Abstract
A thermostat receives requests to enter into setback modes of operation whereby at least one setpoint normally used by the thermostat is changed. The thermostat is operative to compute the integral of change in setpoint temperature over time during each setback mode of operation. The thermostat is also operative to maintain a running total of such computed integrals of change in setpoint temperature over time in order to respond to any request for such computed integrals. The thermostat is furthermore operative to set the total of such computed integrals of change in setpoint temperature over time equal to zero in response to a request to clear the total of such computed integrals of change in setpoint temperature over time. The thermostat will furthermore compute the integral of temperature offset occurring over any time left in any present setback mode of operation after implementing a requested clearing so as to thereby initiate the computation of a new running total of computed integrals of temperature offset occurring over time spent in setback modes of operation that are implemented after the clearing.
