HOT_LOOP_TEMP_MON
Multi-point hot-loop temperature aggregate with cold-point identification, per-channel rejection and a time-below-minimum record.
When to use it
Use HOT_LOOP_TEMP_MON when a self-sanitising water loop is instrumented at several points — supply, mid-loop, sub-loop returns, main return — and the sanitising claim rests on the COLDEST of them staying above the minimum rather than on the supply temperature.
