  3. Press the Test button

  4. Verify the trip indicator illuminates

  5. Wait 5–10 minutes to confirm the floor heater cools

Tip Set a monthly reminder to test your GFCI. Regular testing ensures the safety circuit is functioning properly.

Manual Operation Without Wi-Fi

If your Mysa loses Wi-Fi connection, you can still control the temperature manually using the up and down arrows on the front of the thermostat.
