Patent Issued for Programmable Thermostat

July 23, 2014

By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventor Drew, David Scott (St. Louis, MO), filed on August 18, 2010, was published online on July 8, 2014.

The patent's assignee for patent number 8770490 is Emerson Electric Co. (St. Louis, MO).

News editors obtained the following quote from the background information supplied by the inventors: "This section provides background information related to the present disclosure which is not necessarily prior art.

"Many digital programmable thermostats allow for programming time and temperature settings for various days of the week. However, the typical programmable thermostat requires entry of temperature settings for numerous different time periods that the user must select, which entails pressing the necessary series of different buttons to program the thermostat. If the user is faced with a thermostat having a daunting series of different buttons to press and screens to progress through to enter such temperature settings, the user is not likely to realize any energy savings due to the user's apprehension towards programming the thermostat."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventor's summary information for this patent: "This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

"Various embodiments are disclosed of a thermostat for controlling the operation of a climate control system to adjust the temperature of a space to maintain a select predefined temperature set-point associated with a given time period during the day. One embodiment of a thermostat for a climate control system includes an electronic memory in which at least three occupancy settings are stored. The at least three occupancy settings include a pre-defined unoccupied temperature set-point associated with an unoccupied state, a pre-defined occupied temperature set-point associated with an occupied-awake state and a pre-defined sleep temperature set-point associated with an occupied-asleep state. The thermostat further includes a microprocessor configured to communicate with the electronic memory, and to establish at least three time periods during the day. The microprocessor is configured to assign to each of the time periods one of at least three user-selectable occupancy states including an unoccupied state, an occupied-awake state and an occupied-asleep state. Accordingly, the microprocessor controls operation of the climate control system to maintain the unoccupied temperature set-point during any time period assigned the unoccupied state, and to maintain the occupied temperature set-point during any time period assigned the occupied-awake state, and to maintain the sleep temperature set-point during any time period assigned the occupied-asleep state.

"Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure."
