## Description

Simplicity and control are at the heart of Honeywell Home evohome system. This set includes everything you need to setup your thermostat and boiler, plus two radiator heads for seamless, wireless integration. The Honeywell Home evohome Smart WiFi Thermostat offers flexibility to customise your system to suit your surroundings, so everything’s just how you like it. Use the full-colour touch screen and easy-to-follow menu to schedule, create zones, and personalise your temperature and hot water settings at the touch of a button.

Review: Fits well with the Honeywell home system. Installed easily on my dutch radiation. This valve comes without a screen and instead only can be adjusted with the Honeywell central screen or the phone app. It's useful for hallways or attics that you don't usually enter often.
Review: 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.
