If you are receiving an H2 error, this is caused by Mysa not registering a heater load connected.
Please review the connection between the Mysa Load and the heater load, as this connection may have come loose. Additionally, we recommend ensuring that the correct wire has been run to Mysa.
If you are receiving, an I3 error, this would indicate the the sensor wire is not connected to your Mysa In-Floor thermostat. Please check this connection and ensure this is secure.
If Mysa for in-floor is displaying any code other than the above please contact our support team and we will be sure to get this corrected.
