OPERATING LOGIC OF THE AUTOMATIC SHUTTERS
VENTILATOR OPERATION MODES
The ventilator has four ventilation modes:
• Natural Air
Supply. The automatic shutters are opened, the fan is idle.
• 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 CN7 jumper position.
• Regeneration. The ventilator operates in reversible mode with heat and humidity recovery.
Ventilator is off — the automatic shutters are closed Ventilator is on — the automatic shutters are opened
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.
