I have an RF3 wireless roomstat and associated receiver on the CH system.
This worked Ok last year, however not been used until now. Needed new batteries it seemed, duely changed.
I have all the instructions but cannot get the reciever into 'learn' mode to pick up the thermostats signal.
I did power it all down for an hour or so, and it was fine as it didnt need to learn (default settings), but overnight the signal was lost again.
What now?
