1. The dotted line represents a wire procured locally, and the dashed line represents an option sold separately.
2. represents a terminal block,
printed circuit board and
3. represents a protective earth.
4. represents a printed circuit board.
5. Using a no voltage a-contact input of the external input (sold separately), the following operations are available:
Between 1 and 2: Selecting the remote controller operation (Invalid / Valid)
Between 1 and 3: Adjusting the fan speed (Low / High)
Between 1 and 5: Operation (ON/OFF)
Use a microcurrent contact (DC12 V, 1 mA). In addition, ON/OFF operation is possible when using a voltage of
DC12 V or 24 V.
6. Orange wire (High) is connected as factory default. To switch to "Extra High", connect black wire's connector
instead of orange.
