A thermostat is programmable by entering input through a large-format touch-screen display. The touch-screen display displays different sets of icons depending on the mode the thermostat is in. A set of icons is displayed in one mode that allows the user to put the thermostat in a temporary operating mode. Another set of icons is displayed when programming the thermostat. Displaying several sets of icons at once allows a user to quickly and intuitively operate the thermostat, which in turn facilitates using energy-saving functions of the thermostat.
