VENTILATOR OPERATION MODES
Ventilator operation modes:
Natural air supply — the automatic shutters are opened, the fan does not run.
Air Supply — the ventilator supplies fresh air to the premise.
Ventilation — the ventilator operates in permanent supply or extract mode at set speed depending on the CN7 jumper position.
Regeneration — the ventilator operates in reversible mode with heat and humidity recovery.
In Regeneration mode the ventilator operates in two cycles, 70 seconds each.
Cycle I.
Warm stale air is extracted from the room. As it flows through the regenerator, it heats and moisturizes the regenerator, transferring up to 90 % heat
energy. In 70 seconds as the ceramic regenerator gets warmed the ventilator is switched to supply mode.
Cycle II.
Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and is heated up to the room temperature. In
70 seconds after the regenerator gets cooled down, the ventilator is switched to air extract mode and the cycle is renewed.
