HIGH EFFICIENCY DECATHLON SERIES GAS FRYERS

Interface Boards (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.
