3.1.4. Connecting external input
Demand control is available by external input.
It is possible to set the outdoor unit’s power consumption by setting the switch of the interface controller.
• REMOTE SWITCH Type A (4bit - 8 setting) / Type B (1bit -1 setting)
Demand control is available by connecting remote switches with terminal No.10 - 14.
Make sure to use the non-voltage switch (for the remote switch)
Remote switch cable length : Maximum 10m
Remote switch : Minimum applicable load DC12V, 1mA

Caution:
The external input signals are separated by basic insulation from power supply for the unit.
The external input signals should be separated by supplementary insulation from where user may touch in case that it is installed where
user may touch.
Connect the terminals by using the ring terminals and also insulate the cables of adjoining terminals when wiring to terminal block.
