Holidays/special days

For each room group, a specific holidays / special day program is available. This
program is firmly coupled to the relevant room group.
The plant operator can enter days deviating from the normal 7-day program as
holidays or special days via the "Holidays / special days".
Entry of holidays / special days is described in the Operating Instructions B3121.
As default, the holiday / special day program of room group 1 is defined as the
master, and all other holiday / special day programs as slaves. This means that the
settings apply to the entire RMB795B central control unit.
If independent holiday / special day programs are required, appropriate
communication settings must be made:
Autonomous (for a specific holiday / special day program of room group x)
or
Master in some other calendar zone (for a holiday / special day program that shall
also be used by other room groups)
Holiday / special day programs can be assigned to room groups or to other devices
on the bus.
Different sources can be used as the master. These can be entered on the
RMB795B central control unit.
The following settings can be made:
Autonomously: Does not send and does not receive
Slave: Receives holiday / special day program from the bus.
Master: Transmits the holidays / special day program via bus.
The impact of the individual settings is explained below:
