Abstract: Adaptive intelligent circulation control methods and systems are used to help increase the comfort and/or reduce energy usage and equipment wear. In one illustrative embodiment, the circulation and/or ventilation time is adjusted based on one or more environmental conditions inside or outside the building structure. In another illustrative embodiment, the circulation and/or ventilation time may be adjusted based on the current time of day, current time of year, and/or the current schedule period. In another illustrative embodiment, the circulation and/or ventilation time is randomized over time. The start time, end time, and/or length of a circulation and/or ventilation cycle may be randomly set.

Abstract: A controller equipped with a user interface having a separate schedule review mode, including methods of accessing and/or programming such devices, are disclosed. The controller may include a user interface that can be utilized to initiate a scheduling routine having a separate schedule review mode for displaying one or more schedule parameters of the controller without initiating the editing mode. An illustrative method of accessing a schedule on a controller coupled to a user interface may include the steps of initializing a scheduling routine within the controller, initiating a schedule review mode within the controller, displaying one or more schedule parameters for at least one period on the user interface, and exiting the scheduling routine. One or more of the schedule parameters can be modified, if desired, by initiating a separate editing mode within the controller.

Abstract: A controller and a method of programming a schedule of a controller having a user interface, the schedule having a number of schedule parameters, the method including the steps of: providing one or more interview questions to a user via the user interface; accepting one or more user responses to the one or more interview questions from the user via the user interface; and modifying one or more of the schedule parameters based on the user responses provided by the user interface.

Abstract: A programmable controller such as an HVAC controller that provides a confirmation message to a user indicating that a parameter that has been modified by the user has been or will be saved. Such a confirmation message may help assure a user that their program modifications have been accepted and/or saved by the controller, thereby reducing the anxiety some users feel when programming such controllers.

Abstract: A method of modifying a programmable schedule for a controller and a controller are disclosed having a user interface. The method includes the steps of providing, simultaneously or sequentially, two or more schedule override choices to a user via the user interface, accepting a selection of one of the two or more schedule override choices from the user via the user interface, and modifying temporarily the schedule based on the user responses provided by the user interface.
