Remote actuator system

Abstract

A control system for selectively turning on and off various electrical devices used in the operation of a spa is disclosed. The control system includes a power supply for generating a 5 volt DC voltage from a 120 volt AC external power source, a timing circuit, a clearing circuit and a plurality of control circuits, one for each device to be controlled. Each control circuit, which is driven by the 5 volt DC voltage, includes a relay which is adapted to be coupled to the electrical device to be controlled, a momentary manually operated switch, a pair of flip-flops, a gate, a transistor, and an incadescent light bulb. In the operation of the circuit the transistor is turned on and off by the flip-flops and the output of the transistor is used to energize or deenergize the relay. Because the circuits operate at low DC voltage, the switches through which these voltages are transmitted can be located at or near the spa without causing potential safety problems. In a specific embodiment disclosed, an air blower pump, a booster pump, a circulating pump and a heater are controlled and the lighted switches are located in a first box adapted to be located at the vicinity of the spa. The first box is connected by wires to a second box containing the other components and is adapted to be located remote from the spa, preferably in the vicinity of the electrical devices being controlled. Integrated circuits and passive parts are used for all components in the control system.
