Planning 1:
Implement HVAC plant
concept
Planning 2:
Organize
communication
Engineer bus network
Siemens
Building Technologies
Steps required to implement the HVAC plant concept for the RMB795B central
control unit:
step Procedure
1 Decide on the device types, their
number and application
2 Define device installation
3 RXB/RXL room controller and Synco
room thermostats RDG/RDF/RDU
combined into room groups
4 Enter the devices on the floor plan
Organization of communication on the KNX bus is subdivided as follows:
• Engineer bus network
• Complete the "Synco
(C3127)"
And these are the individual steps to be followed:
step Procedure
1 Topology:
Define area, backbone and line, define the
device addresses
2 Define the type of bus power supply
3 Define the required system components
4 Check limitations
5 Design the network structure and
connection diagrams
6 Create the cable lists
7 Transfer the topology and the physical
device addresses [1...254] to the floor
plan

concept given on the floor plans
Including addressing of the
room group and the
geographical zone address

Notes
Depending on:
Number of devices, network
extension, embedding
Size, central, decentralize
Line couplers, bus power
supply, etc.
Number of bus users per
line, network extension, bus
power supply
Define cable routing and
cable lengths
