Troubleshooting Mysa AC code set download errors
Audience: External (Mysa Customers)
If the Mysa app shows an error while downloading a remote code set for your Mysa for Mini-Splits / Mysa AC, the download may be taking longer than expected because of a weak or slow internet connection. Some code sets are larger and can take extra time to download.
What to try
- Retry the code set download. Wait a moment, then try downloading the code set again from the Mysa app.
- Move closer to your router. If you are setting up Mysa in an area with weak Wi-Fi, temporarily move your phone and Mysa closer to the router while completing setup or code selection.
- Check your internet connection. Make sure your phone has a stable internet connection and that your Wi-Fi network is working normally.
- Keep the app open while the download finishes. Avoid switching apps or locking your phone during the download.
- Try again after restarting the app. Force close and reopen the Mysa app, then repeat the code set download.
If it still does not work
If the code set continues to fail after retrying near the router, contact Mysa Support. Include the product type, the step where the error appears, the code set or brand you are trying to use if known, and a screenshot of the error message with any personal information hidden.
