Air exchange
Low humidity in the dwelling can be prevented by reducing ventilation at low outdoor temperatures.
This function can be used in countries with regular sub-zero temperatures and at high altitudes where
the outdoor air is very dry.
This function can also be used at cold outdoor temperatures if no after-heating element has been
installed, and the supply air feels too cold.
