VENTILATOR OPERATION MODES
Ventilation:
the ventilator runs either in air extraction or air supply mode at a set speed.
In this mode some of the ventilators in the network run in air supply mode and the other ones in air extraction mode, depending on
the position of the DIP switch No. 3 (see page 12).
Boost
: the ventilator goes to the maximum speed without changing the operation mode.
Regeneration:
the ventilator runs in two cycles, 70 seconds each, with heat and humidity regeneration.
•
Cycle I.
Warm stale air is extracted from the room and flows through the ceramic regenerator, which gradually absorbs heat and
humidity. In 70 seconds, as the ceramic regenerator gets warmed, the ventilator is switched to air 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, as the ceramic regenerator gets cooled down, the ventilator is switched to air extraction
mode and the cycle is renewed. If two ventilators are installed, they operate with opposite rotation directions in this mode. While
one ventilator supplies air, the other one extracts it.
Air supply:
the ventilator operates in air supply mode irrespective of the position of the DIP switch No. 3 (see page 12).
