Ventilation at times of low outdoor air temperatureIt is possible to prevent low humidity in the home by reducing ventilation in case of low outdoortemperatures. This function is particularly useful in countries with heavy frosts and at high altitudeswhere the outdoor air is very dry.The function can also be used if no after-heating element has been fitted, and the supply air feels toocold in case of low outdoor air temperature. Lower ventilation levels will increase temperatureefficiency and thus raise the supply air temperature slightly.The Compact P heat pump is able to heat supply air up to 34 °C in periods where no domestic hot wateris produced.VentilationLow outdoor temperature settings↳ Low fan speed at low outdoor temp.
