Â by Bigboack Spot on for saving energy
I bought this as an add on for my central heating and fitted it within minutes, two wire operation from boiler to the unit so bear in mind it's not wireless, however I was only going through the wall to living room, very easy to fit and does not look out of place next to light switch. You won't go wrong for price and it will save money on your heating, so it will pay for itself in 12 months.

A better designed product than the former unit although not quite a straight swop, the terminal connections are different. The unit controls more accurately being able to control to 0.5 degree C rather than a full degree C.
Rated 3 out of 5Â by Benny10 Disappointing
This was fitted by plumber along with a new boiler. Like many electronic products the instructions and design are overly complicated . However my main problem is that the programme 'froze' on occasions meaning that the boiler stayed on and the temperature kept going up. We only spotted this when we woke in the middle of the night. None of the buttons would work, the display was frozen and the only thing to do was to remove the batteries. As soon as I put the same batteries back it worked normally.
This happened on a couple of occasions. I contacted Drayton who said that it seemed that there was a problem with the chip and sent me a replacement. It is now doing this again so I will replace it with a non-Drayton thermostat.
An earlier reviewer (SBEDIYer) seems to have had the same problem but interpreted it as failing batteries. I suspect he had the same problem as me. The impression I got from Drayton Customer Service (who were very helpful) is that this is a common problem.

I bought the Digistat+3 a year ago and was constantly confused about what it was doing. It seemed to turn off the heating before the target temperature was reached and randomly switched on for a couple of minutes at a time during the night. After belatedly reading the reviews here, I now understand about the crazy algorithm built in to this device which means that it doesn't actually do what it says in the instructions. The whole thing seems pointless to me because I constantly have to adjust the temperature to get the heating to stay on, so I might just have well used a simple switch. It clearly isn't worth the money and there are better devices at just over half the price.
The manufacturer suggested that I buy a different unit! I suggest that you do too.
