Our very popular book is an excellent reference for you to use on central heating wiring.
Central Heating Wiring & Controls Book 3
The aim of this book is to make wiring easier and more rewarding. It has been designed to help you carry out installations and fault finding on control circuits by giving you all the information you need in a clear and logical manner.
We have worked closely with the technical departments to take their existing wiring diagrams and schematics and turn them into full colour illustrations which are much easier to understand and use.
The most common control circuits in use in the UK are the three port (Mid Position) and two and three port zone circuits. This book therefore contains a greater number of diagrams for those circuits.
For many years electricians and heating engineers have commented that wiring heating controls is a difficult subject to learn, (this book is easy to follow).
They want to be able to wire and test these circuits with confidence but the existing diagrams are not always easy to follow.
This book is for all levels from basic to advanced easy to follow.
