A thermostat temperature programming display system for a digital thermostat that provides a graphical illustration of the relationship between the heating, cooling, and ambient temperatures is provided. This display system illustrates this relationship as digital markers along a linear temperature set point line on the display. As a set point is varied, the digital marker moves along the set point line. The heating and cooling set point markers are bounded by one another in a variable relationship based on a user defined dead band temperature during an automatic change over mode of operation. Only an appropriate marker is illustrated on the set point line based on the operating mode of the thermostat.
