An electronic system and method are disclosed for controlling a measured temperature during a sequence of time intervals, in accordance with a sequence of selected reference temperatures, each corresponding to one of the intervals. The values of the reference temperatures are programmable and changeable by the user. The system and method can be used to establish thermostatic control in conformity with a referenced temperature that varies throughout the day, for example, hour by hour. The system also provides for using different sequences of reference temperatures on different days.

A system for controlling a measured temperature during a sequence of time intervals in accordance with a sequence of selected reference temperatures, each corresponding to one of the intervals, comprising: means for storing a plurality of digital numbers, each representing a value of one of the reference temperatures; means connectable to respond to a reference frequency source for repeatedly generating a digital number representative, at each generation, of the present time of day; means for storing a digital number representative of a value of hysteresis; updating means for repeatedly determining, from said time of day number, when one of said intervals embraces the present time and identifying the one of said reference temperatures corresponding to said embracing interval and for storing, as a current reference temperature value, a digital number representing the value of said identified reference temperature, said updating means including means for determining that as soon as said present time exceeds the last interval in said sequence, said time becomes embraced by the first interval in the sequence; means for displaying selected ones of said digital numbers; means connectable to be responsive to a sensor of said measured temperature for generating an electrical signal representation of said measured temperatures; and comparison means responsive to said signal representation, to the current reference temperature number, and to the hysteresis number, for repeatedly generating control signals suitable for controlling thermal means affecting said measured temperature.
