ABSTRACT:
A solid state thermostatic device having two programmable temperature control circuits, one of which, when energized, serves to maintain a comfort controlled region at a high temperature level and the other of which, when energized, serves to maintain the comfort controlled region at a lower level. Two clocks are contained within the device for recording real time and for generating an alarm signal when a set time stored in the clock is reached. The two alarm signals generated by the clocks electrically energize the control circuits to regulate the temperature in the comfort control region at the programmed levels during a selected period of time. A digital display is also provided for supplying a visual readout of selected system related parameters including the real time and the stored time contained in each clock and the temperature within the comfort controlled region both in degrees Celsius and Fahrenheit. The display also permits real time and alarm time to be accurately and conveniently set into the clocks.
