Backup and Emergency Operation

1. Backup and Emergency Operation
1.1 Backup and Emergency Operation
The PLUS Series is equipped with a function whereby, if one outdoor unit becomes unable to
operate, the system continues to operate without the faulty unit. You should note that this is
accomplished by other methods for other VRV Series.
1.1.1 Backup Operation:
Lets you operate by remote controller when a constant speed type outdoor unit malfunctions.
If a constant speed type outdoor unit malfunctions, if you restart operation by remote controller after the
unit stops due to malfunction, you can continue to operate the system minus the faulty constant speed type
outdoor unit. Operation however cannot be continued for some error types. (See the table below.)
The system can run by backup operation for up to 3 hours of total indoor unit operating time. When 3 hours
is exceeded and the malfunction still remains, the system once again stops due to malfunction. If the
malfunction returns to normal, the system continues to operate as is.
Backup Operation
Control Flow
After the system briefly stops due malfunction in order to call attention to the problem, backup operation is
started by remote controller.
For the reason described above, after about 3 hours of backup operation, the system again carries out
malfunction detection, and the system once again stops due to malfunction if an error is detected.
