Troubleshooting; Zone Diagnostics - Welbilt Frymaster UHCTHD Service Manual

The software shall track the state of each thermocouple and the state of the thermocouple reading compared
to the set point. If the software finds an error, it will begin to time it. When the timer reaches 15 minutes, an
error code(s) will display (flash) on the screen. This shall continue indefinitely until the zone is +/- 5 degrees of
the set point or the unit is power cycled off and the 15 minute time starts again. If an error is still present, it
will be displayed until corrected.
