Honeywell DT90E Digital Room Thermostat + ECO is rated 4.4 out of 5 by 89.
Rated 4 out of 5 by from Thermostat Easy to fit and set up. No problems wiring up, didn't use the instruction pictures as the wiring diagram was printed inside the unit. Old stat was a 3 wire mechanical one but this adapted perfectly well. Seems to warm the house up quite quickly and then cut in and out as required.

Rated 4 out of 5 by from Easy replacement room thermost This central heating room thermostat replaces the old wired mechanical stat in minutes and provides current temperature digital display and simple up and down buttons to set the target temperature. It also provides the ability to set a period of countdown-time to temporarily change the required temperature setting at that moment. This is a very good product when not wishing to go wireless with an expensive device.

Rated 4 out of 5 by from DT90E I was after a digital thermostat for my customer that was simple to use, could be 'locked' to stop unautorised access and not wireless. This product can do this if a little clumsily. Not sure about performance and reliability yet but MK & Honeywell have a good reputation

Rated 5 out of 5 by from Good stat Reliable temperature gauge and adjustable +\- 3°, handy should you need it to reference another thermometer, seems well made , instructions a bit vague on its set/ up use, basically pictograms , so if you're good at assembling flat packs you're on a winner, very happy with the purchase.

Rated 5 out of 5 by from Works great! Easy to fit and works great. Make sure you do not connect the neutral wire if you have one. I put mine in a small connector block and left it behind the thermostat.

Rated 5 out of 5 by from Great Stat Great stat. Took 10 minutes to fit and looks a lot better than original stat which looked like something from the 60's. Wiring instruction were straightforward. Only requires a Live and SwitchLive so no Neutral needed. Only downside i would say is the limited user instructions for its features like the eco button. Apart from that its a great product for the price
