Book of Wiring

Our brand new Book of Wiring is now complete and on sale!

For many years electricians and heating engineers have commented that wiring heating controls is a difficult subject to learn. They want to be able to wire up and test these circuits with confidence but the existing diagrams are not always easy to follow.

Following the example of the London Tube Map, we’ve developed a fantastic new set of coloured wiring diagrams for Danfoss and Honeywell controls.

In our Book of Wiring you’ll find a vast array of information and diagrams, including:

  • Four part Electrical Safety Tests
  • Danfoss 2 and 3 port valves
  • Honeywell S, Y, C & W Plans
  • Frost Protection
  • Schematics
  • Fault Finding Charts
  • Boiler wiring
  • Programmer wiring
  • Checking components
