Description/Action
the control system ends the heating cycle. A heating cycle is
activated again when the sensed water temperature drops below
the Operating Set Point minus the Differential setting.
NOTE: Lower Differential settings may cause excessive heating
cycles (short-cycling) which can cause premature failure of heater
components. Set the Differential at the highest setting which
produces an acceptable hot water supply. Set the Operating Set
Point to the lowest setting which produces an acceptable hot
water supply for most efficient use.
