Useless controller ,no customer support
The previous controler lasted 30 years without a problem,plumber fitted new one RWB27 Siemens which is totally unclear and difficult to use, we are sitting here on a beautiful day with the heating on full and no way to switch it off.There is no OFF switch!!!I do not want to have to reset 14 On /OFF times everytime the sun comes out or we have a cold snap.Customer Services is a joke;recorded message saying read the manual.Someting as simple as a time switch should have intuitive controls with a logical menu.
