Iíve had my Evohome system for a couple of years now and think itís great. One thing that is bugging me more and more (canít work out if it has suddenly got worse or Iím just getting older and grumpier!) but the TRV in our bedroom (might be the others do it too but the bedroom is where I notice it) constantly adjusts itself. It does the usual whirring for 30 secs or so when it first comes on but then at times every couple of minutes or so it does a shorter adjustment. If youíre trying to have a lie in that is really annoying! Not sure if there is a parameter setting I need to tweak or this is perfectly normal, in which case I need to get a new system because right now I just leave the rad off as Iíd rather freeze than listen to it! Any tips greatfully received.
