Chapter 3 – Operation
Introduction
The Front Panel Switches control power to the temperature controller and all chamber functions.
The Limit Controller is a protection device. It turns the chamber OFF and sounds an alarm if the
workspace temperature exceeds either a high temperature or low temperature limit set point.
The Temperature Controller controls the temperature of the chamber. The Temperature
Controller automatically turns the refrigeration system on or off as required based on the
deviation from temperature set point.
Refer to the separate F4 or F4T Temperature Controller manual for details on how to use
the Temperature Controller.
