AAON Main DX Barrel Chiller Controller BACnet objects

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.

Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

No points match these filters. Clear filters

Integration notes

• The guide gives no read/write column; AI, BI and MI are shown read-only and AV writable from the object types and the limit ranges.
• Refrigerant points are grouped per barrel and circuit (B1:C1 ... B2:C3), so instance numbers have gaps.
• Points for the chiller pumping module, waterside economizer, evaporative condenser and vestibules report only when fitted.
• Binary input descriptions are the guide's value type column (Status, Alarm, Fault, Warning, Lockout).
• Source: BACnet section, guide pages 81-93.
