It may not help you at the moment with a changed password, but you can purchase a Carrier Service tool and access anything you need to via the Carrier network or the connector on the front of the Comfort link. No password is required when you are using the tool. Its somewhere in the $500.00 range. You should search the carrier data base for the PDF file for the comfort link and save it. I know of no person that can memorize all of the alarm codes on that control. Good luck.
