Honeywell Home T3R Wireless Smart Thermostat Kit - 7-Day Programmable Wall Thermostat with Intuitive Controls - 868 MHZ - Large Backlit Display, Flexible Scheduling & Compatibility

This was the perfect replacement for my broken Drayton Digistat +3. Installation took 10 minutes. No extra drilling as hole positions exactly the same as the Drayton. Work great so far! And a bargain for £40!

The screen on my old CM907 Timer/Thermostat failed and I found this M3 Timer/Thermostat an excellent and more functional replacement for the CM907. Very intuitive and easy to use menu system with more options than the CM907 (1 hour boost facility to name one enhancement). Although I will say the instruction sheets are more aimed at Trade or Professional Engineers / Installers than DIY fitting. But if you are familiar with programming any modern control device with a GUI interface, it is very similar to any other and actually quite easy to program. I note a lot of people complaining about the outer flap not closing properly and springing open again and having to use Blu-tack to hold it down... Don't believe this is a issue with design of the M3 itself, more the fitting instructions not being quite clear enough of how to fit the main unit into the wall/back plate. Initially my flat did keep springing out initially after following the installation diagrams as shown, but I found out as long as you firmly clip the top of the main unit in first like a hinge and then pivot it firmly downwards, clipping the bottom in last, this should then be a tight fit and the flap then close perfectly. Well mine did after doing that. I gave the M3 unit 5 stars all round as long as you understand modern GUI programming techniques and install it correctly. But would reduce this to 4 or less stars for the included M3 installation and programming instructions which could/should be better. I believe they are not aimed squarely at DIY installers without some basic skills and knowledge. Hope it last as long and as reliable as the CM907

We had one working fine for a couple of years, I accidentally knocked the thermostat off the wall and broke it. Had to buy the full pack to replace the thermostat unit, the receiver was working fine. One star off for Honeywell's "instructions" to pair the receiver and thermostat, they were less than useless!!! Googled a friendly handyman who walked the pairing process through in human language; now it's all working perfectly again. All in all a good system, whether you prefer to control manually or set timers for your heating. Just be careful if you do use the wall mounting (it's not flimsy, I was clumsy)!

This thermostat replaced another type which had become unreliable. It came pre-programmed, which saved a lot of time on installation. The most notable difference is that it is much more sensitive than the old thermostat it replaced. This saves money as it is more economic in use. I would certainly recommend it if you are looking to install a wireless control for your heating system

Excellent. Product.

Easy to setup . 7 day setup . 6 triggers per day . 1 zone. Battery operated. Receiver is wired in to a newish vallianr ( by gas engineer) . Not as sophisticated as a smart thermostat though. Temperature is accurate within half to 1 degree. Checked using another instrument .

Smart modern look. Easy to fit, my system just requires a two wire thermostat. Reasonable price. The instructions that come with it are not good, I had to resort to a YouTube video to set it up.

All as manufacturers description. Delivered on time and all for a great price.
