Nice video, but I think swappable batteries are great, if you don't want to throw then away use rechargeable ones and you don't have to throw the entire unit away when the internal batteries are dead
Not sure about that. Rechargeable batteries provide 1.2V instead of 1.5V, and I have seen comments in the discussion that it does not work well with them. :-(
Low self discharge NiMH batteries work well - such as the Eneloop 5th generation. They need changing slightly more often than disposable batteries but in the long run saves money and better for the environment.
I already successfully had an EVO home system installed on the Nefit heating system ( HRC 45 ), but I would like to connect the hot water boiler ( combi with Nefit kettle) to the EVO home. No body seems to know what we need and how to connect. On the screen of the EVO home controller on the page 'System Summary' the first item is Boiler Control..... Wireless Relay Box. Can you advise us please.
In what way do the thermostatic radiatorbuttons (HR90/HR92) get influenced by the heat of the radiator itself ? Aren't they too close and does the way they are installed matter ? E.g. in the same direction as the radiator or perpendicular to it ?
Apparently testing has shown that they do detect a good representation of room temperature despite being close to the radiator. There is the option to have separate wall mounted temperature sensors in each room. This adds to the cost, and in most cases isn’t necessary. I’ve had that in one room where that radiator is behind furniture - so a wall mounted temperature sensor is more representative. If the radiator and sensor aren’t obstructed by furniture it works well without the wall unit.
Vraagje. Wat gebeurd er als ik maar 1 ruimte wil opwarmen? Valt dan niet mijn ketel op storing omdat hij zijn warmte te snel terug krijgt? Mijn ketel werkt gewoon met een aan/uit contact.
I was looking into these last year. But the lack of integration with Android Home or Apple's Home kit had me worried. Is it all proprietary? Have they made progress in this end? I don't want to be dependant on Honeywell's software forever.
Found a comment from Honeywell somewhere: "Currently we are not working on an Evohome update, that works with Apple Home Kit. That would require massive Hardware changes." Don´t know where I read it.
Very nice video, man! Thank you. I will probably buy it. And I like your comment about the batteries - you have described my thought as well. I might consider adding a wire with 3 V from an adapter. I will see. Also nowadays, we in Europe have even another motivation. My flat, for instance, is on a building estate heated 100% by gas ... About 90 % of it is Russian gas, and we in the EU are nowadays practically financing Putin's war in Ukraine :-! Each piece of the saved gas thus matters.
Yes and no. To make it work well you should. It destroys the benefits of this system if you don't. But if you have a radiator half open it will work too. However it will mean you heat up you living room while another room is asking for heat. So waisting energy
@@cosminparpauti3723 If you refer to the tablet yes it has an internal thermostat which is nice because you most likely use it in the (middle of) the living room which is often the room with more then one radiator.
Hans Keesom tks for your answer. In my ling room i have underfloor heating and at top floor i have 3 bedrooms with radiators. In this case can use tablet vor controling temperature in living and HR 92 for bedrooms?
@@cosminparpauti3723 Tablet measures the temperature. To control it, it needs to connect to a controller for your underfloor heating. Not sure which controller that is as I don't have underfloor heating. Yes hr92 for bedroom radiators. You will save a lot of energy by programming the bedrooms at 12 degrees celsius 24/7 and having the users of bedroom manually turn things up (blocked at 21 degrees) manually when needed. Make sure to programm a number of moments that the programma will turn it down again to 12 degrees, like the time they normally wake-up on a schoolday.
Is it compatible with any radiator type/brand? If 12 is the limit of controllable vales, can't you just close the valves totally in the extra rooms and open them when necessary? How does the 5v relé is installed?
System works best with all valves controlled with these heads, as the other rads would no longer have anything to trigger them without these heads and therefore there are only on when there other are, You have to have TRV valves installed and they have multiple heads to fit the different types.
All three radiators can be in the one zone, each with an HR92 controlling the valves. The HR92s will be all bound as actuators for the zone. However, only one of them will be bound as the temperature sensor for the zone. The other option is to bind one of the wall mounted stats or the evohome controller as the sensor if it is staying in the room and the three motorized heads on the radiators will be actuators only for the zone. This is a configuration that is typically employed in large rooms with multiple radiators.
There now is a webinterface so ypu can program the Evohome from your pc.
So happy there is actually a more up to date review of the system. Most things are from 2010-2015.. Bedankt

and you want to use these valves for much longer then batteries last.

How did you flip the display so it is the correct way up when the valve is in that position?

I use Lifepo4 AA battery on mine (with one being a connector). Great video.

How does the device communicate with boiler? is it via the relay?

hangt er van af hoe snel die ruimte op warmt denk ik

I agree with you. Though they work with the OpenTherm protocol and with some fiddling you can get it to work with IFTTT.

Do you need those digital valves also on your radiators in the living room (where is your base thermostat?)
Yes and no. To make it work well you should. It destroys the benefits of this system if you don't.
But if you have a radiator half open it will work too. However it will mean you heat up you living room while another room is asking for heat. So waisting energy
@@HansKeesom Pls tell me if the base thermostat have temperature senzor.

12 is the number of zones. You can have multiple valves in one zone.

Interesting thing.
Thanks for review
What is The loweast temperature you Can set it
If you have three radiators in one room can you program all three TRVs to one Zone ??
Yes

However, only one of them will be bound as the temperature sensor for the zone.

Can't you use IFTTT to control the unit remotely?
+Lukasz Szelag ifttt was just added to the lyric, I think it'll come to evohome soon
Where did you by it?
+moscomau I didn't
It turns out that simply subscribing isn't enough, please click the bell thingy too. Thank you.
The mobile app was last updated a year ago, not a good sign...
Why is that, They made a good app a bit better.
an ordinary thermostat would do just as well? Understatement of the day lol
The bezel on that thing is ugly
