AAT-106 ABSTRACT OF THE DISCLOSURE A thermostatic controller system for a building heating and/or cooling system (furnace) includes a stored program of desired temperatures which are to be attained within the building at predetermined times within a repetitive time cycle, such as a day. Differing environmental conditions externally of the build- ing result in differing rates of change of temperature within the building upon operation of the furnace. In order to determine the optimum time to switch the system on to meet the next pro- grammed increased temperature, the furnace is switched on and then off a short period of time later and the temperature change which results in the building as a result of that transient operation is measured. The time at which the furnace must be switched to attain the next programmed temperature is then determined as a function of the rate of temperature change as determined by the transient switching and the difference between the instantaneous and the future programmed temperature. Alternatively, the controller may calculate the rate of temper- ature change each time the furnace is turned on for normal building temperature modification and use the last stored value of that rate in the turn-on time calculation. The system attains an energy efficiency exceeding that of conventional thermostat systems.
