NOTE:	The Conveyor Control uses a sensor and magnet, mounted on the
	Conveyor Motor that senses when the motor is not turning. If the motor is
	not turning, the Time/Temp Display will show “—:— “ in the window.
	The temperature portion of the display uses a Thermistor Probe to sense
	oven temperature. The Thermistor outputs a resistance proportional to
	oven temperature. This resistance is then converted by the Display into a
	temperature reading.
	OR:
	The temperature potion of the display uses a “J” type thermocouple to
	measure oven temperature. The thermocouple generates D.C. millivolts
	proportional to oven temperature. This millivolt reading is then converted
	by the display into a temperature reading.
