Abstract

A control for a spa and swimming pool pump and heater assembly with diverter valves, includes a selectively actuable pump and spa heater actuator or relay having a first latching circuit, and having a separate first unlatching switch or relay contact, a selectively actuable pump and pool heater actuator or relay having a second latching circuit including the first unlatching switch or relay contact, and having a second unlatching switch or relay contact in the first latching circuit. The control also includes a diverter valve actuator in parallel to one of the pump and spa heater actuator or relay and pump and pool heater actuator or relay.
