III. Resetting the Controller to Original Factory Settings
J-KEM manufactures the most technically advanced temperature controller available and should give you consistently flawless
control. If you have difficulty with your controller, a good place to start to correct the problem is by loading the original
factory settings as detailed in the procedure below. If you still have difficulty with your controller, our Engineering
Department will help you resolve the problem. Before beginning this procedure, plug a thermocouple into the channel being
reset.
Procedure to Reset the Controller to Original Factory Settings
