Does the Sentry Xpress have an error message for a temperature drop during a hold?

The 3-key Sentry Xpress Orton controller does not have an error message for a temperature drop during a hold. This is because the controller is used on enameling and bead-making kilns where the door is opened frequently during holds, causing a temperature drop. The 12-key Sentry Orton controller has an LTDE low-temperature alarm, however.
