Rated 5 out of 5 by from Honeywell Thermostat A good product, at a good price from Screwfix, that accurately regulates the temperature. Neat, easy to read and fulfills it’s intended purpose.

Rated 4 out of 5 by from Control at a very good price This stat control is much better than the mechanical ones. It holds the set temperature stable, and is a doddle to change to what setting you are looking for (and is accurate to half a degree!). At this price why pay more?

Rated 5 out of 5 by from Excellent Customer Service Bought this Honeywell DT90E room thermostat to replace a broken old manual one. Had an issue with the first as a fault with it but in true Screwfix style they replaced it without quibble and the item is awesome, simple to fit and works a treat also reduced gas consumption which is a bonus. Thank you Screwfix Cannock excellent pleasant friendly knowledgable and helpful staff :-)

Rated 2 out of 5 by from Does the job, but with issues Working fine and does what it's supposed to, but 2 significant issues with the product: 1. as several others have pointed out the fitting instructions are poor. The wiring instructions are not fit-for-purpose. It shouldn't be left to trial & error or helpful review comments to work out how to install the product. 2. the clicking noise it makes is quite annoying. It sounds like a light being switched on loudly. How annoying it is probably depends on the type of wall it's fitted on, but in a plasterboard wall in a modern house it's very audible. For the first few evenings, I thought it was my kids getting up out of bed!

Rated 5 out of 5 by from Great value thermostat Purchased this thermostat to replace an extremely old manual dial thermostat that wasn't working correctly. Couldn't recommend this new one more as for the price it does exactly what it needs to, and it is great to be able to see what temperature the house is actually at. Didn't fit it myself as we had to get the location moved so I cannot comment on how easy it is to replace, however, it looks much better than our original one and have no complaints at all about it yet.

Rated 5 out of 5 by from Looks the business Looks a tidy unit. Not fitted yet but see no real problems. Has to be flush mounted which is not clear from detail s but I can cope with that. The instructions are in pictogram form which is a bit of a challenge for me. I prefer written instruction. But Honeywell offer very good support so if you are like me, fear not! Help is readily at hand. Cannot rate performance or reliability but other reviews are good. So let's live on hope!
