Honeywell Home Smart Radiator Thermostat Valve/HR 27 ECO ETRV/Programmable Thermostatic Radiator Valve/Digital Intelligent Central Heating Controller/White

Its good, because you can make unused room to heat at diferent times if you dont need or you can setup diferent temperature. Only menu its bit complicated but understandable.

Device works well, but programming interface is very unintuitive, instructions supplied and on the web are very unhelpful

This programmable radiator is an excellent and well designed, cost effective solution to zoning your central heating without resorting to apps, controlers such as "hive" or alexa type smart speakers. The bad part is the instruction manual is unfathomable. What comes with it tells you nothing about how to programme it. Most of the page is taken up with multiple language options. The good bit is that that there is a link to video instructions on how to programme and use the TRV. Great idea but that doesn't work. I mean that you can watch the videos but they are nearly impossible to follow. In an attempt to be multi language, there is no narrative, just elevator music. The presenter is obviously familiar with the product so pushes buttons quickly and silently. Blink and you miss what he did. As my wife said, its a bit like someone teaching you to solve the Rubrics cube by silently doing it in front of you, as fast as possible with no explanation of the method. I see that Amazon offer discounted "refurbished " controlers. These are really returns......which I fully understand as the instructions are abysmal, the product is great. Honeywell, please take note: Make an English soundtrack to your video and pause it between actions to let people follow what is happening.

The supplied user instructions have obviously never been tested to see if people can follow them. By people, I mean that, say, twelve year olds should be able to follow them, not PhDs. However, once learned it will only take ten to fifteen minutes to set up each one. Here are some notes I made for myself. INTRODUCTION The thermostat turns the radiator on and off: 1. For periods of the day 2. When on, at one of three specified temperatures It is useful for rooms that are not needed when the heating for the rest of the property is on. For example, rooms that will not usually be used until the evening and can remain unheated until then. BUTTONS (this refers to HR27) It’s got five buttons, which I will refer to as: 1. Menu (grid symbol) – offers options 2. Select (O) to select and save changes to a parameter 3. Up - increase parameter 4. Down – lower it 5. Mode (leaf) – set it to run automatically or manually, or take it off the radiator INSTALLATION The basic installation is: 1. Power up by opening battery cover and pulling off the yellow tab 2. Set the language to English (This is parameter 1, option 2. The full list 3. Set the time and date 4. Adjust rotation - even if vertical it is useful as you will look at it from one side or the other. 5. When it says MOUNT (or UNMOUNT) I assume it means it’s safe to fit it as the valve will be open and you won't press against it (not explained anywhere). I found removing the old thermostat and fitting the HR27 simple and easy. 6. Press Mode to cycle the valve (no idea what this does, but listening to it grind away, it seems to adjust the physical connection onto the valve. Again, not explained anywhere) SET UP The set up is: 7. Program the time and temp schedule. a. Navigate to the Set Temps using Menu and Select b. Keep the Mon to Sunday setting, or change it for more sophisticated scehdules c. Adjust the High, Medium and Low temp settings (in 0.5 degree steps - eg 20.5) d. Navigate with the menu and select buttons to get to the Programs f. Then program the periods in sequence: i. Select takes you to the next period ii. Menu takes you back to the previous period iii. Each period has a start and end iv. The following period has the same start as the previous end v. You can have four periods per day vi. Select the temp, one of high, medium or low (each as previously set). The selection is helpfully illustrated by tiny 'sun, dot and moon' symbols (meaning high, med, low respectively). v. Save using Select RUN 8. Now use Mode to set it to automatic to run the program. Mode can also be used to set it to economy (a low setting), manual (high setting) or MOUNT / UNMOUNT to safely remove or put it back on the valve - quite useful if you want to program without doing Yoga. PARAMETER SETTINGS There are 13 parameters such as language, rotation and most usefully, ROOM TEMP (as noted by another reviewer). Room temp means the device shows the actual air temp and not the current set point. It can be set by pressing Menu for five seconds, navigating to parameter 8, setting it to 1 (from 0) and saving it using Select. Parameter 12 can be used to calibrate the room temp (apparently, I didn't try it) The full list of parameters is on support.resideo.com - search for HR27 for this and other helpful downloads. I hope that when the batteries go flat I don't have to learn to program it again! But that's why I wrote these notes for myself. Or if I buy another, which I may very well do as it is fundamentally a good product - let down by poor documentation.

Easy to fit and work well. Instructions are fine if you follow carefully. These are programmable (time and temperature) rather than smart. I'm using them alongside connected/smart thermostats for some of the radiators, especially where I had two smart valves on different radiators in the same room which were fighting each other.

The items may or may not work, so I won't give this a 1 star review, but the lack of any clear set-up instructions (either in the box, or on line) renders the question almost academic. It's just so complicated and unclear that it simply isn't worth the effort or frustration of wasting several hours trying to fathom out how to set them up, which is what we've done. Unfortunately I'm beyond the return date, so the items will end up either being given away to someone more capable than us, or thrown away. I know from other experience that there are alternative solutions out there which work in a much more straightforward fashion and with proper instructions at modest additional cost. Unfortunately, these items have been a waste of money and time, from my perspective at least.

50 euros for a product thats impossible to mount no matter what adapter I used I couldn't get it right. And I have checked whether my heater was the right one. Their videos are no help and the adapters that are given are simply useless. Bought this to save money, ultimately I was left with 3 hours of wasted time.

Ottimi, silenziosi, facili da installare.

Sur le lot de 2 x 2 têtes, un colis livré sans pile. Le raccord Acova semble être compatible, de même diamètre donc dans un premier temps, j'ai essayé de visser la tête dessus. Impossible, pas plus de 2 tours. Je n'ai pas forcé car l'écrou de la tête est en plastique ( bof en passant). J'ai donc utilisé l'adaptateur adéquat et franchement c'est pas si simple à installer ! La tête saute soit du pas de vis de l'adaptateur soit c'est l'adaptateur qui saute avec la tête. Après plusieurs essais, j'ai trouvé une méthode de montage qui semble fonctionner. Il faut visser la tête sur l'adaptateur puis serrer mais pas trop l'adaptateur sur le raccord. Sinon la tête risque de sauter en abiment le filetage de l'adaptateur. Bon courage.

Der Heizungsregler ist gut gestaltet und besitzt alle Funktionen die ich erwartet habe. Was zu beachten ist: die Zeiteinstellungen für die Tages- und oder Wochenprogramme müssen durchgängig korrekt eingestellt werden. Ansonsten stimmen die Auf und Zu Zeiten nicht.

El termostato tiene muy buena pinta, pero no conseguí montarlo en mi radiador, la métrica y la profundidad eran distintas y no encajaba ni con adaptadores
