1. A method for controlling temperature in a conditioned enclosure comprising:

  • controlling temperature within the conditioned space according to a first setpoint, the first setpoint being from a preexisting schedule and representing a temperature suitable when one or more persons are occupying the conditioned space;

    receiving data reflecting one or more occupancy sensors adapted to detect occupancy within the conditioned enclosure; and

    automatically changing the setpoint temperature to a second setpoint upon expiration of a predetermined time interval during which no occupancy has been detected, the second setpoint requiring substantially less energy to maintain than the first setpoint.
