Electronic Temperature Control (Domestic)
Operation
The temperature control is factory set to stop the power to the kettle when the thermocouple reaches
setpoint. This is also the ideal point to dump the popped corn out of the kettle. On the first start-up, this is
the ideal time to load the corn and oil. Therefore, if the Kettle Heat Switch is turned ON and the buzzer is
sounding, one of the following actions should be taken:
Load the corn and oil or
Dump the popped corn from the kettle or
Turn OFF the Kettle Heat Switch if you are finished popping corn.
Adjustment of Electronic Control
This unit has an electronic kettle control with 2 thermocouples (TC), one for control and one for limit.
There are no mechanical thermostats in this kettle.
There are (4) factory adjustments on the control:
1.
Control Setpoint Temperature – This is factory set, DO NOT adjust.
2.
Signal to Dump – If you want the signal to dump to be a little sooner or later, you can
adjust the Kettle Dump potentiometer (see image below). Turn clockwise (CW) to
signal sooner, counterclockwise (CCW) to signal later.
3.
The patented Overshoot circuit is tuned for the kettle, DO NOT adjust this potentiometer.
4.
The Audible Signal to Dump has three options; full volume, half volume, no sound (yellow
light only). Adjustments are made by jumper positions (see image below). The unit is
shipped with full volume.
