Flow/Return Thermistor Fault.

Had this for the second time now. Pressing restart gets it working.

I have contacted the installer as well but im wondering if it could be something simple. The installer asked if i had a bypass radiator and was it fully open. Which i dont have as that would defeat the point of Evohome, i do have an auto bypass valve though. Could it just require opening a bit more.
This issue only ever happens when the system first comes on, so either first thing in the morning or when I get home from work.

Well, your installer, who knows more about the role system than us has made a suggestion, but you know better.

What chance do you think we have?

I'm wondering from experience this fault occurs where a bypass isn't working or such.
If it is I might be able to change some settings in evohome or the trvs that keeps a couple open a little bit. Or just give the auto bypass a quarter turn open.
You know rather than book a day off work for them to do the same thing.
