The bypass operations that can be performed by BACnet communication depend on parameter settings. This section explains

the functions that can be used and related parameter settings.

Observing the Bypass Operation

A controller can perform the following actions with BACnet communications at any time regardless of parameter settings:
• Observe bypass and drive status and control terminal status from a controller
• Read and write parameters
• Set and reset faults
• Set multi-function inputs.

Note:

Input settings from the input terminals So and from BACnet communications are both linked by a logical OR operation.
