With special permission from Danfoss and Honeywell, we took their wiring diagrams and turned them into fantastic coloured wiring diagrams which are much easier to follow. We've been using these diagrams on our training course for over two years and everyone agrees that they're essential for wiring up controls on two and three port installations.
