More comfort – you can easily control the temperature of any room or area in your home. Evohome is a wireless system and can be installed very easily, without having to do any work. More Control – Gone are the days when you had to get home and get its heating on – with evohome you can do it from your smartphone. Save money – By switching from a conventional thermostat to a zone by zone heating system such as evohome, you can save up to 40% on costs. There are two types of thermostatic heads: THR092 (with backlit screen) and THR091 (without screen).
Features & Benefits
The intelligent Zoning
evohome is a heating system that allows you to create up to 12 comfort zones in your home. In the same way that the lighting of a house is not controlled by a single switch, there is no reason that the heating is controlled by a single thermostat for the whole home. The intuitive evohome thermostat makes it easy and quick to create comfort zones throughout the home or to take this task off later. As evohome is a wireless system, you have no work to plan out to install the product.
Remote access
With the Total Connect Comfort evohome mobile app, you can increase the temperature of your indoor area by zone from your smartphone.
If you have an evohome security alarm, you can also control your alarm with this same app.
Stylish and intuitive design – evohome adapts to your needs
evohome is suitable for any home. Areas can be added later or changed if required.
Thanks to optimising and self-learning, evohome can be installed anywhere and meets the needs of people who want more comfort, more control and want to save energy.
Features & Benefits
AA Energy Efficiency
The THR092 programmable radiator head has received the highest AA energy efficiency label awarded by eu.bin. Wireless programmable radiator heads communicate directly with the evohome multi-zone programmable room thermostat through 868MHz bi-directional communication.
The THR092 head has a tilting backlit display for optimal reading. The adjustment dial allows you to manually adjust the room temperature without changing the recorded schedule. The “Open Window” function saves even more money: if the temperature drops suddenly, the valve closes to avoid unnecessary energy costs.
If the radiator valve is inaccessible or covered, it is possible to add a T87RF2041 wireless thermostat which will work as a temperature probe while the valve will act as an actuator
Easy to install
Thermostatic heads fit on most thermostatic valves on the market with or without adapters. There is no need to empty the installation.
– Valve type M30 x 1.5 mm.
– Type RA, RAV, RAVL anfoss
– Giacomini.
– Comap and Herz.
The THR092 head has a blue backlit tilting display, shows the set temperature and room name.
Compatible with IFTT and Google Home
The evohome thermostat is compatible with Google Home and IFTT “If This Then That”.
With the IFTT protocol you can create scenarios. For example, you can decide to create the following scenario: if I turn off my alarm, I want the heater to set at 21 °C.
Your evohome is the best friend from Google Home.
Connect to Google Voice Control Assistant and simply use voice control to set the ideal temperature in your home. Say “Ok Google” to get started.

Brilliant for a smart home
Returned as it turned out I didn’t need a replacement after all, but as I have a full house Honeywell installation and have been using these for several years now, I can attest to their quality. They perform brilliantly, using their own proprietary radio system for communication rather than wi-fi, and the difference the whole system makes to the comfort of the home throughout the day, plus saving on gas and ability to control from anywhere you have an internet connection makes it a brilliant investment.

Works well
I bought this to replace a lightwverf radiator valve which had had a battery leak.Connected to Lightwave with no issues and has worked well.It is quieter and looks better.The one issue is the physical installation instructions was not over clear, so took me awhile to figure out how to but eventually got it to fit.

Not an easy fit
While there are a lot of options with this radiator controller, they do not make it easy to understand how to fit them..While I can usually work these things out, what I have got fitted is not working as anticipated.While cheeper than Hive, I am not as convinced that they are a good fit for me. Will be sending back
Liam Thomas –

Easy to fit and performs as expected

Seems like a pretty good bit of kit
I have 4 HR92’s on a ( delayed ) order but I got a HR91 from a plumbers merchant since I needed one of these for a physically tight installation.Removing the Danfoss RAS-C TRV was a bit of a faff only because the installer seemed to have torqued the connection bush near to breaking point.Having removed the TRV, installation was OK but it took me a few attempts to work out what bits I needed and what to do to mount the unit. Probably utube vids on this. NB the actual connector has to be freed from the base of the TRV – all completely obvious when you have sussed it out and worked out what the IKEA type diagrams actually mean.Only had this operating for a few hours but it seems to work OK. You can manually ( using the two front buttons ) fully open or fully close the valve ( or set it to an intermediate point ).I have it linked to a lightwaveRF LInk L2 hub at the moment – mostly because I have got one.Note: I found that when first paired/bound with the LWRF L2, the battery level and valve state were at zero. Just take out the batteries and reinsert – this seems to sort that bug.All in all pleased so far.Edit: first TRV took about 30 mins to install, second 5 mins, 3rd all done in 2 minsNB I have NOT had a reported problem with the HR91 in that it will not wind the base valve stem fully in or fully out with some Danfoss valves.I wonder if you can use Lithium batterries in it instead of NiMH – to give a longer battery life ?
Product works well. Disney + is not available on this product even though tye advert say ls it is –
Not good for the momey
I bought these to control the temperature in each room.. They are not good at reading temperature or some are faulty can’t work out which. Currently says it 22c in front room yet it freezing and have had to set thermostat to 24 just to get it to come on. Have spent the last few weeks adjusting temperatures way above normal just to get the radiators to come on. For the money not worth it.

You Don’t Receive What’s In The Bundle – Keep Away
The advertised bundle purchased consisted of1x evohome Thermostat1x linked Boiler Relay2x THR091 Rad Controllers.Only received the Thermostat & 1x THR091 (ie associated Boiler Relay & 1x THR091 missing)Repeated calls to Customer Services & subsequent replacements failed to rectify. In fact, the cack-handed way the refund’s been organised, it looks like I may not receive what I’m rightfully owed – we’ll see !!

Dovevo sostituire una valvola del sistema Honeywell in un locale in cui non serviva display né controllo manuale della temperatura. Arrivata, installata in 5 minuti, perfetta come tutto il sistema di gestione del riscaldamento domestico Honeywell

Werkt in combinatie met Evohome en ook de app. Programmeren via de app lukte niet in eerste instantie maar via de Evohome bediening kon je gewoon een dag indeling programmeren. Toen die er eenmaal in zat kon je ook via de app deze thermostaat programmeren.
