Abstract
An HVAC controller with setpoint recovery with utility time of day pricing. In one illustrative embodiment, the HVAC controller may include a nominal programmable schedule and a utility pricing schedule. The utility pricing schedule may correspond to scheduled price changes of a utility, including one or more enhanced pricing time periods each having corresponding one or more enhanced pricing time period setpoints. The HVAC controller may establish or modify an enhanced pricing setpoint recovery schedule based at least in part upon the nominal schedule and the utility pricing schedule, and may control one or more HVAC units in accordance with the setpoint recovery schedule. In some instances, the HVAC controller may identify recovery opportunities based at least in part upon the nominal schedule and the utility pricing schedule.
