The electric pre-heater is controlled via the ventilation unit, which increases the air temperature before it reaches the heat exchanger.
Its purpose is to protect the heat exchanger from freezing and to ensure equal pressure of supply and extract air. This prevents damage to the unit’s components and improves the heat recovery system.
