Building Technologies 15 Communication 2017-09-29
If a common holiday or special day program shall be used, holidays/special day
operation is to be defined on one of the controllers as the master and the other(s) as
the slave(s). This works analogously with the 4 internal calendars.
With master / slave operation, this setting is used to make the zone assignment. In that
case, the slave devices are given the same holidays/special day zone as the master.
It is possible to define several zones with one master per zone.

15.3 Room data
Every heating circuit belongs to a geographical zone. This zone symbolizes the room to
be controlled. Within the zone, all room-related data will be exchanged:
• Room operating mode
• Room temperature
• Setpoints
15.3.1 Communication variants
The requirements (operation, function) placed on the generation of the room operating
mode differ significantly, depending on the type of building and its usage. The
communication variants described below allow the determination of the room operating
mode to be adapted to the requirements.
Basic variant 1 assumes that a heating circuit has its own individual room operating
mode, independent of other plant (heating circuits, ventilation). This means that the
exchange of data is restricted to the heating circuit and the rooms in the relevant
geographical zone.
If there is a room unit in that zone, the heating circuit will automatically receive its room
temperature and setpoint readjustments. In addition, data are exchanged to determine
the room operating mode.
