Abstract

A controller for controlling an environmental condition of a building via building equipment includes a user interface configured to present information to a user, an air quality sensor configured to sense indoor air quality conditions, a communications interface configured to communicate with a server system and receive outdoor air quality data from the server system, and a processing circuit. The processing circuit is configured to generate indoor air quality data based on the sensed indoor air quality data conditions sensed by the air quality sensor, receive, via the communications interface, the outdoor air quality data from the server system, and generate one or more interfaces indicating the indoor air quality conditions and the outdoor air quality conditions based on the indoor air quality data and the outdoor air quality data and cause the user interface to display the one or more interfaces.

First claim

What is claimed is:

1. A controller for controlling an environmental condition of a building, the controller comprising:
a user interface configured to present information to a user and receive input from the user; and
a processing circuit configured to:
operate a plurality of system components to perform a plurality of system tests to determine whether the controller is installed correctly;
receive, via the user interface, a plurality of indications of proper installation or improper installation from the user, wherein each of the plurality of system tests is associated with one of the plurality of indications;
generate a system test summary page based on each of the plurality of indications; and
cause the user interface to display the system test summary page.

2. The controller of claim 1 , wherein the controller further comprises a plurality of wiring terminals and one or more detection circuits for the plurality of wiring terminals configured to determine whether a wire is connected to each of the plurality of wiring terminals;
wherein the processing circuit is communicably coupled to the one or more detection circuits;
wherein the processing circuit is configured to:
receive an indication of whether the wire is connected to each of the plurality of wiring terminals from the one or more detection circuits;
generate a wiring user interface based on the indication of whether the wire is connected to each of the plurality of wiring terminals, wherein the wiring user interface comprises an indication of each of the plurality of wiring terminals and an indication of which of the plurality of wiring terminals the wire is connected to; and
cause the user interface to display the wiring user interface.

3. The controller of claim 2 , wherein the processing circuit is configured to:
receive, via the user interface, a first terminal override command in response to the user taping a first indication of a first wiring terminal of the wiring user interface;
update a wiring interface to display an indication that the wire is connected to the first wiring terminal based on the first terminal override command and in response to determining that the wire is not connected to the first wiring terminal;
update the wiring interface to include an override indication indicating that the first wiring terminal has been overridden; and
cause the user interface to display an updated wiring interface.

4. The controller of claim 2 , wherein the processing circuit is configured to:
receive, via the user interface, a first terminal override command in response to the user taping a first indication of a first wiring terminal of the wiring user interface;
update a wiring interface to not display the indication that the wire is connected to the first wiring terminal based on the first terminal override command and in response to determining that the wire is connected to the first wiring terminal;
update the wiring interface to comprise an override indication indicating that the first wiring terminal has been overridden; and
cause the user interface to display an updated wiring interface.

5. The controller of claim 2 , wherein the processing circuit is configured to operate the plurality of system components to perform the plurality of system tests to determine whether the controller is installed correctly by causing a fan to run in response to determining that the wire is connected to a fan terminal;
wherein the processing circuit is configured to generate a fan operation interface comprising a question regarding whether the fan is circulating air and cause the user interface to display the fan operation interface; and
wherein receiving, via the user interface, the plurality of indications of proper installation or improper installation from the user comprises receiving, via the fan operation interface, an indication regarding whether the fan is circulating air.

6. The controller of claim 2 , wherein the plurality of system tests comprises a heating test, wherein the processing circuit is configured to perform the heating test by:
causing a heat pump to heat the building in response to determining that wires for the heat pump are connected to the plurality of wiring terminals;
generating a heating test question interface comprising a question regarding whether hot air is exiting a vent of the building and causing the user interface to display the heating test question interface;
receiving, via the user interface, an indication regarding whether the hot air is exiting the vent of the building;
generating a reversing valve polarity question in response to receiving the indication indicating the hot air is not exiting the vent of the building, wherein the reversing valve polarity question asks the user whether cold air is exiting the vent of the building and causing the user interface to display the reversing valve polarity question;
switching a polarity of a reversing valve command in response to receiving, via the user interface, an indication that cold is exiting the vent of the building; and
performing the heating test a second time with the reversing valve command.

7. The controller of claim 2 , wherein the plurality of system tests comprises a cooling test, wherein the processing circuit is configured to perform the cooling test by:
causing an air conditioner to cool the building in response to determining that wires for the air conditioner are connected to the plurality of wiring terminals;
generating a cooling test question interface comprising a question regarding whether cold air is exiting a vent of the building and causing the user interface to display the cooling test question interface;
receiving, via the user interface, an indication regarding whether the cold air is exiting the vent of the building;
generating a reversing valve polarity question in response to receiving the indication indicating that the cold air is not exiting the vent of the building, wherein the reversing valve polarity question asks the user whether hot air is exiting the vent of the building and causing the user interface to display the reversing valve polarity question;
switching a polarity of a reversing valve command in response to receiving, via the user interface, an indication that hot is exiting the vent of the building; and

performing the cooling test a second time with the reversing valve command.
