Occurs when the HEAT RATE is set to COOL but the TEMP of that stage is
higher than the TEMP of the prior stage (should be heating). This will occur
when a program is already running and a parameter was edited in process.
Occurs when the temperature on the display is outside the allowable range
at the time the user pressed the ENTER / REVIEW keys simultaneously to set
the Infinity calibration temperature to 1500°F. If this occurs and is not an
operator error, it indicates that there is a problem with the thermocouple or
the PC board. Press ENTER / REVIEW to turn off the error indication and
continue with the program. Press START / STOP to end the program.
Occurs when PC board hardware malfunctions.
Occurs if the thermocouple is open or the connecting wire(s) are broken or
disconnected from the terminal board.

plates for 5 minutes. This error will also occur if a program is running
and the door is kept open for more than 5 minutes or the triac or the
Main PC board developed a problem during a burnout process.
Occurs when the temperature has exceeded 2015°F (1102°C) for 1
minute if the highest temperature programmed was less than 2000°F
(1093°C). This also occurs when the temperature has exceeded
2050°F (1121°C) for 1 minute if the highest temperature programmed
was 2000°F (1093°C) or higher.
Occurs when the HEAT RATE in STAGE 2, 3 or 4 is set to “COOL” but
the corresponding TEMP is entered to heat to a higher temperature
