• bC n — Logs the value recorded by Pb3 on return from a blackout (bOt); n=1...8 blackouts, no effect on regulation
• bt n — Stores the out-of-range dwell time of the Pb3 value during a blackout (bOt); value is 0 if Pb3 stayed within range, non-zero if it went out of range (n=1...8)
• COH — Over Heating alarm — Pb3 value has exceeded the SA3 (Setpoint) parameter; regulation (compressor) locked
• E3 — Probe 3 (Pb3) faulty — measured value outside operating range, or probe faulty/short-circuited/open
• HC n — Logs the Max/Min value recorded by Pb3 when it exceeds range SLH...SHH (HACCP log, n=1...8, no effect on regulation)
• nPA — General pressure switch alarm — pressure alarm activated by general pressure switch, number N of activations below limit PEn; compressor and fans locked, automatic reset
• PAL — General pressure switch alarm (critical) — number N of pressure switch activations equals limit PEn; device locked, manual reset via rAP function required
• tC n — Stores the dwell time of the Pb3 value outside range SLH...SHH (HACCP log, n=1...8, no effect on regulation)
