DECATHLON SERIES GAS FRYERS (CE)
CHAPTER 5: THERMATRON OPERATION
5-1
5.1 Operating Fryers with Thermatron Controllers
Many Decathlon fryers use a solid-state
temperature controller, or Thermatron
®
controller
instead of a computer or basic thermostat. A
Thermatron
system incorporates a temperature-
control circuit board, a potentiometer, and a
temperature probe. This system is more accurate
and more reliable than a standard thermostat, and
less expensive than a computer controller.
Various switch options are available on
Decathlon frying systems. Two typical
configurations on current production systems are
illustrated below (switch locations will vary from
model to model).

Fryer Power Switch: controls power to
each individual fryer, both in Thermatron or
back-up mode.
Boil-Out Switch: operates only in "Thermatron" mode. When
"ON", this switch bypasses the Thermatron melt-cycle and
allows the water temperature to reach 196°F.
Main Power Switch (optional): connects/disconnects primary
power; double-lighted with center position "OFF". This switch
controls two Thermatron controllers /Compu-Fry computers and/or
two back-up thermostats (optional).
High-Limit Reset Switch: located under
each individual control panel. This
switch must be manually reset if fryer
exceeds high-limit setpoint.
Filter Reset Switch [7 Amp (115VAC)
or 5 Amp (230VAC) Circuit Breaker]: this
switch is inline between the filter pump
and incoming line voltage. Ensure
power is "OFF" before resetting or
replacing.
