The Fault Finding & Multimeters Course is designed for installers who want to improve fault finding, servicing and repairs for their customers, or maybe change from installing and move into. In our shop you can pay for places on the one day training course, buy DVDs, books and tools. Mr Combi has produced two training DVDs to help you get the most out of your multimeter. Our wiring course will help you understand the problems of wiring boilers and zone valves. Danfoss & Honeywell have given us special permission to provide you with technical support not normally.
