Chapter 3 – Operation
Introduction
The Front Panel Switches control power to the temperature controller and all chamber functions.
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.
Summary of Chamber Operation
1. Turn the POWER Switch ON.
2. Enter the desired temperature set point on the Temperature Controller.
3. Load your test sample in the chamber.
4. Turn the TEMP Switch ON. Alternatively, turn the TEMP Switch to the EVENT 1 position
and turn EVENT 1 on the F4 controller or the Power button on the F4T controller ON.
Front Panel Switches
POWER Switch
The POWER Switch controls power to the entire chamber. The POWER Switch illuminates
when it is ON.
TEMP Switch – ON Mode
The TEMP Switch enables all chamber functions. When the TEMP Switch is OFF and the Power
Switch is ON, only the Temperature Controller and Limit Controller are operational. When both
the TEMP and POWER Switches are ON, the chamber’s temperature conditioning system will
function to maintain the temperature set point. The TEMP Switch does not illuminate.
TEMP Switch – EVENT 1 Mode
When the TEMP Switch is in the EVENT 1 position, you can enable and disable all chamber
functions through Event 1 (Digital Output 1) of the F4 Temperature Controller or the Power
button on the F4T Temperature Controller.
