Thank you, Plumbworld **Q: Does this control the temp of your hot water or just allow you to measure it ?** A: It is both the thermostat to tell your Evohome what the cylinder temperature is, and the relay to switch the hot water valve to open or close. Usually the valve opening actually drives the heat demand from the boiler. **Q: Can this work on it's own? Recently invested in the netatmo to control my heating and the hot water is running on the own programmable timer.** A: No I don't think so. It's an add-on to the central heating unit to control your hot water remotely. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple to install if EvoHome already in place *by on Reviewed in the United Kingdom 15 February 2025* Box was a bit tacky and a cable in package was tied with masking tape suggesting I’d received a return, however product appeared okay.As for the HW kit itself, it’s working exactly as I expected and took about 1/2 hour to install.I already had the EvoHome in place controlling my central heating. I also had a Honeywell ST9400 programmable CH/HW controller still in place. CH was always let on continuous (as EvoHome dealt with scheduling and power toggling). It was only used to turn my HW on/off. That was up until a couple of days ago when it decided to stop working.Rather than pay £100 out for a new ST9400, I decided to purchase this kit instead and let the EvoHome control my HW as well.I simply removed the old programmable ### ⭐⭐⭐⭐⭐ Glad I found this before buying separates *by on Reviewed in the United Kingdom 28 December 2022* It's a boiler temperature sensor and a relay in one box, for less than they might cost separately. You'll need both if you have an S or Y plan heating system, as well as the base kit which has enough to control the heating but not hot water.It also contains instructions, including suggested wiring diagrams. I'm competent at dealing with mains electricity (always isolate what you're working on!) but having the diagram helped me have confidence in what I was doing, without changing any existing wiring beyond removing the seven day timer that was in the house before. And unless you have a really weird setup, you shouldn't need to change how anything is wired except for replacing the timer. ### ⭐ Garbage *by on Reviewed in the United Kingdom 11 May 2026* electrician cost a fortune and never had it working properly...after one year the whole system is broken. Garbage and should not be for sale. ## Frequently Bought Together - Honeywell atf500dhw - ACS Kit for Evohome,White,285 X 228 X 68 - Evohome smart wireless zoning thermostat - works with Alexa - Honeywell Home evohome Wireless Radiator Zoning Kit --- ## 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.is/products/52057287-honeywell-atf500dhw-acs-kit-for-evohome](https://www.desertcart.is/products/52057287-honeywell-atf500dhw-acs-kit-for-evohome) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-09-23*
