Abstract

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.

Claims

a memory storing an algorithm that at least partially controls the one or more components of the HVAC system;

a controller operating the algorithm that at least partially controls the one or more components of the HVAC system; and

the controller configured to display on a display a first parameter setup screen where upon a user can set one or more first parameter values, and subsequently display on the display a second parameter setup screen where upon a user can set one or more second parameter values, the second parameter setup screen having one or more parameters that are or are not displayed depending on the one or more of the first parameter values set via the first parameter setup screen, and wherein the algorithm uses the one or more first parameter values and the one or more second parameter values to at least partially control the one or more components of the HVAC system.

2. The HVAC controller of claim 1, wherein the first parameter setup screen includes a number of heating stages parameter, where upon a user can set the number of heating stages of the HVAC system, and the second parameter setup screen includes a number of cycles per hour for each of the number heating stages set via the first parameter setup screen.

3. The HVAC controller of claim 1, wherein the first parameter setup screen includes a number of cooling stages parameter, where upon a user can set the number of cooling stages of the HVAC system, and the second parameter setup screen includes a number of cycles per hour for each of the number cooling stages set via the first parameter setup screen.

4. An HVAC controller configured to control at least part of an installed HVAC system, wherein the installed HVAC system has an installed subset of one or more HVAC components selected from a set of possible HVAC components, the HVAC controller comprising:

a memory storing an algorithm referencing a plurality of setup parameters that setup the algorithm to at least partially control the installed subset of one or more HVAC components of the HVAC system;

a controller in communication with and programmed to at least partially control one or more HVAC components of the installed subset of HVAC components, the controller operating in accordance with the algorithm stored in the memory; and

the controller initiates two or more of the plurality of setup parameters to be displayed on a single screen and accepts changes to the two or more of the plurality of setup parameters, wherein the two or more of the plurality of setup parameters that are displayed on the single screen are part of a common setup category.

5. The HVAC controller of claim 4, wherein the common setup category includes a number of stages of the HVAC system.
