danfoss living connect not functioning

Other Devices & Integrations Climate Control & Temperature Sensors

Hi all ,

My danfoss living connect is not functioning properly.
It recieves its setpoint from vera , I can see it on the display ( although the danfoss keeps being in panic mode) , but the thermostat does not change the valve. Untill I remove power and add power again. But it stops again after some time.

Anyone has an idea? It is wierd that it recieves it’s instrucuon from vera, displays it , but doesn’t do anything with it.

Thanks,
Cor

Which version of the Danfoss TRV do you have? Only the LC13 version operates properly wit Vera (or other controllers)

The LC13 will adjust its valve immedialtely, and should not go into panic mode either

How to find out which version I have?

Thanks,
Cor

There is a sheet under the lid. but the best way is in “variables” under version.

@ Svaleb: it says the manufacturer , but model is empty , see attached screenshot.

This is correct.
Under “version” the last digits is 2.51, this is danfoss firmware version.

7

and is this the LC13?

8

No, it is one of the earlier versions.
It works in z-wave. but sometimes it loses contact with the controller and goes into “panic”, flashing network and bell icon.
Sometimes it will use battery real fast.
They work, but my girlfriend did not like them, she came home to a cold house…so…

I have 2 of these and they worked about 99% of the time , So i couldn’t really complain , except for the battery life.

So what I did , I bought two 3V DC power adapters and use those instead of the 2 AA batteries.

It looks that since than i have more issues than before , the only other thing I did was change the wake up to 240 seconds.

It doesn’t make sense to me that 2x1,5V battery is any difference than 3V DC by a adapter.

Any thoughts,
Thanks,
Cor

That is very often.
I just checked mine, it seems ui7 have set them differently ??
I set wake up to 18oo and poll to 900.
As far as I remember the settings in ui5 was almost half an hour and some 20min poll.

I was annoyed that when I set another temperature , it took so long to react . Also teh amount of batteries the device wanted… :frowning:
So , my solution was , feed the danfoss thermostate with a 3V adapter. So I can do a wake up every couple of minutes, no worries about batteries and frequent updates.

@cor
I have had 10 Danfoss in various versions.
As mentioned before I had to get rid of them.
Now I have one, the latest model, and it works well. 1,5 year on battery, that is ok.
I have recently received a new to test “Comet heating thermostat”. It works but it seems it is not fully implemented in vera.
I think I have an overview of danfoss versions somewhere it might be useful to you, I will try to find it.
Are you from US or EU.

@ Svaleb: Thanks a lot!

1,5 years , that is Ok, although I have now 3V DC near my radiators and all neatly behind the walls…

I will do some more tests next week when I am home , but I am seriously thinking of trowing them away and get for example the stella_z thermostats.

Anything You suggest I can do with the danfoss for troubleshooting?

EU By the way,

Well, it helped to take out a battery for a sek. when it goes into “panic” in your case switch the power.
Make sure they are NOT left in installation mode.
It is also possible to make them find the net in the LI function.
But they are unreliable, today there is a better version, Danfoss should have offered some kind of “deal”.
I have heard that if you are clever enough you can make them work in other systems, homeseer (i think).

Now I dont know were you live, but there is some European models.
I am trying “comet” but it is not fully supported by vera, yet.
I have thought about Stellar, but it is unclear to me if it is possible to change the temperature by hand on the device itself, or it can only be changed through z-wave.

I understand the stella , you can only change the setpoint via z-wave , which is not ideal offcourse , but if it respons properly.

I allredy tried several times removing power , than the device goes to 21 degrees , responds quite Ok , but next day it is the same again.
Someweher I read , the panic mode happends due to many changes (in set point?) … maybe changing the wakeup time will improve the reliability , although … quicker response would be better.

Do you have some info about Comet.?
The new danfoss , are the more reliable , or can can I consider them Good and Reliable? since I like the look of them.

Here is some info.
And I opened a tread in the forum too.
I have only 2 weeks experience and have had one “cant detect device” but who has not had some of these lately.
I can set temp., works ok. But modes seems not to be supported by vera. I wrote to them, but they are of cause quite busy now.
It will change modes if I wake it up right after sending the command, but vera does not store the command until the device wake up.

I have tried a variety of devices, Danfoss LC13 and LC12, and StellaZ. The LC12s go o to panic mode but the LC13s so far have performed very well (Vers3, UI5). The StellaZ go into failure mode from time to time (once every 4-6 weeks), they become unresponsive and report 0 degrees temperature. Reset requires a power cycle followed by a “configure now”. I also found the build of the StellaZ to be problematic, they tend to partly pop off the mounting ring.

At this time I am thinking about replacing my remaining TRVs with Danfoss LC13, this seems to be the most reliable option now. There apparently is a new brand on the market but I have not had my hands on those yet.

I have LC12’s, and they burn through a set of batteries every 2 to 3 months, which is in no way close to the 2 years of battery life that the tech specs promise. So I escalated to both my supplier and Danfoss. To be honest I am appalled by the lack of commitment to their product. The short version is that they claim to be ZWave certified and that therefor these battery issues are my problem. That the devices constantly end up in panic mode and drain their batteries is completely lost on them.

My supplier couldn’t work out a deal with them, so he offered me a 10% discount, which is quite disappointing if you have to replace 6 valves at 50 euro’s each…

I had some talks with danfoss too.
Danfoss was not “polite” and they did not know what they were talking about.
They dont want to listen to a “nobody” I was told.

Hi, a bit late maybe but I have used both Stellaz and Danfoss, all versions. My Stellaz are now on the shelf, too much funny behaviour, in addition if you run them on an adapter they don’t recover after a power outage, the Danfoss works ok. The only issue with the Danfoss is that you need to set the Vera to use firmware 2.78 to make the older versions work (see instructions on Vesternet). If you do they work fine, battery 1 year plus and no panics. I’m still on UI 5 moving now probably to Homeseer since Vera messed up with the UI 7.
