The element (charging) circuits can be turned OFF by switching all the 60-amp breakers located on the front of the electrical panel to the DOWN position. To turn the element circuits ON, switch all the 60-amp breakers to the UP position. The 15-amp breaker MUST remain ON to operate controls in the system; in conjunction with a heat pump or air conditioner; to control other loads; or using the optional Steffes time clock module.
