Control unit with automatic setback capability
First Claim
1. A device comprising:
- a memory configured to store a preexisting schedule;
one or more processors configured to perform operations comprising;
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;
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, wherein;
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.

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.

13. A device comprising:
-
a memory storing a preexisting schedule; one or more processors configured to perform operations comprising; controlling temperature within a conditioned enclosure according to a setpoint temperature, an initial value of the setpoint temperature being from a preexisting schedule and representing a temperature suitable for when one or more persons are occupying the conditioned enclosure; periodically accessing occupancy data indicating occupancy within the enclosure; periodically updating the setpoint temperature upon expiration of a predetermined time interval during which no occupancy has been detected, the updated setpoint temperature requiring substantially less energy to maintain than the initial value of the setpoint temperature; and periodically modifying the predetermined time interval based at least in part on received manual settings that indicate occupancy following the updating the setpoint temperature. - View Dependent Claims (14, 15, 16, 17, 18, 19)
