The indoor assembly unit is equipped with automatic shutters. During the ventilator standby the automatic shutters open and let free
air flow through the ventilator. The automatic shutters close 2 minutes after shutdown of the ventilator.
OPERATING LOGIC OF THE AUTOMATIC SHUTTERS
VENTILATOR OPERATION MODES
The ventilator has two ventilation modes:
Ventilation. The ventilator operates either in extract or supply mode at set speed.

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 97% 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.
