Modular, programmable room automation stations for HVAC, lighting, and shading. BACnet / IP communications; BACnet profile AAC (BTL label). Optional island bus (including bus power supply) to connect TX-I/O modules with any data point mix. Optional KNX PL-Link peripheral bus (including bus power supply) to connect sensors, actors and room units.
Use PXC3 series room automation stations can be used for buildings with more sophisticated requirements on functionality and flexibility. Desigo Room Automation is used when several disciplines (HVAC, lighting, shading) are combined to form one solution and when high flexibility is required. Desigo Room Automation is perfect for solutions optimizing energy (class A) without loss of comfort. Functions Control of several rooms A PXC3 series room automation station can assume control for multiple rooms.
Communications · The room automation stations have a 2-port Ethernet switch to support for lowcost cabling via line topology. · A USB Device port is available for service and commissioning. · TX-I/O modules connected directly to the PXC3 allow for direct connection of field devices. This offers maximum flexibility. · The KNX PL-Link peripheral bus supports room operator units, sensors, and actuating devices.
Mechanical design The compact build allows for mounting the devices on a standard mounting rail.

Installation See planning manual Desigo Room automation, CM111043. STOP Island bus Polarity: If a TXS1.12F10 supply module is connected to output 24 V, do not invert ~ and ^. The devices are not damaged but island bus communications will not work. Note! Operation If island bus or USB communications do not work, this is an indicator that the AC 24 V operating voltage is incorrectly wired (conductors ~ and ⏊ inverted).
