The ventilator has four ventilation modes:
•
Natural air supply - the automatic shutters are opened, the fan does not run
•
Supply - the ventilator supplies fresh air to the premise no matter of CN7 jumper position.
•
Ventilation — the ventilator operates in permanent supply or extract mode at set speed depending on CN7 jumper position.
•
Regeneration - the ventilator operates in reversible mode with heat and humidity regeneration.
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 and absorbs accumulated moisture and heat up to the room
temperature. In 70 seconds as the ceramic regenerator gets cooled down, the ventilator is switched into extract mode and the cycle is
renewed.
