Rated 4 out of 5 by Tricky, but good overall. ...bit of head scratching to figure out the wiring diagram as its not clear what configuration you should go with and the operating instructions and description of functions are poor. Having said that, after you have figured it all out, it looks great. Nice neat simple and updated look and accuratley monitors the room opposed to the dial solutions you can buy. All in all, thumbs up. 13 Jun 2016
Rated 5 out of 5 by suits 2 wire or 3 wire had a bit of a cafuffle to understand fully the wiring requirement but sussed it. I had 3 wire set up on previous thermostat... this new unit only requires the live and the switch wire. I didnt need the neutral. Its because its a battery operated unit and only needs a circuit made to switch on or off. neutral just terminated behind unit. neat tidy simple digital thermostat. Nice. 22 Mar 2016
Rated 1 out of 5 by Noisy Two things wring with this: 1. When I got it home, I could see it had already been used (screwdriver marks on the case tags and the battery was already running). Not happy, but if it works OK then I wouldn't really mind. 2. It is REALLY NOISY! The regular CLUNK noise as it turns on and off in the lounge is more than a bit irritating. It is much louder than the stat it replaced. Based on the above, it's going back to Screwfix ASAP for a refund (selling me something that isn't NEW is enough to ensure I can get a refund). For the price I expected something better than this. Will go for another brand. 5 Mar 2016
Rated 4 out of 5 by Good replacement Used to replace old honeywell manual thermostat. Managed to have same screwholes and was a simple replacements. Just use live and switched live. Neutral and Earth are redundant. Would have liked a backlight. Seems to be accurate. 26 Jan 2016
