Troubleshooting Features
Temperature Controller Auto Tune: Occasionally it may be necessary to perform an auto tune procedure on the temperature controller so that it can more accurately control the temperature in the oven. Follow the steps to perform the auto tune function:
Open the door on the main control panel, then energize the panel. Go to the touch screen and start the oven. Allow the burner to ignite and the temperature to come up to within 30 degrees of the set point. Locate the temperature controller in the main control panel. Press and hold the P button on the controller.
The controller will begin to flash “tUNE” and “no” at the bottom.
Tap the up arrow to change the “no” to “yes”.
Tap the P button several times until the display reads “End”.
A small “AT” indicator will begin to flash under the “OUT2” indicator. The oven will now overshoot and undershoot the temperature set point 4 times so that the controller can learn how long it takes the temperature to rebound. After the process is complete, the “AT” will stop flashing, and the oven should hold the temperature within a few degrees of the desired set point.
