*Some electrical utilities give discounts if electricity is used during "Off Peak" times of the day. This circuit
allows use of an "Off Peak" meter, which interrupts power to the lower element during the time of day when
electricity is more expensive. This customer relies on additional hot water storage to meet their needs while
this element is off.
