Abstract
An improved spa control system is disclosed. The improvements may be made individually or in conjunction with any combination of all of the other improvements of the present invention. The invention describes a spa control system which calculates the rate of heating of the heater of the water in the spa to control the operation of the heating element. The system uses a interconnection panel to link a control panel to the power supply and to the operative components of the system. The unique connection of the control panel to the interconnection panel permits the control panel to be located adjacent to the spa.
Claims13
A spa control system comprising a control panel, output components, and a heating element which heats the water in the spa, and further comprising:
- a solid state sensor for detecting the temperature of water in the spa;
- a solid state sensor for detecting the temperature of the heating element;
- and
- a microcomputer for processing the signals from said sensors to calculate the temperature of the water and the heating element so that the heating element controls the temperature of the water within a prescribed range.
A spa control system for detecting the malfunction of components within the system, comprising:
- a display;
- a pump;
- a heating element;
- a system interconnection panel which is connected to said pump and said heater;
- and
- a microcomputer for detecting the malfunction of said pump or said heating element and for generating a signal which illuminates said display to show the malfunction of the component.
A spa control system for controlling the temperature of water in the spa, comprising:
- a heating element for heating the water;
- a solid state sensor for detecting the temperature of the water;
- a solid state sensor for detecting the temperature of said heating element;
- a microcomputer for processing signals generated by said sensors to compute the temperature of the water and of said heating element, wherein said microcomputer activates and deactivates said heating element to control the temperature of said water within a selected range.
A spa control system for controlling the temperature of water in a spa, comprising:
- a system interconnection panel containing a microcomputer and being connected to a power supply;
- a control panel connected to said system interconnection panel;
- a heating element connected to said system interconnection panel;
- and
- a pump for circulating water over said heating element.
