- Speed selection button : three buttons allow you to change the fan speed (and its flow). The button with
the darker fan activates the highest speed, and vice versa.
- Ventilation button : the device operates in fan mode only. The air flow direction (supply or extraction) is
determined by the location of the dip two (by default the unit operates in extraction).
- Heat recovery button : it enables the heat recovery. The unit operates for 65 sec in supply and for 65
seconds in extraction. The heat recovery system recovers the energy in sequence from the exhaust flow
into the fresh air supply flow.
- Button party : the device keeps the maximum speed for four hours. After this time, it goes back to the
previously set speed. To disable this function, press any of the three speed buttons.
- Night button: the device will operate at minimum speed for eight hours, after which it will return to the
previously set speed. To disable the function, press any of the three speed buttons
Make sure the remote control is properly powered before the use (charged batteries, free and clean contacts).
The remote control should not be affected by interferences or external EMC noise. The operating range depends
on the external conditions, the level of charge of the batteries and the distance from the unit.
