Have moved into a house with an (old?) Sime DHW / CH boiler and no manual, so I don't know how it works. There are two switches on the bottom LHS and next to these two rotating dials with no graduations. I guess the switches are for on/frost protection and the dials for DHW / CH. Which way to turn, and which is which, though? I get hot water but luke warm rads. The is no manual on the SIME website (www.sime.it) as it's an old model. Does anyone know how to work the settings or where I can find a manual.
Many thanks
