Honeywell DT90E Digital Room Thermostat + ECO is rated 4.4 out of 5 by 94.
Rated 5 out of 5 by from Well designed and made item Excellent performance and control setting - take care to select higher power setting if it is used to control heater directly

Rated 4 out of 5 by from Easy to install and use Easy to install as a replacement for a twisty dial analogue stat. Old stat used two cables and an earth, this just uses the two wires (L&N) so you can put the earth aside in a connector block if you want. Don't care what anyone says, the clicking of the stat turning on and off is definitely much louder than a normal stat. Would probably wake you if you had heating on using the stat in a bedroom but if it's in the hall or landing then there probably won't be an issue with that! Follow the instructions and you'll have it set up in 5 minutes!!

Rated 5 out of 5 by from Replacement Replacement for old style Easy to fit and much more reliable than a old type dial version

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.
