Great piece of kit
I can’t 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 it’s price

Excellent control, easy to install.
Attractive to look at and simple to install thermostat with a clear display - worked without any issue when connected to an existing system from a different manufacturer. The smartphone app is clear, easy to use, and reliable, making programming easy. Yes, we don't make too many changes to the settings now its settled in, but it was a more pleasant experience to program from a chair, rather than crawling around on my knees with paper instructions printed in a micro font. It cost less than 15% more than a similar non-wifi-connected unit. Very good...and another toy for the man of the house.

Low cost replacement for Warmup controller
We had not used our underfloor heating for a while because the controller on our Warmup system had failed. I saw this and was a bit skeptical at the price. However, it was easy to fit and set up on the wifi. A award 3 stars because the metal frame needed one of the holes enlarging in order to mount properly, but this is not a great inconvenience. The heating and thermocouple wires both just fit into the device. Our controller is in an awkward location so it is so much more convenient to use wifi to control the heating. It is also much easier to set up the program on your device, compared to prodding buttons on the controller itself.

That is dreadful unfortunately.
Well, I bought this some time ago for a customer, but they said don’t fit that, they never work. So I kept it for myself.So today I thought I’ll replace my own thermostat controller with this one, it’s got an App and Bluetooth/wi-fi controller. Fantastic!However 3hrs in and still doesn’t work.First the unit back plate has No holes for the screws for Pattress box, so out to the van to get the drill.Then let’s pair it up with wi-fi, yep that’s not going to work either !!Let’s do it manually then… and if you know, all these China units are a nightmare to program with the touch screen, but here we go and it’s working now. Still only manual control, as zero connection to wi-fi which is annoying.As for The function menu, we’ll…. it’s the same as all the other China ones dreadful to navigate, difficult to see and you can never throw the instructions away as it’s a mission impossible without it.Anyway would I recommend, NO, reason connectivity usless, ease of programming horrible, fitting rubbish and customer service? Well we will see if they ever reply.Have a great day everyone.

Just what you need to replace an old difficult to set up controler.
I purchased this product to use it with my underfloor eating and to replace a really difficult to set up controller. Setting up the Wi-Fi wasn’t that intuitive but following the instructions line by line and not jumping ahead soon, got it up and running. Using a smart app also helps and allows me to do a lot more useful routines and the previous controller which was a nightmare to set up.

Fiddly installation, but overall a success
Overall I’m 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 wouldn’t fit. So I had to buy a ‘spacer’ to put between the wall and the unit. It’s 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 wouldn’t 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 it’s installed and set up, I’m pleased to report a few good things too.Firstly it’s really easy to use, either via the Wi-Fi app or using the controls on the screen. It’s 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.

Easy to use device
I bought this item to replace the old thermostat.Only one day of use, so I cannot comment on this product in the long-term. As for installation: I am not very familiar with electrical work, so I had my mate take care of all the wiring and installation. He understands electricity (but not an electrician), and it took him approx. 5 min. to install the new thermostat, so I guess it is easy.After turning on the device, the set-up, configuration and connection to the WiFi took less than 5 min., it was super-easy. The device works good, no issues with remote control via mobile app, overall good product.

buen termostato wifi
Es un buen termostato wifi y muy sencillo de instalar. Compramos uno para probarlo y, tras ver el buen resultado, hemos ido adquiriendo más unidades para cambiar progresivamente todos los de la casa.

Ottimo termostato👍
Molto carino e semplice da installare.L'ho installato in bagno per collegare la serpentina elettrica a pavimento. Attualmente devo ancora settare bene la temperatura tramite la sonda esterna, ma sembra funzionare tutto bene e tramite l'app è molto Semplice impostare le varie fasce orarie, blocco bambini, temperatura ecc.

Chauffage électrique au sol
Bon thermostat facile à installer et à connecter. Il convient pour un chauffage électrique au sol et requiert le raccordement de la sonde pour un fonctionnement optimal.
