Working from a comprehensive wiring diagram which I produced son no 2 wired the Megaflow wiring centre whilst son no 1 whose house it is did all the geeky bits setting up and binding all of the radiator controllers, the BDR relays and cylinder temperature insertion sensor.

When the system finally went live everything worked as planned and we are currently evaluating the set points for the various rooms.

We are a savvy DIY family and the installation, wiring and commissioning the system was in honesty easy.

I would commend Evohome as ideal for anyone with the capabilities to make it work. On reflection I'm surprised how easy it was and how trouble free. Everything just worked.

Thanks for all the helpful advice and help from this forum during the planning phase.
