Honeywell HomeTHR99C3110 Smart Wireless zoning Thermostat, White, 139x101x21mm, Set of 2 Pieces

After much research, I found this to be easily the best smart thermostat on the market and it goes the whole way by controlling individual radiators in addition to the central heating boiler. Every room has the right temperature at the right time.It's been about 3 months and we have not experienced any issues controlling this system remotely. Additionally, though all the controls on the thermostat are not available on the smartphone apps, this is not really detrimental.We bought 8 of the HR924UK radiator thermostats to go with this and the pairing went quite simply by following the instructions. I already had a very basic wireless thermostat which had been installed professionally, so I was able to connect the wireless module (this is separate from the thermostat but comes in the box) myself by following the wiring diagram at Honeywell's website for installers. Note that if you don't already have a wireless thermostat or you have the smallest doubt about connecting the wireless module, get a certified professional to avoid risk to life and property.Once everything is installed, you're on your way - you can name each thermostat around the house and decide what the temperature should be at different times of day in each room (the thermostat allows up to 10-minute precision). The thermostat touchscreen comes with a wizard to make this simple, or you can control the schedule with more control.The HR924 radiator thermostat regulates heat by opening and closing the valve as directed by the programmed schedule. There's a little noise as the motor turns, but after a while, you learn to tune it out. This combined system of the touchscreen thermostats and radiator controllers is very well thought out and includes options like always making a particular room a little warmer or cooler than the measured room temperature and showing which room(s) have caused the central heating boiler to come on. There could be some improvements (the battery life when the thermostat is moved from the base seems short and some features could be made more easy to access) but this has been one of my most satisfying purchases for a while.

Finally finished installing this system and would like to say that it is brilliant.Total control of everything to do with your heating.The main control panel is easy to use and setup. The iPhone app for is even easier. Works on the home Wi-fi or if your not at home works on mobile data too!I have 11 zones setup at the moment so there is even a spare zone left just in case we extend the house.The only thing I would say is that the installation manual could be slightly clear on some of the instructions, but I would like to add the the Honeywell website is very good so if you are installing one of these systems remember that the website is definitely worth having a look at if something is not clear.Very very happy with my purchase.

The good points about this control panel are that looks good and has lots of features for controlling the central heating system. It's pretty straightforward to use and the instructions provided are easy to follow to get you started.I would have given this device an extra star but for a few things which I feel could be improved. Firstly, the touch screen - it's not very responsive and I find I often have to press on the screen several times before it reacts. Secondly - since this device connects to the Internet, there ought to be an option to export your settings (that would also open up the possibility of being able to save more than one profile for each connected device). Lastly, the idle screen - it's way too bright and there ought to be a way to make it less bright without having to reduce the brightness of the settings screens. An option to have a white clock on a black background (as is currently available in night time mode) would be a good feature and there should be an option to completely turn off the idle screen at night as even with the white clock on a black background, it still lights up my bedroom if I leave the door open for ventilation.
