The choice of operating mode is carried out by setting the DIP switch to a certain position. Use the plastic screwdriver from
the delivery set to set the DIP-switch to a required position.
Operation mode 1 (single-speed)
The fan is turned off by default. The fan starts operating at low speed when the switch is turned on or one of the sensors is
activated.
Operation mode 2 (single-speed)
The fan is turned off by default. The fan starts operating at high speed when the switch is turned on or one of the sensors
is activated.
Operation mode 3 (two-speed)
The fan operates at low speed by default. The fan switches to the high speed when the switch is turned on or a sensor is
activated.
Operation mode 4 (two-speed)
The fan is turned off by default. The fan starts operating at low speed when the switch is turned on and switches to high
speed when the humidity sensor is activated.
Operation mode 5 (two-speed)
The fan is turned off by default. The fan starts operating at low speed when the switch is turned on.
If during the operation at low speed the humidity sensor is activated or the switch is turned on, the fan switches to high
speed.
CAUTION!
The operation mode 1 is set by default. The operation mode may be changed during the fan mounting or
operation. Setting the DIP switch to any position other than stated in the table results in the emergency mode communicated
by the red light indication. In such a case disconnect the fan from power supply and set the DIP switch to a correct position.
