Whirlpool bath controller with intelligent load control to reduce power requirements

A control system for a whirlpool bath installation, wherein the bath installation includes a tub, and the high voltage load devices include at least one of a whirlpool pump for pumping water through one or more bath jets, a heater for heating the water, a blower for blowing air through the bath jets or another jet or jets or an air channel, and a micro-bubble pump for forcing water with entrained air through one or more jets, the control system comprising:

• a single input source wiring for connecting to an input source of high voltage AC electrical power having a predetermined nominal maximum current rating;
• a plurality of high voltage output connector sockets electrically connected to the single input source wiring through a corresponding plurality of switches, the high voltage output connector sockets configured for power connections to a respective plurality of high voltage load devices, whose cumulative nominal current draw ratings exceed said current rating of the input source;
• the high voltage load devices including a respective power cord and a power connector adapted to connect to high voltage service connector sockets including the high voltage connector sockets of the control system;
• an electronic controller configured to control states of the switches in response to user input commands received through a system input system, the electronic controller implementing an algorithm or a set of rules preventing a system utilization of the high voltage loads from exceeding a total current draw exceeding said nominal maximum current rating to an extent to cause a circuit breaker or fuse protecting the input source from tripping;
• wherein the high voltage load devices include each of the whirlpool pump, the heater, the blower and the micro-bubble pump, and the electronic controller is configured to prevent the whirlpool pump, the heater and the blower from operating while the micro-bubble pump is operating.
