convenience of oil equalization.
• For RXYQ14MA and 16MA, only the STD1 compressor cannot be put into operation
prohibition mode for the convenience of oil equalization.
• For the system with a single outdoor unit (RXYQ8MA to 16MA), automatic backup operation is
not functional.
5.2.3 In The Case of Multi-Outdoor-Unit System (RXYQ18MA to 48MA)
[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
[Emergency operation with settings in service mode]
∗
“Inhibition of operation” is set with each outdoor unit.
Make the following settings with the master unit. (Setting with the slave unit becomes disabled.)
∗
Discriminate the operating status of the master unit / slave units through the following LED
