## Overview

The Honeywell ATF500DHW ACS Kit is a wireless hot water control solution designed for Evohome systems. It includes a cylinder thermostat, transceiver, optional insertion sensor, and a wireless relay box to manage your hot water zone valve. Battery powered and Wi-Fi enabled, it offers programmable temperature control and remote smart home integration, making hot water management effortless and energy-efficient.

## Description

The hot water kit consists of a Wireless cylinder thermostat, transceiver, optional unvented cylinder insertion sensor and an additional Wireless Relay box for control of the hot water zone valve.

Review: Simple to install if EvoHome already in place - 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
Review: Great product poorly packaged by desertcart - The item arrived inadequately packaged and the box was damaged so I returned it because I suspected the contents were compromised.

## Questions & Answers

**Q: Is this a self install or do you need a plumber?**
A: Easy if you know basic electrics if not local plumber should have it sorted within the hour

**Q: Would you also be willing to send to the Netherlands?**
A: Hi,

You would need to check this by adding the items to your basket, it will advise whether overseas delivery is available or not.

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.

### ⭐ Great product poorly packaged by Amazon
*by M***M on 27 October 2025*

The item arrived inadequately packaged and the box was damaged so I returned it because I suspected the contents were compromised.

### ⭐⭐⭐⭐⭐ Glad I found this before buying separates
*by A***T on 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.
