup on fan blades the extracted air is
filtered as well. The two air streams are separated so that fresh and used air do not mix.
An automatic bypass enabling after-cooling during summer months (in the night mode) is integrated in the heat recovery unit. As
heat recovery is not desirable during summer the bypass channel directs extracted air outside of the exchanger and thus
prevents cooler night air from being heated up by the warm extracted air.

operation prevents fans from stopping while the unit is in the Auto mode running according to data from the CO2 sensors. During
winter operation, the fans do not stop. Their speed decreases to Level 1 instead. When the unit is switched into the winter
operation while the circulation mode is on, the circulation mode is deactivated.
77..1212. . DryingDrying
The heat recovery unit is technically as well as structurally ready for operation at temperatures below the freezing point without
the need of preheating down to -19 °C (-2 °F). When the outside temperatures remain below freezing point, the unit may
occasionally switch into drying mode. This mode removes excess moisture from the unit. It is fully automatic, the unit activates
drying mode as necessary according to operation logic evaluation. The time span between two drying cycles is not fixed.
Drying lasts three hours.
The flaps of the heat exchanger are further turned over in intervals determined by the dew point temperature.
Heating (internal or CoolBreeze) is turned on the maximum.
The bypass flap is shut and the circulation flap is open.
The speed of both fans is set to 20%. Balancing of the pressure is not active, but the Overpressure mode and Anti-radon
Protection mode stay on.
Too low Outdoor Temperature and Settings symbols are displayed on the wall-mounted control panel.
Thanks to this function no other frost protection in the form of electric preheating is necessary. During this mode, the user
comfort is not reduced; the air that is supplied to the indoor space is warmer than the air that is exhausted. If the Boost function
is activated during drying, the forced exhaust time is limited to 2 minutes. The drying mode cannot be deactivated by the user
and in case of a power outage, the drying mode is resumed after the unit is on.
7.12.1. Drying at extremely low outdoor temperature
A mode started automatically when the outdoor temperature drops and remains below -20 °C (-4 °F) for 16 minutes. This mode is
deactivated when the temperature rises to -18 °C (0 °F). Too low Outdoor Temperature and Warning symbols are displayed on
the wall-mounted control panel. After the drying is finished, the ventilation and filter check are blocked, Boost is limited to 2
minutes, the unit continues to run in the Circulation mode.
7.12.2. Drying during prolonged low outdoor temperature
Drying mode is activated when the temperature of exhausted air drops below -5 °C and does not rise above -1 °C during the
following 72 hours. In case of a restart or a power outage the elapsed drying time is saved and when the unit is back on, the
drying mode is resumed for the remaining period of time.
7.12.3. Drying after the fans have stopped
When the fans stop running for 35 seconds or longer, while the temperature of the exhausted air is below 0 °C, the drying is
activated.
