defined for each heating circuit via the Optg mode changeover (900/1200/1500). In that
case, selection of the operating modes on the controller is disabled.
The contact type can be set.

A basic unit with LPB device address = 1 can provide the function of central operating

also acts on the heating circuits and on DHW heating of the other basic units
connected to LPB.
