ABSTRACT:
An improved temperature sensing and control apparatus for a spa is described, which control apparatus is located at the spa. A switching means is disposed in the series electrical circuit of a water heating mechanism. The switching means is remotely controlled as a function of the water temperature and operates in the low voltage and low current range, thereby minimizing a safety hazard.
