LiveWell aerator timer operates the pump in cycling On-Off mode. The period duration can be set from 1 sec to 16 hours. The pump can be configured to run from 0 to 100 % duty cycle. For example, timer can be set to operate at 80% duty for the first ten seconds and then switch to a low 25% duty for the next five minutes. Two optional wires can be configured to override the duty from 0 to 100%, allowing the user to override the pump cycle at any point.
