Balanced ventilation function
The controller optionally has a balanced ventilation function; it works through controlling the constant air flow in the
ducts. The function allows for increasing the efficiency of heat recovery, making the system proof to changes of system
resistance e.g., due to air filter soiling, changes of heat exchanger resistance due to dampening or soiling or starting the
air flow through the ground-air heat exchanger. Connection of additional elements is described in section 5.6.8.
