Demand Control function is responsible for IAQ (Indoor Air Quality) regulation. Relative humidity (RH) and/or CO
sors are responsible for IAQ monitoring.
Indoor air quality (IAQ) indicator is available if AUTO mode and Demand Control function is activated.
IAQ levels:
• ECONOMIC: Actual IAQ value is below low IAQ set point.
• GOOD: Actual IAQ value is between low and high IAQ limits.
• IMPROVING: Actual IAQ value is above high IAQ set point.
Different airflow settings can be set for IMPROVING and GOOD IAQ levels in Service menu.

Connected heater or pre-heater is active and air heating is in process.
Heat recovery from apartment is active.
Connected cooler is active and air cooling is in process.
Automatic cooling recovery is active when extract air temperature from
apartment is lower than outdoor air temperature and there is a cooling demand
(temperature setpoint is lower than outdoor air temperature).
No cooling recovery with heating demand. If the outdoor air temperature is
higher than then thee indoor air temperature and there is a heating demand,
function Free heating is activated instead.
Function decreases indoor air temperature by using only cool outdoor air during
nighttime to save energy consumption.
Function controls the rotation speed of the heat exchanger to prevent moisture
transfer to supply air due to high relative humidity in the extract air.
Function is only available for units with Rotating type heat exchanger.
Function prevents formation of the ice on the heat exchanger during cold
outdoor temperatures.
Warm air from the living space is used to defrost the heat exchanger using a
damper inside the outdoor air duct. The unit switches from outdoor air to
secondary air while the extract air fan stops and warm secondary air increases
the temperature inside the heat exchanger.
