Abstract

A programmable HVAC controller that include a controller and a touch screen user interface is configured to control one or more pieces of HVAC equipment in accordance with a programmable schedule. In some instances, the controller of the programmable HVAC controller is programmed to define a number of columns on the touch screen display, such that a selected day of the programmable schedule may be visually represented across two or more adjacent columns of the touch screen display, with the selected day of the programmable schedule beginning in a first column and extending across and into a second adjacent column of the touch screen display. The controller may be programmed to monitor the touch screen display and allow a user to set a start time and/or an end time of a time period of the selected day of the programmable schedule by touching the first column and/or the second column of the touch screen display.
