If you see a numeric error code (i.e. Error ###.## or Err ###.##), please contact your local HVAC dealer for service.
If you do not currently have a dealer, or need your dealer's contact information, please refer to our article Finding Dealer Information.
It is highly recommended that you opt into American Standard® Diagnostics if you have not done so already. This will allow your dealer to see real-time information from your system to aid in diagnosis and repair. Additionally, this gives you the option to grant your dealer limited remote access to your smart thermostat to view, edit, and adjust your settings if necessary, avoiding any unnecessary service appointments.
For more information on Diagnostics and Dealer Remote Access, please refer to:
