A: SPEED KEY: 5 position selector (Night / Quiet / Performance / High performance / Boost).
LED 1- LED 5: speed / air flow from min to max. Press the button cyclically to select the desired value. The
white LEDs from 1 to 5 will light up to indicate the speed from 1 to 5.
B: MODE KEY: three position selector. Press repeatedly to cycle through the different modes: recovery, intake,
extraction, natural ventilation (intake and extraction LEDs switch on simultaneously).
The respective LEDs will light up steadily:
• RECOVERY heat recovery (the system works like an heat recovery unit, with cyclic inversion of the direction
of rotation).
• INTAKE the system operates as a fan, with room air intake.
• EXTRACTION the system works as a fan, with air extraction from the room.
• NATURAL VENTILATION If the device is connected to one or more units via RS485 communication bus, you
can set the NATURAL VENTILATION mode: if set as an even unit the device will operate in extraction mode,
if set as an odd unit the device will operate in intake mode, creating an air current in the environment.
Note 1: In the HCS versions, natural ventilation can be selected automatically via the external IR remote
