1. The dotted line represents a wire procured locally, and the dashed line represents an option sold separately.
2. represents a terminal block, represents a connection terminal,
printed circuit board and represents a short circuit connector.
3. represents a protective ground.
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 (DC12V, 1mA). In addition, ON/OFF operation is possible when using a voltage of
DC12V or 24V.
6. Orange wire (High) is connected as factory default. To switch to "Extra High", connect black wire's connector
instead of orange.
7. The unit cannot run when the temperature of the outdoor air is below -15°C.
