"Dip-switch" functions (microswitch)
Dip-switch 1
In open contact position, it permits to activate the frost protection
function ( ).
Dip-switch 2
In open contact position, it permits the fan operation at the selected
Dip-switch 3
In open contact position, it restricts the range of the temperature
selection knob according to the following limits:
Cooling: minimum selectable temperature: 23°C.
Heating: maximum selectable temperature: 21°C.
Dip-switch 4
In open contact position, it permits to activate the fan periodically
Dip-switch 5
In open contact position, it permits to activate the Booster Heating
function (additional heating).
Dip-switchs 6, 7 and 8
The position of these dip-switches regulates the control current of
the motor. A higher voltage corresponds to a higher speed of the
fan. The selection is made according to the following table:
