3 Apps in This Bundle



Our Training Bundle comes with three great apps to help you improve your skills and become a master of your trade.

The Fault Finding, Testing & Multimeters app contains 21 chapters of guidance and tips covering everything you need to know about fault finding and testing on combi boilers.

Our brand new Wiring & Controls app comes with 19 chapters of excellent advice covering two and three-port heating systems. We cover the differences between the systems, how to wire them up, testing, fault finding and more.

The Wiring & Controls - Diagrams app includes all the main two and three-port diagrams you'll need on the job. No longer do you need to strain your eyes and brain trying to wire up a heating system using a small, black and white, diagram; with our app you can view the diagrams in full colour, full screen and even pinch and zoom!

Save money by getting all three apps for one discounted price.
