AUTOMATICTIC ELECTRONIC TIMER (Solid State)

The electronic timer featured in certain models provides full automatic timing of bake/roast or self-clean oven operation by means of two relay-opened S.P.S.T. switches which are normally open, contact 11-12 and 13-14. 120 VAC power is connected to terminals 1 and 2. The numeric value of the 4-digit display can be increased by clockwise rotation of the "Time Set" knob and decreased by counter- clockwise rotation. All knobs are removable by pulling straight out.

Indicator arrows (LED) are aligned over each of the four (4) push button function knobs and associated with that func- tion. Each indicator arrow is lighted during operation of that function and goes off at the end of that function. With the exception of the self-clean button, pressing in any one of the three buttons on the left lights the respective indicator arrow which then allows only three (3) or four (4) seconds to set the time on the display, then the display reverts to time-of-day if nothing is entered. To set time-of-day in the display, simultaneously press in any two of the three buttons on the left and enter the digits with the time set knob. The time-of-day clock has no AM and PM indicator.

SELF-CLEAN TIMER OPERATION

The self-clean button on the right, when pressed, immedi- ately enters three (3) hours in the display and both relay switches close. On the left side of the display a small oven- on symbol will appear along with the letter "C" (cleaning). If the other range controls are set for clean, the oven will start immediately. The self-clean time, three (3) hours, can be increased to a maximum of four (4) hours or reduced to less than three (3) hours with a "time set" knob. At the end of the clean operation the display returns to Time-Of-Day, the switches open, and shut off the oven. For delayed start, set the "Stop" button for desired stop time. The timer will calculate the required start time and start the oven accord- ingly.

BAKE-ROAST TIMER OPERATION

Baking or roasting in automatic time cook mode provides the option of cooking for a specific time period starting immediately or delaying the start to a later time. For timed cook, starting immediately, push in the bake button and enter the cooking time period. The relay switches will close, the indicator arrow will be lit to indicate that the oven is on (thermostat must be set to a temperature setting and selector in timed bake position). For delayed time cook, it is necessary to set the "Stop Time" button for the time desired for the cooking to be completed, then set the length of cooking time. The oven and clock timer will start the required period of time before the stop time to complete the cooking. As an example, assume it is 1:00 p.m., the food to be baked or roasted will require two (2) hours and it is desired to have it cooked and ready to serve at 5:00 p.m. The procedure would be to set the thermostat to the desired temperature and the selector to timed bake. Then push in the "Stop Time" knob and set the display for 5:00. Next, push in the "Bake Hours" knob and set the time for cooking

-two (2) hours. The timer will automatically calculate the start time 3:00 p.m., and turn on the oven. When program- ming the clock for this function the "Bake Hours" knob can be pushed first and two (2) hours entered. Then the 5:00 p.m. "Stop Time" programmed. The timer will still calcu- late the start time and operate the oven. When the oven is programmed either for timed cook or for the self-clean the indicator arrows will flash slowly to indicate a program is in operation. When a program is in operation, the time of day cannot be changed, only the program time can be advanced or reduced. If it is desired to stop a program before completion, turn the thermostat and selector to OFF. This will stop oven operation but not the clock timer program operation. This may be allowed to continue or may be stopped by pressing the respective operational
