Rated 1 out of 5 by Honeywell DT90E Was ok for a few weeks. Now started loud clicking every 10 minutes. Why was it quiet but now too loud. What's changed or broken? Instructions are rubbish. Frost setting only works if the boiler is on! Does nothing if the boiler timer is in the off part of the cycle. This is not obvious from the instructions. This is a pointless feature because does not work with a Honeywell ST9400C programmer! Has anyone got a refund? 8 Oct 2015
Rated 5 out of 5 by Honeywell DT90E thermostat Anything made by Honeywell is well made & reliable, which is why I bought it. Very easy to install. Very accurate. 31 Jul 2015
Rated 5 out of 5 by Super unit Another super reliable Honeywell product. Easy to fit, and more stylish than the old one, but also importantly more accurate! 31 Mar 2015
Rated 1 out of 5 by Not for quiet environments It does its job fine. BUT... It is really noisy! We installed it in a two bedroom flat. The click it makes every time it switches it heard all over the flat. It is so irritating that we are having to replace it. I sent a email to Honeywell Tech about it and they didn't bother to reply - hence the one star rating. 13 Mar 2015
