Function

Automatic operation (see downloads)
  • The ventilator is designed both for reversible mode with energy regeneration and supply and extract mode with no regeneration.
  • CYCLE I. Warm stale air is extracted from the room, and then it passes through the ceramic energy accumulator, while flowing through it, heats, moistens the ceramic accumulator, and transfers up to 90% of the contained thermal energy. As the ceramic accumulator gets heated, the ventilator switches to supply mode automatically.
  • CYCLE II. Clean fresh air from outside passes through the ceramic energy accumulator, absorbs moisture and is heated up to the room temperature due to the accumulated heat. As temperature of the accumulator drops down, the fan switches to extract mode and the cycle is renewed. The ventilator changes its operation mode between supply and extract ventilation every 70 seconds.
  • For a continuously balanced ventilation you can use two devices that work alternately
