-14- Operation Mode

(1) Indoor unit operation mode

The operation mode can be selected from the following 5 modes using the remote controller.

(2) Outdoor unit operation mode

When the outdoor unit is performing a cooling operation, the operation mode of the connected indoor units that are not in the
cooling mode (Stopped, Fan, Thermo-OFF) cannot be changed to heating from the remote controller. If this attempt is mode,
"Heating" will flash on the remote controller. The opposite is true when the outdoor unit is performing a heating operation. (The
first selection has the priority.)
