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.

Worthless App
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!
