Abstract

Methods and apparatuses for magnetically detecting a temperature change for thermostat control thereof are disclosed. A thermostat control device can be configured to include at least one bi-metallic strip that is configured to experience a change in angular position in response to a temperature change. The thermostat control device is generally associated with a Hall sensor, which includes a plurality of magnets that can experience movement relative to the Hall sensor in response to the change in the angular position of the bi-metallic strip. The temperature change can then be automatically and/or electrically detected in response to the movement of the magnets, wherein the temperature change is utilized for thermostat control thereof.
