VENTILATOR OPERATION MODES
The ventilator has two ventilation modes:
Ventilation. The ventilator operates in permanent supply or extract mode at set speed.
In case of two ventilators operating in
this mode one ventilator operates in supply and the other one in extract mode.
Regeneration. The ventilator operates in reversible mode with heat and humidity regeneration 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.
In this operation mode in case each of two installed ventilator operate two cycles in opposite phases.
While one ventilator operates in air supply mode the other one operates in air extraction mode.
