HVAC SCHEDULE WITH DESIGNATED OFF PERIODS
First Claim
1. A method for operating an HVAC system, the HVAC system having an HVAC unit for conditioning inside air of a building and an HVAC controller for controlling the HVAC unit, the method comprising:
- sensing a temperature of the inside air of the building;
maintaining in the memory of the HVAC controller a recurring schedule having a number of time periods, the recurring schedule having a control mode associated with at least two of the number of time periods, at least one of the time periods being associated with an HVAC-off control mode in which the HVAC unit does not condition the inside air of the building regardless of the sensed temperature of the inside air, and at least another one of the time periods being associated with an HVAC-on control mode in which the HVAC unit controls the sensed temperature of the inside air of the building in accordance with one or more setpoints; and
controlling the HVAC unit with the HVAC controller in accordance with the recurring schedule.

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.
