Hi

I have a baxi Bermuda back boiler, honeywell thermostat and timer too. After resetting the time two days ago the heating now comes on as well as the hot water even though switched off on the timer.

All radiators come on full, the stat is down as low as it goes, any ideas on a fix or steps to avoid problem? House is like a sauna!

Thanks

welcome to the forum alex, I presume you have set the timer wrong, post a picture of the timer

could be your three way or two way valve(whichever you have) is not working correctly and letting by. could be coincidence that the timer was reset at the same time.

Hi thanks for the replies - Its not the timer being set wrong - I've reset it many times over the last 6 years here and have had this problem intermittently. I do think there is a fault with the timer as often changes to a random time and settings, like 2:80!

So changing the 3 way valve and/or the timer- DIY job or professional needed?

professional required, find the valve and check if the opposite side to the connection going into ur cylinder is getting hot, if so y plan needs changing
