  • Tamper proof thermostat that limits temperature controls
    Patent number: 9201431
    Abstract: A tamper proof thermostat has a predetermined and permanently fixed maximum heating temperature and minimum cooling temperature associated with each portion of a preset schedule. A user may only select temperatures below the maximum heating temperature or above the minimum cooling temperature. The thermostat further receives a dedicated time signal broadcast from an external source. The broadcast is the exclusive source of time information for the thermostat, ensuring that a user is not able to manipulate the preset schedule.
