DECATHLON SERIES GAS FRYERS

Interface Boards
The interface board provides a link between the controller/computer and the fryer’s individual
components without requiring excessive wiring, and allows the controller to execute commands
from one central point. Two types of interface boards may be used in Decathlon Series gas fryers;
the type used depends on the fryer configuration.
In units configured for Thermatron, P/N 826-2086 (115/230V) is used; in units configured for
Compu-Fry computers, P/N 106-6710 is used.
IFB 826-2086 (115/230V): These boards are used in Decathlon 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.
