VENTO Eco / VENTO Eco2
UNIT OPERATION MODES
The unit has two ventilation modes:
Ventilation.
The unit operates in permanent supply or extract mode at set speed. In case of two units operating in this mode one unit
operates in supply and the other one in extract mode.
Regeneration.
The unit operates in reversible mode with heat and humidity regeneration in two cycles, 70 seconds each.
Cycle I.
As warm stale extract air flows through the ceramic regenerator, it heats up and moisturizes the regenerator and transfers up to 97 %
of heat energy.
In 70 seconds as the ceramic regenerator gets warmed the unit is switched to 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 unit is switched to air extract mode and the cycle is renewed.
In this operation mode, in case if two units are installed each of them operates two cycles in opposite phases.
While one unit operates in air supply mode the other one operates in air extract mode.
