Programmable thermostat

摘要

A thermostat for a climate control system includes an electronic memory in which at least three occupancy settings are stored. The occupancy settings including a pre-defined unoccupied temperature set-point associated with an unoccupied state, a pre-defined occupied temperature set-point associated with an occupied-awake state and a pre-defined sleep temperature set-point associated with an occupied-asleep state. The thermostat's microprocessor is configured to communicate with the memory, and to establish at least three time periods during the day. The microprocessor assigns to each time period one of at least three user-selectable occupancy states including an unoccupied state, an occupied-awake state and an occupied-asleep state. The microprocessor controls operation of the climate control system to maintain the unoccupied temperature set-point during any time period assigned the unoccupied state, the occupied temperature set-point during any time period assigned the occupied-awake state, and the sleep temperature set-point to any time period assigned the occupied-asleep state.

1. 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; andreceive 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.
