UNIT FAULT CODE AND LAST UNIT FAULT CODE (XWIUNITGNLFLTCODE)
AV1022 and AV1024 are enumerated values indicating a general fault condition for the unit. The last fault (AV1022)
indicates the most recent previous fault condition for the unit. The value for these objects is decoded as follows:
• 0 – Normal
• 1 – Coil freeze warning active
• 2 – Fire trip mode active
• 3 – Smoke purge mode active
• 4 – Supply fan not running
• 5 – Exhaust fan not running
• 6 – Purge fan not running
• 7 – Exhaust fan VFD fault active
• 8 – Supply fan VFD fault active
• 9 – Purge fan VFD fault active
• 10 – System startup active Normal for 5 minutes after power on.
• 11 – Supply fan deadheaded. Supply fan requested on with both outside air and recirc air dampers less than
25% open.
• 12 – Aux heating system failure
• 13 – Aux cooling system failure
• 14 – Compressor Module 1 fault active
• 15 – Compressor Module 2 fault active
• 16 – Compressor Module 3 fault active
