Ok we will try it again....

The relay is not part of the controller. It may be on same panel as controller but not part of controller electronics. It (relay) is only connected to the controller.

IF the relay is not part of controller, the controller can not issue a controller error for relay failure because controller does not know relay may have failed.

Generally a controller is only capable of sensing if thermocouple has gone open circuit or not connected and then it may issue a error code ...
