Fault History
Supply fan vibration crossed warning threshold (5.0 mm/s). Reading: 5.06 mm/s. Rapid onset over ~10 days suggests belt wear or sheave misalignment - inspect drive assembly.
Discharge air temperature 11.4 C below setpoint during extreme cold (OA -13.5 C). HW valve response verified; condition self-recovered as coil load stabilized.
Service History
Triggered by: Analytics: OA damper averaging ~30% open during free-cooling conditions (expected ~70%); no alarm raised
Economizer OA damper actuator recalibrated - feedback signal had drifted ~35% low, so the damper under-delivered outdoor air during economizer operation. Free-cooling stroke verified at commanded 70%.
Triggered by: Scheduled quarterly PM (calendar)
Q2 preventive inspection incl. scheduled MERV-13 filter bank replacement (pre-change DP 88 Pa). Coils cleaned, condensate pan treated, sensors calibrated.
Triggered by: Scheduled quarterly PM (calendar)
Q1 preventive inspection. Belt tension OK. Heat-recovery wheel seals inspected. Filter DP 62 Pa - within spec. Freeze-stat tested OK.
