Abstract

An HVAC controller may include a user interface, along with a memory for storing a recurring programmable schedule having two or more time periods. The user interface may be configured to allow manual modification by a user of the recurring schedule stored in the memory, wherein the user can associate an HVAC-off control mode with any of the two or more time periods. In the HVAC-off control mode, the HVAC controller may not cycle the HVAC unit on regardless of the temperature of the air in the inside space. The HVAC controller further may include an output that is configured to issue operational commands to the HVAC unit in accordance with the programmable schedule.

Claims

1. An HVAC controller configured to control an HVAC unit for conditioning air of an inside space, comprising:

a user interface configured to allow manual modification by a user of a recurring schedule having two or more time periods, wherein the user can associate an HVAC-off control mode with any of the two or more time periods of the recurring schedule, wherein the HVAC-off control mode does not have an associated set point temperature, and when in the HVAC-off control mode, the HVAC controller does not cycle the HVAC unit on regardless of the temperature of the air in the inside space;

a memory configured to retain the recurring schedule; and

an output configured to issue operational commands to the HVAC unit in accordance with the recurring schedule.

2. The HVAC controller of claim 1, wherein the recurring schedule is a weekly recurring schedule.

3. The HVAC controller of claim 1, wherein the user can associate an HVAC-on control mode with any of the two or more time periods.

4. The HVAC controller of claim 1, wherein the user can associate an HVAC-on control mode with any of the two or more time periods, wherein the HVAC-on control mode may be one of an HVAC-on-heat control mode, an HVAC-on-cool control mode, and an HVAC-on-auto changeover control mode.

5. The HVAC controller of claim 4, wherein the HVAC controller is configured to command the HVAC unit via the output to condition the air of the inside space in accordance with one or more setpoints during time periods associated with any of the HVAC-on control modes.

6. The HVAC controller of claim 1, wherein the output includes an infrared emitter.

7. The HVAC controller of claim 1, wherein the HVAC-off mode may be disabled via a configuration setting.
