Abstract
A controller controls operation of a HVAC&R device, bringing the temperature inside a structure from a first temperature to a second temperature at a predetermined time each day. Sensors sense the temperature both inside and outside the structure. A recovery time is calculated based upon a previously calculated air treatment rate of temperature recovery for the HVAC&R device to drive the temperature of the structure through a temperature change, the recovery time calculation being obtained by multiplying the difference between the sensed temperature inside the structure and the second temperature by the previously calculated air treatment rate. A correction factor is calculated based upon a relationship between the sensed outside temperature and a previously sensed outside temperature, the correction factor being added to obtain a corrected recovery time. The HVAC&R device is initiated at a time defined by the predetermined time subtracted from the corrected recovery time.
