    Even the house ventilation affects the energy consumption. It is therefore important to perform a ventilation adjustment shortly after installing the heat pump. At ventilation adjustment, a ventilation technician sets the house ventilation device and the fan in F370 according to the projected values of the house. Also remember: During the adjustment period (winter time) all thermostat valves should be fully open.
