Abstract

Methods and systems for setting up HVAC controllers for a particular installation site are disclosed. In an example, an HVAC controller may be configured to control at least part of an HVAC system in accordance with an algorithm that includes equipment information pertaining to operation of the specific HVAC equipment forming the HVAC system as well as comfort information such as desired temperatures. In some cases, the HVAC controller may be configured to enable display of certain of the equipment information in a read-only fashion, and in some cases, certain of the equipment information that would be of interest to an building inspector.

First claim

What is claimed is:

1. An HVAC controller configured to control at least part of an HVAC system of a building, the HVAC controller comprising:
a controller configured to operate an algorithm that at least partially controls the HVAC system of the building, the algorithm referencing:
a plurality of equipment setup parameters that setup the algorithm to control the particular HVAC equipment that is used in the HVAC system of the building, the plurality of equipment setup parameters including ventilation related equipment setup parameters and non-ventilation related equipment setup parameters; and
one or more comfort parameters that define one or more comfort set points used by the algorithm when controlling the at least part of the HVAC system of the building;

a user interface operably coupled to the controller;
the controller configured to enter a setup mode, wherein the setup mode is configured to receive via the user interface edits to a plurality of parameter values each corresponding to one of the plurality of equipment setup parameters;
the controller further configured to accept via the user interface a review request to enter a read-only review mode, the read-only review mode configured to provide a review of a predetermined smaller subset of the plurality of equipment setup parameters and their corresponding parameter values, the predetermined smaller subset of the plurality of equipment setup parameters including the ventilation related equipment setup parameters but not the non-ventilation related equipment setup parameters, wherein the parameter values of the predetermined smaller subset of the plurality of equipment setup parameters cannot be edited without exiting the read-only review mode;
in response to the accepted review request, the controller is configured to provide on the user interface a read-only display of the predetermined smaller subset of the plurality of equipment setup parameters and their corresponding parameter values; and
the controller is further configured to operate the algorithm referencing the plurality of parameter values of the plurality of equipment setup parameters including the ventilation related equipment setup parameters and the non-ventilation related equipment setup parameters when controlling the at least part of the HVAC system of the building.

2. The HVAC controller of claim 1 , wherein the controller is configured to display on a single screen whether the ventilation related equipment setup parameters are correctly configured to meet a predetermined building code standard.

3. The HVAC controller of claim 1 , wherein the ventilation related equipment setup parameters comprise one or more of a run time percentage, a ventilation type, a ventilation rate, a number of bedrooms, a building square footage and a ventilation priority type.

4. The HVAC controller of claim 3 , wherein the ventilation priority type comprises a hi temperature lockout, a low temperature lockout and/or a high dew point lockout.

5. The HVAC controller of claim 1 , wherein the plurality of comfort parameters comprise one or more of a heating set point, a cooling set point, a heating set point schedule, a cooling set point schedule, a humidity set point, and an air quality set point.

6. The HVAC controller of claim 1 , wherein providing the read-only display on the user interface comprises providing a sequence of read-only display screens each for displaying one of the predetermined smaller subset of the plurality of equipment setup parameters and the corresponding parameter value.

7. The HVAC controller of claim 1 , wherein the controller is configured to operate the algorithm referencing the one or more comfort set points defined by the one or more comfort parameters when controlling the at least part of the HVAC system of the building.

8. The HVAC controller of claim 1 , wherein the controller is configured to display on the user interface a setup menu in the setup mode that allows a user to enter, and the controller to receive, edits to one or more of the plurality of parameter values corresponding to the plurality of equipment setup parameters.

9. The HVAC controller of claim 1 , wherein the controller is configured to display on the user interface an edit menu in the setup mode that allows a user to edit one or more of the plurality of parameter values corresponding to the plurality of equipment setup parameters.

10. The HVAC controller of claim 1 , wherein the controller is configured to display on the user interface a review menu in the review mode that allows a user to review in the read-only review mode the predetermined smaller subset of the plurality of equipment setup parameters and their corresponding parameter values without reviewing the plurality of equipment setup parameters that are not part of the predetermined smaller subset of the plurality of equipment setup parameters.

11. An HVAC controller configured to control at least a portion of an HVAC system of a building, the HVAC controller comprising:
a touch screen display;
a memory for storing:
a plurality of equipment setup parameters that setup the HVAC controller to control the particular HVAC equipment that is used in the HVAC system of the building, including ventilation related equipment setup parameters and non-ventilation related equipment setup parameters; and
one or more comfort parameters that define one or more comfort set points used by the HVAC controller when controlling the at least part of the HVAC system of the building;

a controller coupled to the touch screen display and the memory;
the controller configured to provide access to a setup menu for entering a plurality of equipment setup parameter values each corresponding to one of the plurality of equipment setup parameters;
the controller further configured to provide access to a ventilation review menu in which the ventilation related equipment setup parameters are viewable in a read-only mode in which each of the ventilation related equipment setup parameters are displayable on the touch screen display but cannot be edited without exiting the ventilation review menu and accessing the setup menu, and where the non-ventilation related equipment setup parameters are not displayed; and
the controller further configured to control at least a portion of the HVAC system based at least in part on the plurality of equipment setup parameters.

12. The HVAC controller of claim 11 , wherein the controller is further configured to display an advanced menu, and the ventilation review menu is an option on the advanced menu.

13. The HVAC controller of claim 12 , wherein the setup menu is also an option on the advanced menu.

14. The HVAC controller of claim 11 , wherein the controller is configured to:
display a home screen including a menu button;
allow a user to access an advanced menu by touching the menu button for at least a predetermined period of time; and
allow a user to select the ventilation review menu via the advanced menu and to scroll through a plurality of screens within the ventilation review menu.

15. The HVAC controller of claim 11 , wherein the ventilation related equipment setup parameters comprise one or more of a run time percentage, a ventilation type, a ventilation rate, a number of bedrooms, building square footage and ventilation priority type.

16. A method of confirming that a building's ventilation parameters meet building code requirements of a building, the building including an HVAC system that includes HVAC equipment including ventilation equipment, and also includes an HVAC controller for controlling at least part
