ENVIRONMENTAL CONTROL
BACKGROUND OF THE INVENTION
[0001] Exemplary embodiments pertain to the art of environmental control devices and, more particularly, to a system and method for establishing activity based environmental control of a space.
[0002] Environmental controls have evolved over time from simple temperature based controls to more conventional programmable controls. Programmable controls allow users to set a particular temperature in an area for a particular time of day. More specifically, programmable controls or thermostats enable users to program a schedule of temperature set points for a fixed number of time periods over the course of a day. In some cases, a different schedule may be programmed for different days. Existing controls include rigid time periods. For example, a thermostat may include four sequential time periods, WAKE, AWAY, HOME, and SLEEP. That is, the time periods progress, in order, from WAKE through SLEEP. More specifically, the AWAY time period cannot be programmed for a time period that is earlier than the time period associated with WAKE; the HOME time period cannot be programmed for a time period that is earlier than the time period associate with AWAY; and the SLEEP control phase can not be programmed for a time period that is earlier than any of the other time periods. For each time period, the user may set a specific start time, and desired temperature. During each time period, the thermostat operates a heating/cooling system to establish the desired temperature.

DETAILED DESCRIPTION OF THE INVENTION
[0014] A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
[0015] With reference to FIG. 1, an environmental control system in accordance with the exemplary embodiment is indicated generally at 2. Environmental control arrangement 2 includes a programmable control unit 4. Programmable control unit 4 includes a housing 6 and a user input/output device shown in the form of a touch screen display 8 that allows a user to establish and view various environmental control parameters for one or more environmental control zones as will be detailed more fully below. Programmable control unit 4 also includes a controller 10 having a memory 11. Programmable control unit is operatively connected to a plurality of environmental control devices 12. Memory 11 that stores various programs for controller 10 as will be discussed more fully below. Environmental control devices 12 include a temperature control system 14, such as a gas furnace, air conditioner, and/or heat pump; a humidity control system 16; and an airflow control system 18. It should be understood that the number and type of environmental control devices can vary. Programmable control unit 4 is configured to establish desired environmental parameters, e.g., temperature, humidity, and/or airflow for a first environmental control zone 24 having a first sensor 26, and a second environmental control zone 28 having a second sensor 30. At this point it should be understood that while shown with touch screen display 8, programmable control unit 4 can be provided with other mechanisms that accept user inputs such as buttons or key pads in combination with a liquid crystal display (LCD) screen that displays current and desired temperature information. Also, while shown with an integrated controller, programmable control unit 4 could be operatively connected to a controller located remote from housing 6.
[0016] Each sensor 26, 30 provides environmental parameter data from respective ones of first and second environmental control zones 24 and 28 to programmable control unit 4. In accordance with the exemplary embodiment, a user is provided with an option of establishing activity based environmental control parameters for first and/or second environmental control zone 26, 28 as will be discussed more fully below. More specifically programmable environmental control 4 includes a plurality of activity registers 32-36 that are configured to store various environmental parameters, and a plurality of time period registers 40-44 that are associated with select ones of activity registers 32-36. At this point it should be understood that activity based environmental control should be understood to mean that a user can program various environmental factors for specific activities which are then assigned a desired time period. The user is not limited to selecting only a desired temperature for a series sequentially running time periods as provided in the prior art arrangements.
[0017] Reference will now be made to FIG. 2 in describing a method 60 of establishing activity based environmental control for programmable control unit 4. A user has an option of entering activity parameter data through either a question and answer mode as indicated in block 62 or directly into activity registers 32-36 as indicated in block 64. If directly inputting activity data, the user initially selects a first activity phase such as WAKE as indicated in block 70. At this point, the user establishes desired environmental control parameters for WAKE as indicated in block 72. For example, a user may select desired temperature, humidity, dehumidification, and/or fan options for WAKE such as shown in FIG. 3. After selecting the environmental control parameters, the user assigns or defines a time period for the activity phase as indicated in block 74. The time period may represent all or part of a day as will be detailed more fully below. The time period may be different from day to day as will also be described more fully below. In any case, assigning or defining a time period should be understood to include selecting a start time, establishing start and end times, or simply selecting an activity phase for an indefinite time period. At this point, the user has the option of selecting another activity in block 76. In accordance with one aspect of the exemplary embodiment, the user may set environmental control parameters for HOME, AWAY, SLEEP, and VACATION activity phases in addition to WAKE. The number of activity phases, and activity phase descriptions (labels) can vary. In addition, a user may be provided with an option of assigned unique labels to one or more of activity registers 32-36. After setting up each desired activity phase, method 60 is saved in memory 11 as a set of computer readable instructions in memory and subsequently selectively executed or run by controller 10 as indicated in block 80.
[0018] Reference will now be made to FIGS. 4-7 in describing various examples of activity based environmental control in accordance with the exemplary embodiment. As shown, a user has established five activity phases each having associated therewith environmental control parameters. FIG. 4 illustrates activity based control for Monday. On Monday, the user has established a time period for a single activity phase, namely HOME, to initiate at 6:00 am. As such, programmable control unit will selectively activate environment control system 12 to establish the desired environmental control parameters for HOME. For Tuesday, illustrated in FIG. 5, the user has assigned time periods to four activity phases, namely, WAKE, HOME, AWAY, and SLEEP. For Wednesday, illustrated in FIG. 6, the user has programmed different time periods for the WAKE, HOME, AWAY, and SLEEP user defined activity phases. Thursday, illustrated in FIG. 7 shows that the user has programmed three time periods, two for WAKE and HOME, and the third for VACATION. In this manner, the user can tailor desired environmental parameters to meet his/her individual needs for any given day. More over, the user can assign different time periods for each activity phase for each environmental control zone. For example, in environmental control zone 24, the user may assign 6:00 am to WAKE, but environmental control zone 28 can be assigned SLEEP, AWAY or HOME for the same time period. This provides the user even greater flexibility to establish comfortable, and or energy saving environmental parameters for a home.
[0019] At this point it should be understood that the exemplary embodiment provides a system for programming activity based environmental factors for one or more environmental control zones. Activity based programming allows a user to establish various environmental factors, e.g., temperature, humidity, air flow, for one or more activities. The user then has the flexibility to assign each activity to independent time periods in a 24-hour period, but to different time periods for each day of a week. In this manner, the user can easily establish desired comfort levels for his/her home.
[0020] While the invention has been described with reference to an exemplary embodiment or embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the claims.
