# Set Thresholds

CO₂ Monitor tile background colour and emoticon correspond to CO₂ values thresholds set in **PUBLIC TILES** menu:

<div data-with-frame="true"><figure><img src="/files/5P5yFT9W1OwMrPD2ew6F" alt=""><figcaption></figcaption></figure></div>

When the measured CO₂ level is in the *Good* zone, tile has green background, in the *Average* - yellow, and in the *Unhealthy* - red.

The default values are visible on the screen. You can change CO₂ thresholds anytime, by pressing on CO₂ Thresholds button, which redirects you to settings. When you click on the button, you will get the following message:

<div data-with-frame="true"><figure><img src="/files/e9iaPS7uD0o0FwPtPNnt" alt=""><figcaption></figcaption></figure></div>

If you have not finished creating the tile yet, then we suggest you press Keep editing, create your tile, and then go to Settings manually, but if you are all set, then press Go to settings. After pressing the button, you will see the following screen, where you can set up your own thresholds for CO₂ levels:

<div data-with-frame="true"><figure><img src="/files/0CPlJ1Ti4yegnveIJzSz" alt=""><figcaption></figcaption></figure></div>

Don't forget to save your changes by clicking on **SAVE** button.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.aranet.com/aranet-cloud-page/aranet-cloud-landing-page/user-interface-and-core-features/public-tiles/set-thresholds.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
