A microcomputer controlled digital thermostat has a two-digit display which normally displays room temperature and a plurality of function and temperature keys for storing control information in the microcomputer. The function keys include a TIME SET key, a HEAT SET key, an AC SET key, and an AC OFF key. The temperature keys include keys for each of a plurality of temperature ranges such as 59.degree.-59.degree. F., 60.degree.-69.degree. F., and 80.degree.-89.degree. F. Time and temperature settings are entered and stored in registers of the microcomputer by a slew entry arrangement through use of the function keys and temperature keys, together with the display. Recall of the stored settings is provided by rapidly contacting the function keys.
