Abstract: The present invention provides systems and methods for temperature control in refrigeration systems, such as beverage coolers, and heating systems, such as coffee dispensers. In an embodiment of the present invention, a control unit of a refrigeration system in accordance with the present invention receives and records activity data such as door openings and/or human presence detection in the vicinity of the refrigeration system, and then establishes the beginning and end times of an energy saving mode for the refrigeration system over a period of time, such as a week. The control unit calculates the time to restart the compressor cycle at the end of the energy saving mode so that the product will be at the correct temperature at the time of first usage. As part of the energy saving function, the lamps and fans in the refrigeration system are controlled independently by the control unit according to the activity data.

Abstract: A method for protecting an electrical device includes monitoring a line voltage to detect a high voltage condition such that the voltage is above a predetermined voltage range, and monitoring the line voltage to detect a low voltage condition such that the voltage is below the predetermined range. The method also includes electrically isolating the electrical device such that the electrical device does not receive electricity when at least one of a high voltage condition and a low voltage condition is detected.

Abstract: A method for operating a temperature controlled device includes detecting a human presence status and controlling a temperature of the temperature controlled device based upon the detected status.

Abstract: A method for assembling a control for use with a cooling device includes providing an attached control that is configured to control the cooling device, and installing a wireless interface in the attached control.
