Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
186 words
A temperature controlling apparatus for use in conjunction with spas, comprising thermostat means mounted adjacent a water heating apparatus, temperature selecting means mounted remote from said thermostat means and adjacent to a side of a spa, and cable drive means connected between said thermostat means and said temperture selecting means such that said thermostat means is selectively driven by said temperature selecting means via said cable drive means, said cable drive means includes at least first and second sheaves and elongated cable means extending between said first and second sheaves to provide mutual rotational motion of said sheaves, each of said first and second sheaves includes a pair of grooves therein for receiving said elongated cable means, said elongated cable means includes a pair of separate driving cables, each of said separate driving cables is associated with a different one of said pair of grooves in said first and second sheaves, said first sheave is coupled to said thermostat means, said second sheave is coupled to said temperature selecting means, and fiber optic cable means extending from said water heating means to said temperature selecting means.
Claim 2
Dependent Claim
