The present disclosure provides a method for operating a utility-powered HVAC system for conditioning inside air of a building. In an illustrative but non-limiting example, a nominal schedule is maintained by a local HVAC controller, where the nominal schedule has a number of days and one or more time periods for each of at least some of the days. The nominal schedule also has at least one setpoint associated with each of the time periods. The local HVAC controller is configured to accept manual input from a user via a user interface. The manual input may include accepting entry of a utility pricing schedule that corresponds to scheduled price changes of a utility. The utility pricing schedule may include at least one enhanced pricing time period. Entry of at least one utility price level setpoint offset may also be accepted to correspond to each of the enhanced pricing time periods. The nominal schedule may then be modified or overridden to include the utility pricing schedule, resulting in a utility pricing operating schedule. One or more HVAC units may then be controlled by the local HVAC controller in accordance with the utility pricing operating schedule.

1. A method for operating a utility-powered HVAC system for conditioning inside air of a building, the HVAC system having one or more HVAC units and a local HVAC controller having a user interface, the method comprising: maintaining in a memory of the local HVAC controller a nominal schedule, the nominal schedule having a number of days and one or more time periods for each of at least some of the days, the nominal schedule further having at least one setpoint associated with each of the one or more time periods;receiving manual input via the user interface of the local HVAC controller, the manual input including: accepting entry of a utility pricing schedule that corresponds to scheduled price changes of a utility, including at least one enhanced pricing time period;accepting entry of at least one utility price level setpoint offset to correspond to each of the at least one enhanced pricing time periods;modifying or overlaying the nominal schedule to include the utility pricing schedule, resulting in a utility pricing operating schedule; andcontrolling the one or more HVAC units with the local HVAC controller in accordance with the utility pricing operating schedule. 2. The method of claim 1, wherein the utility pricing schedule is provided by the utility and includes at least one recurring enhanced pricing time period. 3. The method of claim 2, wherein the at least one recurring enhanced pricing time recurs weekly. 4. The method of claim 2, wherein the utility pricing schedule includes at least two seasons, wherein the at least one recurring enhanced pricing time period corresponds to one of the two seasons. 5. The method of claim 1, wherein receiving manual input via the user interface includes accepting entry of a utility price level for each of the scheduled price changes of the utility. 6. The method of claim 5, further including accepting entry of at least one utility price level setpoint offset for each of the utility price levels. 7. The method of claim 1, further comprising: accepting entry of one or more utility price levels associating one of the utility price levels with each of the scheduled price changes of the utility;associating at least one utility price level setpoint offset with each of the utility price levels. 8. The method of claim 1, wherein the utility pricing operating schedule includes each of the enhanced pricing time periods such that one of the corresponding utility price level setpoint offsets is used to offset one of the setpoints associated with an overlapping time period of the nominal schedule to result in an operating setpoint used during the overlapping time period. 9. The method of claim 1, wherein the utility pricing operating schedule includes a pre-cooling time period. 10. The method of claim 1, further comprising: receiving via the user interface a manual selection of whether to enable or disable control in accordance with the utility pricing operating schedule; andcontrolling the one or more HVAC units with the local HVAC controller in accordance with the nominal schedule if manual selection to disable control in accordance with the utility pricing operating schedule is received. 11. The method of claim 1, wherein the user interface of the local HVAC controller includes a display screen and buttons, and wherein the receiving manual input is performed by a user interacting with the display screen and/or buttons. 12. The method of claim 11, wherein the display screen is a touchscreen, and at least one of the buttons is a touchscreen button. 13. The method of claim 1, wherein the local HVAC controller is a thermostat. 14. A method for operating a utility-powered HVAC system for conditioning inside air of a building, the HVAC system having one or more HVAC units and a thermostat, the method comprising: maintaining in a memory of the thermostat a nominal schedule, the nominal schedule having a number of days and one or more time periods for each of at least some of the days, the nominal schedule further having at least one setpoint associated with each of the one or more time periods;receiving manual input from a user of the thermostat of a utility pricing schedule that corresponds to scheduled price changes of a utility, wherein the utility pricing schedule includes at least one enhanced pricing time period with a corresponding utility pricing level selected from at least two utility pricing levels;receiving manual input from the user of the thermostat of at least one utility pricing level setpoint offset to correspond to each of the at least two utility pricing levels;modifying or overriding the nominal schedule with the utility pricing schedule to result in a utility pricing operating schedule, wherein for each of the at least one enhanced pricing time periods, the at least one utility pricing level setpoint offset that corresponds to the utility pricing level of the enhanced pricing time period is used to offset one of the at least one setpoints associated with one of the one or more time periods of the nominal schedule to result in an operating setpoint of the utility pricing operating schedule for the enhanced pricing time period; andcontrolling the one or more HVAC units with the thermostat in accordance with the utility pricing operating schedule. 15. The method of claim 14, wherein the utility pricing schedule includes at least one weekly utility pricing schedule, where the at least one weekly utility pricing schedule includes one or more recurring enhanced pricing time periods that recur weekly. 16. The method of claim 15, wherein the at least one weekly utility pricing schedule includes one or more weekly groups of days, each of the one or more weekly groups of days including one or more days, further wherein at least one of the one or more recurring enhanced pricing time periods recurs each day of one of the one or more weekly groups of days. 17. The method of claim 15, wherein the utility pricing schedule includes at least two seasons, wherein each of the at least one weekly utility pricing schedules is associated with one of the at least two seasons. 18. The method of claim 14, wherein the thermostat includes a touchscreen, and wherein the receiving manual input can be performed by a user interacting with the touchscreen. 19. A thermostat configured to operate a utility-powered HVAC system for conditioning inside air of a building, the HVAC system having one or more HVAC units, the thermostat comprising: a user interface configured to receive manual input from a user of a nominal setpoint schedule, as well as a utility pricing schedule that corresponds to scheduled price changes of a utility;a memory configured to retain the nominal schedule and the utility pricing schedule; andat least one output configured to issue operational commands to the one or more HVAC units of the HVAC system;wherein the nominal setpoint schedule includes a number of days and one or more time periods for each of at least some of the days, the nominal schedule further having at least one setpoint associated with each of the one or more time periods;wherein the utility pricing schedule includes at least one enhanced pricing time period with a corresponding utility pricing level setpoint offset; andwherein the thermostat is configured to modify or overlay the nominal setpoint schedule in accordance with the utility pricing schedule to result in a utility pricing operating schedule, and to control the one or more HVAC units in accordance with the utility pricing operating schedule. 20. The thermostat of claim 19, wherein the user interface includes a touchscreen, such that manual input can be performed by a user interacting with the touchscreen.
