Switch Setting Explanation
Use this rotary switch to specify the speed stages of the fan.
The fan is switched OFF
1)
The fan is operated with the preset rotational speed (1-3).
AUTO
Auto: the speed stages are automatically specified by the controller. The greater the deviation of
the room temperature from the setpoint, the higher the fan speed.
NOTICE!
The manual specification "0" Fan OFF has a lower priority than a specification in
the Modbus interface or digital input, i.e. if the compact controller is switched off
with the digital input or Modbus, the unit will remain switched off if the rotary switch
is e.g. set to fan speed OFF "1".
