Emergency operation for compressor malfunction
▪ Purpose
Perform emergency operation until servicing if there is compressor failure when using more than one compressor.
▪ Concept
Faulty compressors are disabled and turned off.
▪ Control specifications in detail
Disabled compressors are excluded from capacity distribution, heat treatment of winding wire, protective control, and
self-diagnosed error detection.
▪ Notes
- The performance may degrade if this option is changed.
- Make sure to return the option to the default value after servicing the compressor.
- Error E560 will be triggered if all the compressors on outdoor units are disabled.
(The SVC V/V must be closed for outdoor units if modules are installed and all the compressors on a single
outdoor unit are disabled.)
