EXTRA CYCLE OPERATION AND MODULATING REGENERATIVE RECOVERY
The master in auto mode has the purpose of controlling
the injection and extraction time to optimize the
regenerative recovery cycle of the system.
When the "Auto" mode is first activated, after 10 minutes
and then every 12 hours, the "Master" ventilation unit
performs the "Extra-cycle" procedure to detect the
difference in temperature between the environment and
the outside in order to to determine the most suitable
duration of the “Automatic cycle”.
The “Extra-cycle” procedure lasts 5 minutes, during which
communication with the radio control is inhibited; in this
phase, any commands given with the remote control will
have as a result three flashes of the LEDs.
The duration of the recovery cycle is determined in Auto
by the outcome of the “Extra-cycle” procedure and can
vary between 30 and 200 seconds, which will be divided
equally between the extraction and injection phases.

DEHUMIDIFICATION
A humidity sensor allows each individual ventilation unit to
detect the ambient humidity, and if necessary, to
independently activate high-speed air extraction cycles to
reduce humidity and improve environmental comfort.
Depending on the environmental humidity conditions, the
procedure can last between 2 ÷ 12 minutes (during which
communication with the radio control is inhibited) and can
be repeated every hour. The dehumidification cycle is
suspended in “Night mode”.
Note:
This feature is normally disabled; to enable it, see
the paragraph “Parameter setting”.

BRIGHTNESS SENSOR
A brightness sensor allows each single
ventilation unit to independently adopt the
minimum speed (extra-low) during the night. If
necessary, the brightness sensors can be
excluded; in this case the night speed can only
be activated manually using the appropriate
button on the remote control.
Note:
This feature is normally disabled; to
enable it, see the paragraph “Parameter
setting”.
