KETOTEK is dedicated to the research, production and sales of industrial and home automation products. Whether in Europe, North America or Asia, we have launched many reliable products. It is our long-term mission to provide consumers with the best quality products.
【Compatibility】 Flush-mounted, the WiFi thermostat works with most boiler/water underfloor heating systems. It uses dry contacts to control the boiler’s start/stop — the dry contacts are voltage-free, don’t supply power to the boiler and only provide an Open/Close signal. When the contacts close, the boiler starts; when the contacts open, the boiler stops. Confirm your boiler supports dry contact control before purchase.
【App control】 Simply connects the thermostat to WiFi to control temperature and settings from your smart phone via Smart Life/Tuya App. You can monitor your thermostats, adjust temperatures, create schedules and use a variety of options in the App from anywhere, anytime. Want to control and programme multiple thermostats at the same time? Just create a group directly in the app. 2.4GHz WiFi required (not 5GHz).
【Voice Control】 This WiFi Thermostat is compatible with Alexa and Google Assistant. Connecting to Alexa is as easy as setting up any other Alexa skill. Once connected to Alexa, you can turn on/off the thermostat or set the room temperature via your voice, without getting out from under the covers, especially in the winter.
【Create schedules】 Choose program mode, manual mode or holiday mode to optimize your heating to fit your lifestyle, and save energy and costs on your energy bill. The program mode features a choice of schedule settings, including 5-2 (weekday and weekend), 6-1 (Sunday different from the rest) and 7-0 (all days the same) scheduling with 6 time periods and temperature settings per day. It does not support different programming day by day.
【More Functions】 This WiFi Thermostat can be configured to detect a rapid drop in room temperature (such as when a window is open) and automatically pause the heating to prevent energy wastage. You can lock the thermostat to prevent others to change temperatures or settings through the wall display. More functions: temperature calibration, reset, memory function, anti-freeze function, etc. Power supply: AC 90-240V 50/60Hz, Output: Max 3A. The thermostat requires a 220V mains power supply.

Great WIFI Thermostat
I got this WIFI Thermostat to replace a basic unit for a combi boiler which went faulty. It programmed in to the SmartLife App and Alexa very quick and with ease.The unit is very nice looking and works very well, everytime. The controls and displays are very clear and simple to operate manually, automatically or by using Alexa.Easy operation within house and remotely to put heating up or down as required.The unit works really well with Alexa with simple commands..ie: “Heating 18 or Up 2 or down 3”.. can also question “Whats the heating Temperature” gives you instant temperature of house from anywhere. Also visible & controllable on screen or on mobile.The DIY Installation was fairly easy as I didnt need to go into the boiler for connections, but recommend a 40mm deep back box for unit & cables. I found connections clear, but I do have electrical background. If unsure you will need to get a Gas Safe/Spark Engineer in to install. Basically a great unit, good value which looks good and works extremely well.

A great item at a realistic price
I’ve been looking for a central heating programmer and thermostat to replace a battery powered one that doesn’t work with Alexa . This one fitted the bill and I ordered it.It arrived on time and I set it up on my workbench. I already have a Smart Life appliance so it was only a few seconds before it was set up and functioning. I was very pleased with the programming flexibility and only found a slight problem with the colours used in the app where some links were shown as white on a very pale grey background so almost invisible,The instructions for setting up were clear and easy to understand but I was a little surprised that there were no instructions about fitting the unit. Fortunately as an engineer I realised how it was mounted but wonder if anyone without that background would understand how to do that.As my CH boiler is switched on by a live mains connection to the wire from the boiler I could use the uncommitted relay output to simply extend that to operate the heating.Overall very pleased with the purchase and hope that it will last as long as the old programmer has.Time will tell but I do like the ability to control all aspects of my CH boiler from my iPhone and can turn it ona dnoff and set the temperature by talking to Alexa.

Works well and is value for money compared to others on the market.
The thermostat was easy to install and connect to the Yuya app. It works well but I discovered the accuracy could have been better when checked against a digital thermometer. The thermostat calibration can be adjusted from setting’s within the app. However, there is no mention of carrying out this procedure in the instructions so I have marked it down a star.

Fiddly installation, but overall a success
Overall Iâm pretty pleased with this unit. Installation was simple enough, however mine was complicated by two factors… firstly the unit is deeper than the thermostat it was replacing. Even with a standard size backplate, this new unit wouldnât fit. So I had to buy a âspacerâ to put between the wall and the unit. Itâs so much deeper, that even with this spacer, it only just fits, I very nearly needed two.Secondly it was complicated by the wiring for the floor temperature probe, specifically the type of connector at the back on the unit. In the box is a new temperature probe, this has a two thick metal ends which plug into the unit. There was already a probe in place, so rather than disrupt everything I wanted to use the existing one. In theory not a problem, however the new unit wouldnât take bare wires… no matter how much you tightened it they would slip out and the one time I did manage to get the unit mounted without them falling out, on power up it came up with a floor sensor error message.The solution was the cut the wire provided in the box, with the two thick metal ends, and join the existing wires to the new wire. Ultimately that worked, but was a bit of a pain.However now itâs installed and set up, Iâm pleased to report a few good things too.Firstly itâs really easy to use, either via the Wi-Fi app or using the controls on the screen. Itâs so much more intuitive than the traditional unit it was replacing which required a degree in jibberish to programme. Switching between the timer programme and manual control is easy and it works with my Alexa and again, this was easy to set up.Secondly, having suspected the old thermostat was faulty, this has given new life to an old underfloor heating system in our kitchen. There is now a nice toasty warmth underfoot and the ambient temperature of the room is greatly improved as a result.Pretty happy overall, but marked down one star for each of the installation issues.

Great piece of kit
I canât even begin to say how impressed I have been with this thermostat. I replaced one which even though relatively new was extremely difficult to set up the program times on and off. I switched it over myself which was an absolute breeze using the already installed probe. The app excellent and is really easy to use which meant I could program it exactly how I want without having to have the same settings Monday to Friday. It did easily connect to my Alexa devices so I can simply tell Alexa to set the underfloor heating to 30 degrees if I want to boost the heating in between. Only downside is the display which I think could look better and that some of the light leaks out from the sides which I notice at night but that really is a minor thing. Great value for itâs price

Useless!
Wifi connection does not work and terminals are the incorrect way up, should be at the bottom as a like all other units are of the many i have fitted over the years

Works nicely and replaced my old Drayton controller
Good quality. Looks so much nicer on the wall. Works well with 3 cable boiler setup. I can now operate heating from anywhere.

Hicimos una pequeña reforma en casa y nos aventuramos a domotizarla un poco.Que gran descubrimiento cuando compramos este aparato, se instala de una manera súper sencilla, se conecta a la caldera de manera fácil y clara.Es programable y temporizable, se enlaza con los asistentes de voz de una manera muy intuitiva.Posiblemente haya otros mejores con más funciones y de mayor precio, pero si quieres algo bueno, bonito y barato, que cumpla su función y te haga la vida más cómoda es un producto altamente recomendable.irte a pasar un fin de semana y poder programar la calefacción para que a la vuelta esté la casa calentita, es posiblemente una de las sensaciones más gratificantes que puedes pedirle a un aparato de estos.

It would have been easier to set it up if the manual described the function better. But after some experiments it works as intended.

Die Thermostatsteuerung ist perfekt für meine elektrische Fussbodenheizung im Badezimmer. Sie wird von der Smart-Life App angesteuert. Dort kann man komfortabel Steuerzeiten und Temperatur einstellen. Kein Knöpfenprogrammieren am Gerät nötig.
