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
