2.1.9 Emergency Operation
If the compressor cannot operate, this control inhibits any applicable compressor or outdoor unit
from operating to perform emergency operation only with the operative compressor or outdoor
unit.
[Automatic backup operation]
With multi-outdoor-unit system, if a certain outdoor unit system malfunctions (i.e., the system
stops and indoor unit remote controller displays the malfunction), by resetting the indoor unit
remote controller, the applicable outdoor unit is inhibited from operating for 8 hours, thus
making it possible to perform emergency operation automatically.
However, in the event any of the following malfunctions occurs, automatic backup operation can
be performed.
