Abstract: Controllers and systems for displaying servicing information via a display unit are disclosed. A controller in accordance with an illustrative embodiment of the present invention may include an interface for programming a service event display mode in the controller, and a display unit configured to display servicing information when a service event is detected by the controller. An event such as the triggering of a service indicator or the expiration of an equipment service event timer may cause the controller to display servicing information on the display unit, informing the user that servicing may be necessary or is recommended.

Abstract: A system and method for regulating the operation of first and second temperature modification sources for heating or cooling a building structure is provided. The system switches between the first and second temperature modification sources based on conditions other than just outside temperature.

Abstract: A controller equipped with a user interface having multiple-day programming capabilities, including methods of programming such devices, are disclosed. The user interface may include one or more menus or screens that can be used to program a schedule for one or more selected days during the week. An illustrative method of programming the controller may include the steps of entering a scheduling routine, selecting multiple days for schedule modification, changing the schedule parameters for one or more periods during the selected days, and then exiting the scheduling routine.

Abstract: Electronic devices that include batteries can be adapted to provide one or more indications of a low battery condition. An electronic device such as a controller can include a battery and can be adapted to determine a first low battery condition. A first indication can be provided in response to the first low battery condition. In some cases, a second battery condition can be determined and a second indication can be provided in response to the second battery condition. The indications provided to the user can be made progressively more noticeable over time, until the battery is replaced.
