• Notes on using external functions (Model 500 only)

(*1)

For instructions on how to install the short circuit plate, refer to “Notes on using

external input function” shown below.

When using the external input function on the indoor unit that is connected to a two­refrigerant circuit, connect the short-circuit plate that is supplied with the unit to the
appropriate terminals on the external input-output board.
Without the short-circuit plate, the unit will not function properly.
Don’t connect the short-circuit plate in case of a one-refrigerant circuit.
