The control will cycle loads on/off based on the setting of the control knobs as long as input power is supplied. The control will start with the on time cycle after initial power is applied

to the control. The unit is simple to set consisting of only two dials: one CYCLE TIME dial to set time durations and one % ON dial to set the percentage of ON time for the selected

duration.

Total cycle duration can be set from 15 seconds minimum to 24 hours maximum, The % ON setting for each cycle duration is independently adjustable from 0% (continuous OFF) to

100% (continuous ON) in 32 increments
