(cont.)


826-2086 (115/230V):
These boards are used in HD fryers equipped with Thermatron control
systems.



Thermatron systems incorporate a temperature probe, a potentiometer, and a temperature control
circuit board. This system is more accurate and reliable than a standard thermostat. The temperature
probe measures oil temperature via resistance (ohms); as oil temperature rises, resistance decreases.
The potentiometer sets the oil temperature via resistance (ohms). The temperature control circuit
board compares the resistance from the probe and potentiometer and cycles the burner on and off as
necessary.
