Abstract
A multistage thermostat is operated by comparing the thermostat setpoint and the sensed temperature over a continuous series of discrete intervals of time. When a sudden change occurs between the sensed temperature and the setpoint, the magnitude of this change is evaluated in a comparator means and if necessary the system is reset to compensate for the change to operate in the most efficient manner. The adjustment of a constant supplied to an integrating circuit that forms part of a signal processing circuit means for the thermostat means provides the adjustment when the predetermined level of change is made.
