3.18 Backup Operation
[Purpose]
The following backup operation is activated when the constant-speed compressor protection device
operates.
< For 2-compressor system >
When the STD compressor OC operates, the operation continues using only the inverter compressor
based on all remote control reset. (for 3 hours only)
< For 3-compressor system >
When the STD compressor OC operates, the operation continues using compressor except last started
STD compressor based on remote control reset. (for 3 hours only)
When OC operates again immediately after a backup operation (within 5 minutes after STD compressor
startup), STD1 and STD2 are switched and operation is retried.
If OC activates again, only the inverter compressor is used for the operation.
(In any case, the backup operation ends after 3 hours.)
The compressor in which OC is activated is prohibited to operate until power reset is conducted for a
restart.
