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.
• Colour diagrams for Danfoss and Honeywell systems
• 2 and 3 port systems
• Fully Wired diagrams - Shows every wire in the control circuit
• Live Wire diagrams - The earth and neutral wire have been removed for clarity
• Schematic diagrams - A simplified version of the circuit
• Stats diagrams - Only the thermostat circuit is shown
• Danfoss and Honeywell wiring centre schematics
• Frost protection diagrams
• Fault finding charts for Danfoss systems
We've added a diagram for Danfoss 3 x Two-Port systems

Every gas engineers bible!!
I use this app every time there’s a wiring problem. Simple to use and always gets me out of trouble.
Just one request...please can you add a wiring diagram for “2 zones on a combi boiler”.
I came across a vaillant combi that had 2 zones, heating & underfloor heating. This would make this app a step above the rest.
Excellent guide to use Easy and accurate
