Danfoss LC-13 e1 error code

Hi all

One of my Danfoss LC-13 valves is displaying the e1 error code. As far as I can tell, it is a transmitter error. I teied to exclude it, but couldn’t. I have factory reset it, and deleted it in the HUB.

I can’t add it again though :confused:

All the other valves works as they should, and have done so for about a year.

What am I doing wrong?


Did you find out what went wrong?

I’m having the same issue. Keep getting E1 error and hub doesn’t seem be able to find the thermostats. (4 out of 9 having the same issue…)

I swear they worked fine before spring time…tried everything from repairing zwave to resetting the trv to factory mode. They are all ver 1.0 as with the other 5 that are working…

Can’t find it as a device on new app either…
