This controller use two-way communication with the evohome controller. The evohome Smart WiFi Thermostat is required for these radiator head to operate and control with temperature zoning. The HR92 radiator controller will fit a wide variety of thermostatic radiator valves (TRV). Adaptors are available for some older less well known valves - if you already have a TRV head in place it’s as easy as unscrewing the current TRV head and replacing the HR92 base by screwing it in place. Then snapping on the electronic head and locking it (no tools required). If you do not currently have a TRV in place you will need to consult an installer as it is possible that you will have to drain all or part of your heating system in order to replace the valve body. Enjoy accurate, comfortable climate control with this this radiator multi-zone kit. The wireless head allow you to create one zone. The evohome unit allows up to 12 zones, with potentially more than 1 head per zone. Once installed, the timing programs can be individually adapted to a daily routine. Choose up to 6 set points per day at the desired temperature. This slim, ergonomically designed radiator controller is made with a robust polycarbonate body for durability. It's battery powered with a two-year battery life and a low-battery reminder visible on the radiator controller screen. The flip-up screen can be positioned so that it can be easily viewed or folded away flat. Each unit features a backlit LCD screen to display the zone name, and local set point temperature. The local set point temperature can easily be overridden by turning the dial at the top of the radiator controller. Override temperatures can be set in half degree increments and are effective until the next scheduled change. There is an open window feature that recognises sudden temperature drop and shuts off the local radiator. The zone temperature changes made at either the evohome controller’s screen or via the remote app will change in real time on the screen on the radiator controller. In cases where the radiator head is covered and may not accurately read room temperature, a single-zone thermostat may be used as an accessory (T87RF). Not only are these well-made and feature-packed, they are easy to install, once the compatibility of the radiator valve is established.

I'm a light sleeper and it's never woke me. How often will depend on the weather, it will keep opening and closing to keep at 21 degrees. There is a setting on the mail controller that allow it to be a number of degrees off the required temp before activating which my help reduce that for you. **Q: Will these work with a steam heating system in the United States?** A: If they will fit the US thermostatic valves and the controller is the correct voltage and the steam is available at all times ...... it should work! **Q: Does this work with the Amazon Echo?** A: Not directly. You need to pair this to the Evohome controller. The Evohome controller is what connects to you boiler via the relay box. Then the Evohome controller connects to this TRV and controls it via a proprietary wireless signal. It’s not WIFI. The Evohome controller is wifi so you connect that to your home network and you will then have App control. Once you have that set up the Alexa integration can be set up. That will then give you the control you want. **Q: Do the radiator valves connect to the main house wifi, or do they use a proprietary wifi provided by the controller?** A: As stated they use a different frequency from wifi and do not have any interface to your network directly. They interface with the Evohome thermostat which then interfaces with your wifi and from there to the Honeywell evohome app and Amazon Echos (maybe Google, etc but I can only comment on Alexa as that’s all I have.) ## Frequently Bought Together - Honeywell Home THR92H1002 evohome Wireless Radiator Controller Head for UK, White - Honeywell Home THR0924 evohome Wireless Radiator Controller Head (Pack of 4) - Honeywell atf500dhw - ACS Kit for Evohome,White,285 X 228 X 68 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/48345108-honeywell-home-thr92h1002-evohome-wireless-radiator-controller-head-for-uk](https://www.desertcart.us/products/48345108-honeywell-home-thr92h1002-evohome-wireless-radiator-controller-head-for-uk) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-09*
