Patent ID: 8770490

Claim:
A thermostat for a climate control system, comprising: an electronic memory for storing at least three occupancy state set-points including an unoccupied temperature set-point, an occupied temperature set-point, and a sleep temperature set-point; and a microprocessor configured to: receive a first user input predefining, independently of any time period scheduled or schedulable for thermostat operation, one or more of the at least three occupancy state set-points; assign each of the one or more predefined occupancy state set-points to a corresponding one of at least three occupancy states including an unoccupied state, an occupied-awake state, and an occupied-asleep state; and receive a second user input assigning one or more of the at least three occupancy states to one or more time periods; wherein the microprocessor controls operation of the climate control system to maintain one of the pre-defined occupancy state set-points during any time period assigned the occupancy state corresponding to the one of the predefined occupancy state set-points; and wherein one of the occupancy states is selectable by a user for a plurality of time periods during the day.
