of indoor units (Note 1)
(Note 1) If an attempt is made to put into operation a group of indoor units whose total capacity exceeds the maximum allowable capacity,
some of the indoor units will go into the same condition as Thermo-OFF.
(3) Ending the emergency operation
When communication is restored, the emergency mode is cancelled, and the units go into the normal operation mode.

-14- Operation Mode

(1) Indoor unit operation mode
The operation mode can be selected from the following 5 modes using the remote controller.
1 Cooling mode
2 Heating mode
3 Dry mode
4 Fan mode
5 Stopping mode
(2) Outdoor unit operation mode
1 Cooling mode
2 Heating mode
3 Stopping 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.)
