6.5.37 Operating mode changeover via input H

The heating circuit can be forced to adopt a selectable operating mode via input H by
actuating a contact. The operating mode required when changeover takes place can be
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.

Note!
A basic unit with LPB device address = 1 can provide the function of central operating
mode changeover. In that case, changeover on the central basic unit (via input H)
also acts on the heating circuits and on DHW heating of the other basic units
connected to LPB.
