This device appears to only use the MAC ID. I had similar issues.
Sorry, there was a problem. Please try again later.Hi pckeys, the T5+ only has a MAC ID. The T5+ is registered through the Honeywell Home app, and a CRC is not required to register the thermostat. If you have additional questions, feel free to contact our support at 1-800-633-3991
