● Desigo PXC00-E.D for monitoring Desigo room automation stations.
● Desigo DXR2.E18/PXC3.E.. for central functions within the floor scope.
● Desigo DXR2.E../PXC3.E.. for room and room segments / HVAC, lighting, and blinds.
You can operate with cascading group master functions if lighting and blinds exceed a maximum of 500
commandable group members. This could, for example, be used for emergency control of blinds actuators
over multiple facades over lighting over multiple floors.
Notes on project implementation
In the project example above was generously planned (since it is a midsized to large project) and one
PXC00-E.D was assigned to each floor scope as well. It assumes monitoring of Desigo room automation
stations. The PXC00-E.D in the building scope is used for scheduling and superposed functions for various
floors as well as central functions for room operating mode, lighting, and blinds.
Depending on building design, air handling may be decentralized on various floors. A PXC100-E.D each is
used in the floor scope to this end. It takes over scheduling and superposed functions for the floor / floor
scope. The PXC00-E.D monitoring unit is used in the building scope to monitor Desigo room automation
stations.
