producing electrical pulses that are transmitted to the display. The display

converts these pulses into a read-out of minutes and seconds. The

temperature portion of the Time/Temp Display uses a Thermistor Probe to

sense oven temperature. The thermistor outputs a resistance proportional

to the oven temperature. This resistance is then converted by the display

into a temperature reading.

AUTOMATIC COOL DOWN

permitting the oven fans to run for approximately 20 minutes after the oven

is shut off, to cool the oven. The Time Delay Relay will keep the coil of

Relay closed maintaining operation of the Main Fan Motor and cooling

fans.
