Most "Heating Engineers" are at best technicians NOT Engineers, despite what BG and others state. If Honeywell made the installation more simple then anyone, technician or public could install Evohome and publicise how good it can be.
Have you completed the free online training course we offer:

I work for Resideo. However, any views expressed are mine and not those my employer.
I found the online training really easy, and perhaps a bit superficial, and wondered whether that's why the specialist who installed my system was so awful (BDRs installed next to each other, s-plan with one of the BDRs bound as a boiler relay, etc. etc.)
These are common problems - they come up time and time again here - but the online training didn’t really emphasise these problem areas. Or rather, it didn’t when I did it, perhaps the content has been updated now?
I was about to make the same comment! I do not see installing Evohome as rocket science. I am not from an electrical, plumbing, heating or engineering background. I did the course after I had installed my system and cannot remember learning anything more than I already knew or is in the manual, if you take time to understand it! Years ago, Richard from The Evohome Shop, produced in these pages far more helpful guidance than the course or the manual. I have already mentioned I contacted a Honeywell authorised person. A very nice chap, knew central heating and plumbing, but nothing about Evohome!
The reason I called him was because I thought I had not done it right. It’s when I realised you install the HW relay first! He did not know that. Also I thought there were issues with the wiring but there weren’t. I found out later that why I had problems was the builder of my house for some reason had two live feeds for the central heating - one from a fuse marked “Central Heating” and the other from a fuse marked “Security System”!
This “authorised professionals” bit sounds more like an attempt to show the customer is important, not something that has generally fallen within Honeywell’s remit in the past and from other’s experiences with these authorised bods it would seem no check is made to ensure they are up to the job.
Thank goodness that within these pages there are some who know their stuff and have been really helpful to us all, we are grateful. It does not seem that Honeywell take on board and rectify the bugs and quirks they uncover.
