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 system with 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.
Malfunctions under which automatic backup operation can be performed:
• E3, E4, E5, E7
• F3
• H7, H9
• J2, J3, J5, J6, J7, J9, JA, JC
• L3, L4, L5, L8, L9, LC
• U2, UJ
"Inhibition of operation" is set with each outdoor unit.
