3.1 - Functions
TheHEEcontrolincludesatemperatureselector(rangefrom
10°C to 30°C) that maintains the room temperature at the
selectedvalue.

●In automatic mode, the fan speeds are controlled by a
microprocessor housed in the control unit, according to
the temperature selected. (see table of 3 speeds possible
