Honeywell DT90E Digital Room Thermostat + ECO is rated 4.4 out of 5 by 118.
Rated 5 out of 5 by from Effective and easy to install Bought to replace an existing analogue Honeywell central heating thermostat that wasn't controlling the temperature effectively. This new one is dead easy to fit (useful tips in other reviews), using only two wires and the existing screw holes. Haven't had it long but it seems to be far more sensitive than the old one and keeps the temperature in a much more narrow range. Highly recommended.

Rated 5 out of 5 by from Honeywell Thermo Simple fixing 2 screws required with link to controller to fix to red 7 black wires does require cable to be used and placed in suitable room, is supplied with batteries as this is a low voltage signal required.

Rated 1 out of 5 by from Waste of money I bought one of these as I thought a digital thermostat would be the way to go. Wrong! This model is supposed to be 'intelligent' but its stupid. Sorry I was going to write whats wrong with it but that would just take too long, in summary just dont buy it!

Rated 4 out of 5 by from Nice and simple. Good product, but instructions for wiring need to be better. If like me you're going from a 3 wire thermostat to this then you don't need to use the blue negative wire, i blanked this off with choc a bloc. Then the normal red live goes to B and the other live ( bit sure what you'd call it but mine is dark red with yellow sleeve on it) goes to A. Hope this helps.

Rated 5 out of 5 by from Honeywell Digital thermostat Bought this to replace my old Honeywell dial thermostat. Simple to fit only needs two wires took about 15 minutes. Displays current room temperature, is more accurate and looks smarter.
