A: SPEED SELECTION KEY: 5 position selector (Night / Quiet / Performance / High performance / Boost).
LED 1- LED 5: speed / air flow from min to max. Press the button sequentially to select the desired speed
setting. 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 sequentially to cycle through the different operating 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 as a heat recovery unit, with cyclic inversion of the direction of
rotation).
• INTAKE the system operates as a fan, supplying are to the room .
• 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, (or
Mesh network, WiFi models only), 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: natural ventilation can be selected automatically via the external IR remote control (see fig. 23).
Note 2: The RS485 bus (or the WiFi module, WiFi models only), allows to balance the air flow rates of
intake and extracted air, provided that the total number of installed units is equal to an even
number. For exaple, 4 units can be connected on the RS485 bus setting two units as "even" and
two units as "odd". In the case of an installation of an odd number of units, the air flows balancing
will not occur.
Note 3: To see how to set the device as an even or an odd unit, refer to the section "parameter
programming sequences".
Note 4: The backlighting of the keys on the device remains active for one minute from the last press of
any key.
Note 5:The backlighting of the keys on the remote control remains active for 15 seconds from the last
press of any key.
C: FUNCTION KEY to activate or deactivate 3 different AUTO functions available and activate or deactivate the
stand-by mode.
To activate or deactivate the stand-by mode:
If the device is switched on and the FUNCTION key is pressed (stand-by / on-off function), the fan stops and the
LEDs of the SPEED column turn off. If the appliance is off and you press the FUNCTION button, the appliance
starts at the speed and mode previously set.
