Abstract
A device includes a memory configured to store a preexisting schedule and one or more processors configured to perform operations including controlling a temperature within an enclosure according to a first setpoint, wherein the first setpoint is from the preexisting schedule and represents a temperature for when the enclosure is occupied. The operations also include accessing occupancy data indicating occupancy within the enclosure and automatically changing the first setpoint to a second setpoint upon expiration of a predetermined time interval during which no occupancy has been detected. The second setpoint requires less energy to maintain than the first setpoint, and the predetermined time interval is modified based at least in part on received manual settings that indicate occupancy following the changing to the second setpoint.
