Fault History

F-HP-TRIPTRIP
Jun 18, 2026, 2:30 p.m. · cleared Jun 18, 2026, 4:00 p.m.

High discharge-pressure safety trip at peak heat-wave load (OA 34.7 C). Fouled condenser could not reject heat at full load. Unit locked out pending inspection.

F-COP-LOWWARNING
Jun 10, 2026, 1:00 p.m. · cleared Jun 19, 2026, 8:00 a.m.

Chiller efficiency degraded: COP trending ~4.1 against ~5.2 expected at this condition. Condenser approach temperature elevated - coil fouling suspected. Schedule condenser cleaning.
