I do understand the TPI can result in the boiler only firing for a short time, but in my case it sometimes comes on for such a short time it doesn't even ignite!
If you have a system with a boiler relay then you can adjust the parameters so that this doesn't happen, but if you've got an S plan setup (which doesn't have a boiler relay) those parameters aren't used.
My current thinking is that that's possibly a mistake (certainly a shortcoming), and that the system could be improved if logic was added such that the minimum on and cycle timings were available in an S Plan setup.
Anyway, I have the experts coming to take a look a look on Friday, so I'll know more after that.
DESPITE that little niggle, I still think Evohome is great. My house feels much more comfortable than it did with the old heating controls.
