DECATHLON SERIES GAS FRYERS (CE)CHAPTER 5: THERMATRON OPERATION5-15.1 Operating Fryers with Thermatron ControllersMany Decathlon fryers use a solid-statetemperature controller, or Thermatron® controllerinstead of a computer or basic thermostat.

This system is more accurateand more reliable than a standard thermostat, andless expensive than a computer controller.Various switch options are available onDecathlon frying systems.
