Easy installation

"Bought to replace 4 year old defective unit, where the display had all but disappeared (hopefully this will last longer). Didn't need the receiver box as existing one was ok, so could have saved some money. However, to synchronise the new unit with existing receiver was an absolute doddle (a 5 minute job that actually took 5 minutes). Unit now working perfectly & is easy to program, use & understand."

Great Product

"I used this to replace a Drayton Digistat system which was unreliable, I kept having to re-pair the controller and the base station.
It works well and to the guy who gave it 3 stars because it isn't a 7 day programmer, you should have purchased the right unit, Honeywell do a 7 day unit as well you just ordered the wrong one."

Best ever

"I've been using this for over 3 years and must say it's great. Reduced energy bills, never failed and low battery indicator started flashing recently.
I don't know why prev person gave it just 2 stars.
You don't buy Renault Clio and then complain that it's rubbish as a Trade Car.
If you need 7day programmer go and buy 7 not 1 day one!!!
Great product but bit pricey...

Expensive Replacement
8 Nov 2014
By Amberman

"My existing system had a Honeywell Wireless thermostat which worked very well until the display disappeared, a common problem apparently. I bought this replacement from screwfix but unfortunately it comes as a complete package, I didn't need the relay but the thermostat itself was easy to "rebind" with the existing relay so a minimum of work was required. I have since been advised that you can buy a similar thermostat at a fraction of the price of this that is more reliable but I would have had to change the relay. When this display disappears that's what Ill do!!"

"I found no difficulty in installing and setting up this thermostat even though I'm approaching 90 years of age. It does just what I want, and does it well, and from previous experience of this manufacturer's products I expect it to be very reliable."

Flawed for price...

"This doesn't allow for 7 day programming so if you want the GCH off during the week and on all day at weekends, tough luck. A shame as the CMT927 which is what I bought after returning this was only a bit pricier and allows 7 day programming."
