Used Danfoss wireless room stat and receiver , in working order , room stat shows connection loss but still works perfectly fine , I don’t know much about it or how to reset it , no returns!
I bought this to replace the existing Danfoss thermostat and receiver which was two years old.
It was very easy to install, I did not touch the hard wired parts , just took off the old receiver and put the new one on. The thermostat was a straightforward swap. 10/10
