Service and maintenance Bypass function When the current room temperature is above the desired temperature, there is no further need for heat recovery. In this situation, the bypass opens and diverts the outdoor air round the heat exchanger, preventing the latter from being heated by the indoor air. This results in lower internal pressure in the unit, thereby saving energy on fan operation.
