Abstract
Thermostatic control of heating, as for a pool or spa, involves use of a heat source including a main heat generator and a mounting body, and includes: (a) a main high limit thermostat mounted in such relation to the body as to receive heat therefrom. (b) a thermal isolator plate operatively sandwiched between the body and thermostat, and (c) a heat conduction plate operatively sandwiched between the body and thermostat, there being an auxiliary heat source located to separately heat the heat conduction plate to cause heat flow to the thermostat, (d) the thermostat connected to interrupt operation of the main heat generator and operation of said auxiliary heat source in response to heating of the thermostat to a predetermined high temperature.

In combination with heat source means including a main heat generator and a mounting body,
- (a) a main high limit thermostat mounted in such relation to said body as to receive heat therefrom,
- (b) a thermal isolator plate operatively sandwiched between said body and said thermostat, and
- (c) a heat conduction plate operatively sandwiched between said isolator plate and said thermostat, there being an auxiliary heat source located to separately heat said heat conduction plate to cause heat flow to said thermostat, said isolator plate, heat conduction plate and thermostat being mounted in closely stacked together sequence and in heat transfer relation on said body, the auxiliary heat source carried by said heat conduction plate.
