With the "Manual ventilation” mode enabled,
the speed of the fan at the various points can

TOUCH PAD
.
Rotating the key clockwise on the pad increases the
speed of the fan while anticlockwise decreases the
speed of the fan.
“Manual ventilation” mode at 100% is the standard op-
erating mode, corresponding to the nominal air flow
rates set by the installer upon initial configuration.
The advanced centralised control systems are
equipped with an RH% humidity sensor or else an
external CO

sensor.
When”
Automatic Mode
” is enabled, fan speed is
controlled by an automatic control cycle relative to
internal instantaneous humidity and CO2 variations.
