1 Introduction to the Controller and Manual
1.1 Using This Manual
This manual aims to explain how to set up and operate the 301 controller; it must be read in
conjunction with the product main manual.
Due to the complex nature of furnace or oven control the use of technical terms throughout
this manual is unavoidable. Explanations of these terms can be found in the ‘Glossary of
Terms’ at the back of this manual.
1.2 PID Control
The 301 controller uses PID (Proportional Integral Derivative) temperature control. This
type of control uses a complex mathematical control system to adjust the power being sent
to the elements and hold the furnace or oven at the desired temperature.
1.3 Key Stroke Diagrams
Throughout this manual, key stoke diagrams are used to quickly describe the key presses
required on the controller to alter the desired value.
Examples of key press sequences:
