Exclude rogue zones from this reset sequence. Rogue zones are zones that frequently or constantly make pressure or temperature requests. Possible causes of rogue zones include an undersized VAV box, a cooling thermostat setpoint that is too low, or duct installation problems.
For each rouge zone, increase the pressure or temperature request setpoint by 1.
The discharge air static pressure sensor should be mounted at least two-thirds of the way down the longest duct run.
The following points are already included in the AHU Reset trend study object:
- PRESSREQ-O
- TEMPREQ-O
- SUMWINT-S
Once the following field controller points are added to the database, add them to the AHU Reset trend study also:
- DAP-SP
- DAT-SP
- DA-T
- DA-P
- SF-S
- SF-O
