KNX Room Control Unit for Smart hotels
KNX Room Control Unit

Relay Description:
① R1–R4: 10A; R5–R18: 5A
② R6, R7, R8, R9, and R10 correspond respectively to the fan coil unit functions: Fan Speed 1, Fan Speed 2, Fan Speed 3, Heating, and Cooling.
③ R11–R18 correspond to the curtain control outputs as follows:
• R11 / R12: Curtain 1 Up / Down
• R13 / R14: Curtain 2 Up / Down
• R15 / R16: Curtain 3 Up / Down
Note:The dry contact input and output terminalsequences are reversed.For example,the inputterminal sequence is 7-1,COM,while the outputterminal sequence is 1-7,COM.
The hardware includes:
- 4×10A relay channels
- 14×5A relay channels
- 21×dry contact input channels
- 21×dry contact output channels
- 4×0-10V channels/1×DALI channel(0-10V and DALI are mutually exclusive;only one can be selected)
- 1×IR interface
- 1×RS485 interface
- 1×KNX interface
- 1×100 Mbps Ethermet port
- Built-in 24V/2A auxiliary power supply
- Built-in 320mA standard KNX power supply
- Built-in 1-channelDALI power supply
- Built-in standard KNX IP gateway
Function:
- Fan Coil Unit (FCU) Control
- Curtain Control: Supports 4 curtain channels
- Switching Module: Supports configuration of up to 18 relay outputs Dry Contact Control: Supports 21 dry contact inputs and 21 passive dry contact outputs; output voltage: 22–24V
- 0–10V: Dimming control module providing 0–10V control signals, with 4 output channels
- DALI: 1 channel
- Infrared (IR) Module
- RS485 Integration
- Smart Speaker Integration
As a KNX room control unit supplier, The Room Controllers Unit(RCU) is integrated KNX-basedroom automation controllers designed for centralizedcontrol of multiple room functions.Depending on theconfiguration,they combine fan coil control,lightingswitching and dimming,curtain control,drycontact I/O,0-10V or DALI lighting control,infrared control,RS485 integration,and smartspeaker integration in a single device.With built-inKNX power supply,DALI power supply,auxiliary24V powersupply,KNX IP gateway,and Ethernetinterface,the controller reduces the need for multipleseparate modules and is well suited for integratedroom automation applications such as hotels,apartments,offices,and other smart building projects.
