1. A thermostat for use with at least one in-floor heating element, the thermostat comprising:
a housing;
a heating element control circuit disposed within the housing, the heating element control circuit to cause an in-floor heating element to electrically couple to an alternating current power source;
memory disposed within the housing, the memory configured to store at least one predefined AC voltage rating representing an AC voltage rating for the in-floor heating element;
a first power measurement circuit disposed within the housing, the first power measurement circuit configured to detect a voltage of the alternating current power source; and
a controller disposed within the housing, the controller comprising a voltage monitoring circuit configured to detect an AC voltage rating mismatch based on a comparison of the detected voltage of the alternating current power source with the predefined AC voltage rating prior to energizing the in-floor heating element.
