Honeywell Home THR92H1002 evohome Wireless Radiator Controller Head, White, Made in the UK - Designed for UK Homes

Having purchased a Honeywell Evohome kit elsewhere, I found myself in need of further Radiator valves. I bought a couple on here to top off to the required number. Initial impressions are that they might be a bit delicate, so I would worry about kids running around near radiators pulling at them, or accidentally knocking them when walking past - especially with the screen tilted out. Saying that, they work well. It took me a while to fit the first one - Tip: Don't just screw them on, unclip the bottom section, screw that onto the radiator, and then push the valve onto the bit you've just screwed on. I'm no plumber, but this is honestly a 20 second job per radiator at the most - assuming you already have standard thermostatic valves already (these just unscrew to make way for these. If you don't, you'll need to bleed your radiators) Pairing is easy with the Evohome control panel. I had concerns about range, we live in a 200 year old house with solid walls. Even the furthest away radiators keep a good connection to the base unit. As these adjust the temperature automatically they aren't silent. You will hear a high pitched whine when the motor inside starts adjusting your radiator according to the temperature/your schedule. You soon get used to this, and all but the lightest of sleepers/nervous of dogs won't be bothered by it. You can also pair these with a separate room stat if the radiator is to be behind a sofa so the temperature is more accurate. Battery life is meant to be in the years - but simple to change when they run out. They take standard AA's. Time will tell how they fare. All in all, no complaints. Really pleased to be able to zone each room of the house independently!

These are a great investment and offer individual radiator control. You do need the base unit and wireless relays to match your system needs though and this can easily run up to £1000 to purchase and then be professionally installed. Once installed, it's easy enough to manage and the heads can be interchanged without any technical knowledge. Signal indications tell you how well each device is connectingb to base and their battery life. Multi fit adaptors provided in the box to fit different types of existing radiator valves. Good quality construction.

When I bought my house (new build) in 2013 these radiator controllers were installed by the developer as part of a Honeywell system that was run by an ATF800 touch screen controller and an iOS app. The system has worked very well over the last 13 years with no problems until one of these THR92H1002 units failed and I could not get it to work. In the box, you get batteries (which in my considerable experience last about a year), a display mounting which angles the display upwards making it easier to read without you getting down to floor level, a value base and an adapter (the last two I didn’t need as they are installed on my system already). In terms of the adapter they look simple enough to fit as does the value base, but if I didn’t have them installed already I’d be unlikely to attempt this myself. DO NOT install the angled display mounting piece until the end as you can’t rotate the unit with it in place!!! (as I found out). The unit comes with instructions on how to fit it, including a QR code that takes you to the WRONG PAGE on the Honeywell website. So I suggest you search the internet for “how to install Honeywell HR92UK radiator controller” which will get you to there eventually. Given that I have the base and adapter already installed it’s very simple to screw this on to the radiator, but I had to screw and unscrew it a couple of times from different starting positions to make sure it was square to the radiator at the end of the turning/screwing process. The real pain was binding this to the Honeywell controller as you need three hands or someone to help you. I’d misplaced the controllers instructions but they’re on the website. The main problem was that the menu which came up on the unit when I tried to bind it was not in English and it was a real pain to change the language. All in all it took about 5 minutes to get working, so my advice would be don’t attempt this yourself unless you have a bit of a problem solving mind, if you are a bit handy it’s easy enough to do There are already reviews on here about the noise of the motor, so you can read them yourself, I don’t mind it, it’s not too loud and certainly wouldn’t wake me up. All in all this was a bit awkward to get working (faffy for those in the UK) but now it is installed it is working fine. I’m still happy with my system.

Still the best system - recommended

I have used a lot of honeywell products in the past and they are a very well designed, quality and reliable brand. These are no exception but the only issue I have is the volume of the motor when it adjusting as it drove my wife mad. So beware when placing it in a bedroom with a radiator close by.

I have 16 of these devices throughout my reasonable sized house (5 beds, 2500 ft2). Before I installed Evohome, I was limited to heating rooms en-mass via regular central thermostat and rad controls. With the Evohome solution I am able to control each room discretely, according to usage which has reduced our gas consumption significantly (and made the house more comfortable to boot). Observations on these valves in particular: 1. They can be configured to detect a rapid drop in temperature (such as when a window is opened) and close down heating to prevent energy wastage. 2. They have local override, which may be useful to make your guests more comfortable, but can be locked out (as I have done) to prevent small fingers from fiddling with them. 3. During operation they do make a mechanical noise from time to time. This may initially disturb a light sleeper if heating is operating at night - or in our case early morning when the rooms are warming up. We have quickly become acclimatised to this noise and it doesn't bother us. 4. Batteries tend to last about a year, and whilst they do alert you when batteries are low, consumption is different from rad to rad and room to room - rather than change batteries piece meal, I have decided to make a day of changing all the batteries once a year (Amazon basic alkaline batteries are great). 5. Radio range is pretty good, despite the house being quite big I don't have any issues with them losing connection to the hub which is located in the middle of the ground floor (we have quite thick walls and lots of steel in the extension) 6. One device did manage to get itself into a mess - it tightened the actuator on the rad value to the point at which it couldn't release it. This was identified by the radiator not warming when it was expected to. I solved it by removing the head and manually releasing it. It hasn't had any further problems after doing this. 7. The associated controls (Evohome touch) isn't cleaner friendly, and until I had educated our cleaner I would find random rooms were unexpectedly hot or cold - it was as a result of her running a duster across the screen and pressing buttons randomly.

These wireless radiator heads work with the Honeywell Evohome system for controlling the temperature in your rooms separately. They work well, and have a nice clear display. They are programmable from the central Evohome controller or you can use the dial on top to adjust the temperature temporarily. The screen can either be flat against the radiator head or there's a little plastic widget which can be used to angle it outwards for easier viewing from above. Batteries generally last a year or two.

I've copied and pasted my review of the wireless controller review below this brief review of the radiator controllers as you're unlikely to buy one without the other. These take seconds to fit, assuming you already have TRVs installed. Otherwise you will need to replace the radiator valves with TRVs which is a bit of a bigger job as these are just the controllers that screw or clip on the top. They are easy to program and it can work as an override if you want to adjust the temp at the radiator with a quick twist and press of a button so you don't need to access the wireless controller or ap. Here follows the review of the wireless controller. I wanted to give this a few weeks before posting a review so I could really give a good idea of how it works. One of the key things I wanted to find out is if this system will work without connecting anything to the boiler. So just the Wireless controller and radiator controllers. I'm pleased to say it does. Im running this with a combined boiler and all is working well. The unit is easy to use and set up. Tip, sync with radiator controllers before you fit them to radiators its easier when everything is together. Programming is a doddle with the set up wizard. I'm still playing with variations but suffice to say its working well. You will need to fit or already have fitted TRVs. Retain the old heads as if you move you can then take this system with you. That's it for now. I will update in a few more weeks once the weather turns a little colder.

Ho montato quelli che avevo preso lo scorso anno e sono ottimi

Je confirme : aucune différence avec la version française. S’adapte parfaitement avec les têtes Danfoss ou Comap

Funciona perfectamente en radiadores españoles típicos, solo viene con rosca M30

Took a total of four minutes to install, two more to program. Works as advertised.

Ich kannte die Thermostate schon war ein Ersatz Bestellung. Der Vorgänger hat lange seine Dienste getan 👍🏻
