With LPB-capable devices, the basic unit with LPB device address = 1 can provide the
function of Central optg mode changeover. Then, the changeover actions on the central
basic unit (via Hx) or parameter HC optg mode changeover) also act on the heating
circuits and DHW of the other basic units on the LPB.
The effect of switched on and activated central operating mode changeover depends
on the type of unit used:
With devices of version 1, the heating circuits change to Protection mode.
With devices of version 2, the heating circuits change to a selectable operating mode
(Protection or Reduced). The operating mode can be defined for each heating circuit
(parameter Optg mode changeover (e.g. (900) for heating circuit 1).
Note!
With all devices, local selection of the operating mode is disabled during active
central operating mode changeover.
The scope of operating mode changeover via input H is as follows:
Locally
Local action: The local heating circuit is switched on and off.
Centrally
Central action: Depending on the setting made on Summer/winter heating limit (730),
either the heating circuits in the segment or those of the entire system are switched on
and off.
