1.11.1 Failure in the System and its Backup Operation
Note :
1. ( ) indicates that backup operation of all or part of functions within the scope of influence by equipment failure is
possible.
“Corresponding group” is a group of air-conditioner controlled by local remote controller, where the failure is occurred.
“Corresponding system” is a group of air-conditioner controlled by Interface for use in BACnet

, where the failure is
occurred.
2. The chance that all local remote controllers and Interface for use in BACnet
®
becomes out of order is almost
negligible, so that the case is not included in the above.
