HVAC controller that selectively replaces operating information on a display with system status information
An HVAC controller is described that is configured to be more intuitive and user friendly to program and operate than convention HVAC controllers. In some instances, the HVAC controller may include a touch screen interface that provides greater flexibility in displaying information to the user and/or soliciting information from the user.
1. An HVAC controller configured to control one or more components of an HVAC system, the HVAC controller comprising:
a touch screen dot matrix display;
a controller in communication with the touch screen dot matrix display and configured to operate an algorithm that at least partially controls the one or more components of the HVAC system, the controller is further configured to display a first image that includes a first set of information in a first display region of the touch screen dot matrix display and a second image that includes a second set of information in a second display region of the touch screen dot matrix display, the controller also configured to replace the second image in the second display region with a third image that indicates one or more system status conditions; and
wherein the third image defines an information button on the touch screen dot matrix display, wherein when the information button is touched, more information is displayed on the touch screen dot matrix display that relates to the one or more system status conditions.
2. The HVAC controller of claim 1 , wherein the more information is displayed, at least in part, in the first region of the touch screen dot matrix display.
3. The HVAC controller of claim 1 , wherein when the information button is touched, a notification screen is displayed which provides the more information that relates to the one or more system status conditions.
4. The HVAC controller of claim 3 , wherein the notification screen includes a scroll feature that allows a user to scroll through each of the one or more system status conditions.
5. The HVAC controller of claim 1 , wherein the controller is configured to display a menu driven interface on the touch screen dot matrix display having a home screen, wherein the first image, second image and third image are all displayed on the home screen.
6. The HVAC controller of claim 1 , wherein the first image in the first display region is unaffected by the second image being replaced with the third image in the second display region.
7. The HVAC controller of claim 1 , wherein the controller replaces the second image in the second display region with the third image when the controller detects the occurrence of one or more system status events.
8. The HVAC controller of claim 1 , wherein the one or more system status conditions includes an equipment warning message.
9. The HVAC controller of claim 8 , wherein the equipment warning message informs a user that one or more components of the HVAC system is malfunctioning.
10. The HVAC controller of claim 1 , wherein the one or more system status conditions includes an equipment maintenance message.
11. The HVAC controller of claim 10 , wherein the equipment maintenance message pertains to one or more of an air filter change, an air filter cleaning, a humidifier pad change and a UV lamp replacement.
12. The HVAC controller of claim 1 , wherein the second set of information includes one or more of a date, a time, an equipment status and an outdoor weather parameter.
13. The HVAC controller of claim 1 , wherein the first set of information includes one or more of a current indoor temperature, a temperature set point, an indoor humidity reading and schedule information.
14. An HVAC controller configured to control one or more components of an HVAC system, the HVAC controller comprising:
a touch screen dot matrix display; and
a controller in communication with the touch screen dot matrix display, the controller configured to operate an algorithm that at least partially controls the one or more components of the HVAC system;
the controller is further configured to display a menu driven interface on the touch screen dot matrix display having a home screen, wherein the controller displays a number of parameters on the home screen;
the controller is also configured to detect the occurrence of a system status event, and in response, the controller replaces at least one of the parameters on the home screen with an information button, that when touched, causes information to be displayed on the touch screen dot matrix display that is related to the detected system status event.
15. The HVAC controller of claim 14 , wherein when the information button is touched, the controller replaces at least a majority of the parameters on the home screen with a notification screen that includes at least some of the information related to the detected system status event.
16. The HVAC controller of claim 15 , wherein the notification screen includes a scroll feature that allows a user to scroll through a number of detected system status events.
17. A method for alerting a user to a system status condition of a thermostat, comprising:
displaying one or more parameters on a touch screen dot matrix display;
detecting a system status condition; and
replacing at least one of the parameters on the home screen with an information button.
18. The method of claim 17 further comprising:
in response to a user touching the information button on the home screen, displaying information on the touch screen dot matrix display that is related to the detected system status condition.
19. The method of claim 18 , wherein if more than one system status conditions have been detected, displaying a notification screen includes a scroll feature that allows a user to scroll through and view information related to a number of detected system status conditions.
