## What is Wiring & Controls?

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.

### 5/5 — Excellent

*2021-03-28, version 1.5*

Thankyou , George.

### 5/5 — Every gas engineers bible!!

*2019-03-27, version 1.5*

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.

### 1/5 — Worthless App

*2018-05-26*

This app is only of use if you are a HVAC tech, and then only if you are using a very selective type of controls.  Total waste o my money!

### 5/5 — Excellent

*2016-04-24, version 1.0*

Clear diagrams 
Excellent guide to use Easy and accurate
