The room control panel is a one box solution, fully wired and ready for installation. There are different control panel solutions on offer, sizable to centralised, distributed or hybrid controls. Cabling topology for centralised control requires all field 230V and control cables to be wired into the panel. Distributed controls have a minimal amount of wires into the panel and require the least panel space which reduces cabling cost substantially. Further, contraction and expansion of the system may have little impact on the size of the distributed panel. Through the RON bus communication, the Local Control Unit (LCU) is connected to output devices such as relays, dimmers and PWM/0-10Vdc analogue outputs. The control panel with its configurable application software, is a smart control system, suitable for hotels, homes, apartments and other residential or commercial buildings. It can operate as a stand-alone system or as part of a network of control cabinets using TCP/ IP communication protocol.
