HVAC controller with indoor air quality scheduling
First Claim
1. An HVAC controller configured to control one or more components of an HVAC system of a building, the HVAC controller comprising:
- a user interface including a display;
a memory;
a programmable operating schedule including two or more time periods and one or more temperature set points for each of the two or more time periods, the programmable operating schedule stored in the memory;
an I/O block for sending and/or receiving signals to and/or from the one or more components of the HVAC system including one or more of a heating unit, an air conditioner unit, a humidifier unit, and a dehumidifier unit;
a controller coupled to the user interface, the memory, and the I/O block, the controller configured to generate one or more signals to control one or more components of the HVAC system in accordance with the programmable operating schedule, the controller further configured to allow a user to program at least a first time period of the two or more time periods of the programmable operating schedule to control at least one of the humidifier unit and the dehumidifier unit differently than during at least one other of the two or more time periods of the programmable operating schedule; and
wherein the controller is configured to allow a user to program the programmable operating schedule by allowing the user to;
select a set point for the at least one of the humidifier unit and the dehumidifier unit;
identify at least a first time period of the two or more time periods of the programmable operating schedule to not-operate the at least one of the humidifier unit and the dehumidifier unit in accordance with the selected set point, and to identify at least a second time period of the two or more time periods of the programmable operating schedule to operate the at least one of the humidifier unit and the dehumidifier unit in accordance with the selected set point; and
wherein a plurality of the two or more time periods are displayed on a common screen on the display and the at least first time period is identified by selection of the first time period from the plurality of displayed time periods on the display, and the at least second time period is identified by non-selection of the second time period from the plurality of displayed time periods on the display;
wherein the selection and non-selection of each of the plurality of the two or more time periods to operate and not operate the at least one of the humidifier unit and the dehumidifier unit in accordance with the selected set point are determinable from the common screen.

Abstract
An HVAC controller, such as a thermostat, may be configured to allow a user to set and/or select schedule time period in which one or more indoor quality units (e.g. humidification, dehumidification, ventilation, etc.) will or will not operate, and/or will operated but using different settings. In some cases, the schedule time periods available for selection may correspond to the time periods of a programmable temperature schedule of the HVAC controller, but this is not required. In some instances, the HVAC controller may allow a user to select which indoor air quality units will or will not operate, and/or what settings the indoor air quality units will operate, during a user'"'"'s vacation.

9. An HVAC controller configured to control one or more components of an HVAC system of a building, the HVAC controller comprising:
-
a user interface including a display; a memory; an I/O block for sending and/or receiving signals to and/or from the one or more components of the HVAC system, including one or more of a heating unit, an air conditioning unit, and one or more indoor air quality components; and a controller coupled to the user interface, the memory, and the I/O block, the controller is configured to display a selector for each of the one or more indoor air quality components of the HVAC system on a common screen on the display and to allow a user to select which of the one or more indoor air quality components are to operate in a vacation mode during a user'"'"'s vacation schedule by selecting the corresponding selector on the display and which of the one or more indoor air quality components are to operate in a normal mode during a user'"'"'s vacation schedule by non-selection of the corresponding selector on the display, wherein the selection and non-selection of the corresponding selectors are determinable from the common screen. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of controlling an HVAC system including one or more of a heating unit, an air conditioner unit, a humidifier unit, and a dehumidifier unit, the method comprising:
-
receiving two or more temperature set points corresponding to two or more time periods related to a user'"'"'s schedule at the user interface of a thermostat; displaying a selector for each of the two or more time periods on a common screen of a display of the user interface of the thermostat, wherein non-selection of one or more of the selectors for the two or more time periods displayed on the common screen identifies the time periods during which the humidifier unit or the dehumidifier unit will operate in accordance with a set point; and receiving a user'"'"'s input at the user interface of the thermostat to select the selector for at least one but less than all of the two or more time periods of the user'"'"'s schedule during which at least one of the humidifier unit and the dehumidifier unit will not operate in accordance with any set point, wherein the selection and non-selection of the corresponding selectors are determinable from the common screen. - View Dependent Claims (17, 18)
