Outdoor
Compensation
A purpose of this function is to protect the unit from freezing by creating an unbalanced airflow
at extreme winter temperatures or to limit supply of cold/hot outdoor air at extreme winter/
summer conditions with balanced ventilation.
Function operates by lowering the speed of supply air fan (SAF) or both supply and extract air
fans (SAF/EAFC) by value set in Stop Compensation Value setting (adjustable from 0% to
50%) if the outdoor air temperature (OAT) drops below adjustable value set in Start
Compensation Temperature setting (during winter from 0 °C to -30 °C / during summer
from 15 °C to 30 °C). This compensation reaches the maximum as soon as the outdoor air
temperature reaches the adjustable value set in Stop Compensation Temperature setting
(during winter from 0 °C to -30 °C / during summer from 15 °C to 30 °C)
