Remarks
AI-(0) AI-0 is the MS/TP Microset II internal sensor analog input object.
AV-(90–107) RESERVED AVs for Alerton legacy Microset behavior.
AV-(0-47) General use AVs.
BV-(0-47) General use BVs. BV-40 supports the priority-array property.
BV-40 is typically used by Alerton DDC applications to receive scheduled occupancy
commands from a global controller. The priority array allows a BACnet user to override
the occupancy command. When in Occupancy mode with an internal schedule enabled,
internal schedule commands are written to BV-40 priority 16, therefore DDC
applications that use BV-40 can easily use either internal or external scheduling.
BV-(99) Disable unoccupied setpoint deadband
