This read-write integer, in hundredths of an amp (0-2000, i.e. up to 20.00A) with 0 meaning the limit is disabled, sets the early warning threshold for unexpectedly low current draw on the Y-Z phase-pair of circuit 1. This gives an administrator a heads-up that load on circuit 1's Y-Z leg is drifting down, perhaps because a device is idling or partially failing, before it falls all the way to the harder yz1MinCurr floor. For example, setting yz1WarnLoCurr to 200 (2.00A) would warn when Y-Z's draw dips under 2 amps, ahead of any 1-amp yz1MinCurr alarm.
