The invention provides a thermostat control display having a programming function button, day of the week icons, a table for displaying time and temperature parameters and a graphical highlight pattern that links the table and the day of the week icons. The button, icons and table comprise touch sensitive areas adapted to activate a predetermined display response. Upon selection of a day of the week icon the graphical highlight pattern will be extended to surround the selected day of the week icon so that the table depicting temperature and time parameters to be assigned to the selected day of the week are visually linked to the selected day of the week.
