Step 8 Operate the Controller Summary of Key Functions in Operation Mode Key Function A Menu 1 B Menu 2 C Menu 3 D Menu 4 E Menu 5 F Menu 6 Start-up Apply power to the oven. [`idle] will appear on the display. If the Real Time Clock Display option is installed and [setUp] / [time] is programmed, the time of day will appear on the display.
The heat output indicator light - G, just below the display- will light up whenever the controller is calling for heat. When the oven is at operating temperature (above the relative set point minus the ready band) [ready] will appear on the display and the menu key indicator light will flash rapidly. You are now ready to cook with the active menu. • If the oven is at operating temperature, the display goes directly to [ready] without indicating preheat or temperature.
With Sound set to 0, the controller automatically switches to idle in which the controller does not maintain temperature and does not run time. [`idle] or time of day will appear on the display. The menu key indicator light will be off. With Sound set to 1, 2, or 3, [``end] will appear on the display and an audible tone will be emitted. The menu key indicator light will flash rapidly. You can acknowledge the tone by pressing the active menu key or it will time out in 1 to 20 seconds and go into idle.
4. Once the controller goes into idle, the menu key indicator light and the heat outputs will switch off. The controller will not regulate to any temperature. 5. To repeat cooking, repeat steps 1 through 2 or 3. Pause a Menu While cooking, you can pause cooking time by pressing the active menu key once. The menu key indicator light will flash rapidly. [PAUSE] will appear on the display. Countdown time will resume when you press the active menu key again.
Errors The controller will alert you to errors if they occur. Errors are critical problems that shut down the unit. If an error occurs, an error message will appear on the display. You should switch off the power and call for service. See the Appendix in the Hardware & Software Setup Guide for a Troubleshooting Chart and a summary of errors.
