Hi All!
I've recently moved house and removed my setup (which worked great) from a combi boiler set up and trying to install on a conventional boiler but only for CH at present! My initial install consisted of removing the old thermostat and wiring in the BDR91. All was good, everything works goes on and off with demand etc. Over the next 2 and half month I managed to burn nearly 1000 litres of oil in a house that wasn't particularly hot and a thermostat that was only set on 20-21!
At this point I figured something was wrong so investigated why there was so much demand. I found various draughts around windows and doors etc so removed Hr92 from these rooms until repaired. I think I'm now in a relatively draught free house and just using the evotouch as the only thermostat for the whole system. It's placed in the front room and the rest of the house seems stable. I've now started to notice irratic behaviour such as the br91 turning on when the room temp is 2 degrees above set point. If I cancel it it won't come back on until it should do. Reading through the forum looking for an answer I've now seem that I need to remove the motorized zone valve that controls the heating? Do I really need to do this if everything is working? Could someone explain the reason why? I'm no plumber but fairly handy but just can't get my head around this!
I guess overall I'm losing a bit of faith in a system that worked perfectly for me in a previous set up so I'm thinking I've gone wrong somewhere. If I've burnt so much oil why does my house feel chilly... Surely I should be roasting. I'm reluctant to refit the Hr92 in case it makes it worse again. I'm considering using a Dt4r instead of the evotouch to rule out issues with that.
Any helps appreciated. I don't want to give up on it because I know it's worth. My plumber doesn't like the system so isn't the greatest of help!!
