Honeywell CM727-7 Day Wireless Programmable Room Thermostat

Very good used it before

Perfect for my Honeywell Combiner's boiler. If your existing wall thermometer is only connected by two wires you will need to be able to read a circuit diagram and be confident in running a separate 240 volt supply into the rear of the wall unit.

I think I just gave this a 2 star by mistake.it’s brilliant as long as you or the installer set up the (optiimation mode )this learns how long your house takes to warm up and turns the boiler on at different times depending on how cold it is

Ordered 2, only the one worked.

Had to replace one that didn’t work anymore, new one works just fine but a a little expensive

Most suitable to need Disliked nothing

The electrician had it installed and working in 15 minutes

does the job
