VENTILATOR OPERATION MODES
The ventilator has two operation modes:
Ventilation mode.
The ventilator operates in the air supply or air extract mode at set speed.
In this mode in case of installation of two ventilators one ventilator supplies air to the room and the other one extracts used air.
Regeneration mode.
The ventilator operates cyclically in two cycles, 70 seconds each, with heat and humidity recovery.
•
Cycle I.
Warm stale air is extracted from the room. As it flows through the regenerator, it heats and moisturizes the regenerator,
transferring heat and air moisture. 70 seconds after the ceramic regenerator starts to get warmed the ventilator is switched to the air
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, after cooling of the ceramic regenerator, the ventilator is switched to the air extract mode and the
cycle is renewed. In this mode in case of installation of two ventilators they run in opposite directions. One ventilator supplies air to
the room and the other one extracts used air.
