With both "HOA" switches in "Auto" and the pump selector switch in "ALT": On water rise, the "off" float will
close and when the level closes the "lead" float, pump 1 will start and pump down to the "off" float. The
panel will alternate so on the next cycle pump 2 will activate. If the level reaches the "lag" float, both
pumps and the alarm will activate and pump down to the "off" float. Alarm turns off at the "off" level. For a
pump up application the floats are reversed (see float configurations Fig. #A on page 4).
