VLC DDC BV and AV assignments
Each VLC has a number of pre-assigned data points – binary and analog values (BVs and AVs) – which are used to control the Microset II and read status from it. These data points are available from the VLC as BACnet objects. BACnet-compliant devices can access the properties of these objects. For a complete reference of objects and properties available in VLCs, see the Programmer's Guide and Reference for BACtalk Systems (LTBT-TM-PRGRMR).
Note | The following tables reflect only with the Present Value property of the AV and BV objects. These are listed as data points. |
BV assignments
Point | Read only | Description | On action or status | Off action or status |
---|---|---|---|---|
BV64 | NA | Controls occupied/unoccupied or rented/vacant status (see DDC operating modes) | Sets Microset II to occupied or rented operation | Sets Microset II to unoccupied or vacant operation |
BV65 | NA | Sets On/Off mode (see DDC operating modes) | Enables On/Off mode | Disables On/Off mode |
BV66 | ✔ | Override status. Activated in unoccupied or vacant modes when the user initiates override from the Microset II | On when override timer (AV98) is non-zero | Off when the override timer (AV98) is zero |
BV67 | ✔ | Occupied status. Reflect the value of BV64 or BV66. Also reflects user selection of On/Off mode when BC64 is On (see DDC operating modes) | Space is occupied. Current setpoint values (AV99, AV100) are calculated using occupied logic | Space is unoccupied. Current setpoint values (AV99, AV100) are calculated using unoccupied logic |
BV68 | NA | Field service mode and balance mode lockout | Lock out both field service and balance modes | Allow either field service or balance mode |
BV69 | NA | English/metric mode swap (seeDDC operating modes | Swap native units mode between English and metric | Uses units as determined by VLC native units |
BV70 | ✔ | Microset connection status | Microset detected | Microset not detected |
BV71 | ✔ | Native unit mode status from the native mode set in the VLC DDC header | English units | Metric units |
BV721) 2) | NA | Fan low speed | Enable fan low speed status indicator at Microset II | |
BV733) 4) | NA | Fan medium speed | Enable fan medium speed status indicator at Microset II | |
BV745) 6) | NA | Fan high speed | Enable fan high speed status indicator at Microset II | |
BV,,, | NA | And there are more descriptions | more On statuses | and more Off statuses |
AV assignments
Point | Read only | Description | On action or status | Off action or status |
---|---|---|---|---|
AV90 | NA | Controls occupied/unoccupied or rented/vacant status (see DDC operating modes) | Sets Microset II to occupied or rented operation | Sets Microset II to unoccupied or vacant operation |
AV91 | NA | Sets On/Off mode (see DDC operating modes) | Enables On/Off mode | Disables On/Off mode |
AV92 | NA | Controls occupied/unoccupied or rented/vacant status | Sets Microset II to occupied or rented operation | Sets Microset II to unoccupied or vacant operation |
AV93 | NA | Controls occupied/unoccupied or rented/vacant status | Sets Microset II to occupied or rented operation | Sets Microset II to unoccupied or vacant operation |
AV94 | NA | Controls occupied/unoccupied or rented/vacant status | Sets Microset II to occupied or rented operation | Sets Microset II to unoccupied or vacant operation |
AV95 | NA | Controls occupied/unoccupied or rented/vacant status | Sets Microset II to occupied or rented operation | Sets Microset II to unoccupied or vacant operation |
AV96 | NA | Controls occupied/unoccupied or rented/vacant status | Sets Microset II to occupied or rented operation | Sets Microset II to unoccupied or vacant operation |
