Description: This is a plug-and-play solution that allows connection of the VLT HVAC Drive to building management systems using the BACnet/IP protocol. It complies with the B-AAC (BACnet Advanced Application Controller) profile. The VLT BACnet/IP MCA 125 includes subscribe COV (change of value), which reduces polling for data from the BMS; alarm and event management that can automatically send alarms without polling; and trend object functionality that allows the user to trend inside the drive and not tie up the BMS. The module also incorporates battery-free clock synchronization with the BMS, which eliminates periodic battery maintenance and disposal.
