just use a pencil and a stopwatch ;D
tape them togetherwith the point on the stop of the watch and press set when you give the command in vera. when the actuator moves, it presses the stop and you have your timedelay 8)
Just kidding, but it can be hard to see when the valve shuts…
They should not need to be installed to test them,
It would be great to have them both side by side to witness the reaction time for it to go simply from full open (30c) to full close (5c) - that would be good.
I don’t have any of the Danfoss thermostats but am hoping to buy and so have been following the various discussions as well as reading the documentation.
The reported 1.5hr delay seems very strange: The device has an open door/window function – I wonder if that is being triggered if you download a new set-point that is a more than couple of degrees above its actual measurement? I have not come across a description with the details of what temp differential or slope trips the open window mode which shuts the valve. When you press the ‘up’ button it ‘knows’ it’s a manual adjustment and hence drives the actuator. But if the firmware is weak in the implementation it may just be setting a flag when there is a certain differential between the set-point and actual and then waits to decide if it’s a temporary change (open door) or not.
Perhaps some users could experiment with ramping up (rather than a step change) the set-point from the actual to a higher desired value to see if this has any impact on the response. As it uses a PID algorithim you would expect it to incrementally change the actuator rather than one step change.
Selecting the ‘Undersized’ radiator mode might also prompt more frequent adjustments?
Has anyone else purchased one of these ‘new’ valves ?
I’m still very curious to hear how they might have changed…
I have heard from a heating installer (heating broke down last week:S) that Danfoss has stopped production of their own kranes and link system since they had the same problem and could not fix it to work properly with their controller.
It seems they have give up that part of the market, lets hope they still continue with the zwave units…
Hi
I have got 12 Danfoss Living Connect version 2.50z. I have had them for 5 weeks now, and they are working fine. New setpoint are recieved within 15 min after being sent and the termostats are changing slowly within one hour after recieving setpoint, unless the are activated manually.
Prior i had 11 DLC in an older version, they didnt work well.

@moni - so based on your opinion the new Connect Z are performing better than the previous version?
Hi
I also got 12 of them about a month ago (014G0012). As far as I can tell they work very well. I log room temperatures using 433 MHz temp. Sensors. There I can see how the temperature starts to drop or increase almost immediately after a scheduled change. The only delay I see is the 15 minute wakeup interval they are set at by the Vera.
I have both thermostats, 014G0001 and 014G0012, they are working both fine. I’ve set wakeup time from my Vera Lite to 300 seconds and valve starts to adjust 5 minutes after setting new set point. Delay still exists, because Danfoss adjusts its new setting slowly, but if I set new setpoint higher than usual, for example 22C → 28C then it adjusts fast.
One of my 014G0012 just died so I had to send it to Danfoss to inspect it. They sais that they will replace it, but lets see what happens, because Danfoss Finland doesn’t support those.
@parkerc. My previus version was 1.06 in Firmware. My new thermostats with version 2.50z are much more reliable.
Moni - quick clarification question 
- are your others fw 1.06 or fw 2.06 ?
@parkerc. All my thermostats where 1.06. All are now 2.50z.
They really said the software has not changed so I really curious whats going on here…
I think it’s all down to personal interpretation, as @moni talks about having fw1.06, where as many of us have fw2.06 . So the jumpt from fw 1.06 to fw2.50 could be much more visible. (Unless I’ve misunderstood something?)
Okey… Im going to be a complete n00b here but ive just tested one of my units here. Its an 14G0009 with the 2.06 fw on it.
I removed the untit and set it on 26 deg.
I felt the unit move and held it with my finger in the unit (so I could feel the movement).
With my mobile phone I set it at 6 deg and ticked a stopwatch.
This way, it would take upto 15 minutes or rediculously long basically.
Within 10 minutes it moved…
I really dont get it anymore… how do you guys test this, Im feeling a bit of a idiot here…
Hi Druw,
I known what you mean, although i think there are a lot of factors at play here .
Looking at your test, The danfoss valve has its own temperature sensor, so by removing it you’ve already changed that element , plus when you hold it, your hand/finger is probably influencing it even more.
I would also add that the quality of the metal value on the radiator itself could influence the timing too, any rust or friction on its movement could play apart too. So macro turns might contribute to the pin sticking more
For any test to be valid I guess it would need identical conditions and steps taken with both versions of the LC
All I can say is that I and other have seen a long delay, I now hardly ever change the set point value, so it seems less of an issue, but others do look to do large scale temp change requests (to simulate off to on)
I agree that there are a lot of variables to consider but the issue was that the valve does not respond for 1.5 hour which it does…
aside from the variables the thing works directly (as soon as it wakes up) and offcourse it had the controller softare which opens/closes it gradually but it responds the same as connected to the radiator as far as I can tell…
Which software do you guys have (fw & vera) and do you have issues? (lets make a small list to see if this is typical)
Danfoss: 2.06 / Vera 3: 1.5.459 : no issues
Danfoss 2.06 / Vera Lite 1.5.408 : no issues
Danfoss 2.50z / Vera Lite 1.5.408 : no issues
Danfoss 2.06 / Vera Lite 1.5.408 : no issues
Danfoss 2.50z / Vera Lite 1.5.408 : no issues[/quote]
I have now tested the Danfoss Living Connect Z for a month or so without any issues.
Danfoss fw 2.5.3/Vera Lite 1.5.408
Very interesting thread. Thanks for researching all this.
However, now I am stuck with 6 Danfoss LC version 1.06 ones that basically never functioned correctly (I am talking the 2 hours delay).
Anyone know of a way to upgrade the firmware in those devices?
