hi,
i have a heating control a siemens rde20.1 and have no idea how to work it, the plumber took the booklet of user instuctions over a year ago and even after repeated requests has not returned it. I have tried looking on the net and had no look any help would be greatly received as we are either boiling or freezing.
thanks
