This module may be installed on the EC0X chamber and allows the user to set an upper and lower temperature limit trip point via two potentiometers located on the module. It features an LCD to display the upper and lower temperature limit trip point as well as the current air temperature inside the chamber. It also provides GFI (Ground Fault Interrupt) protection.
