The Niko Home Control Connected Control Unit (550-00004) is the central module for every Niko Home Control 1.x installation. It manages the system logic, powers the bus, connects IP equipment (such as touchscreens and video door stations), and enables remote control via smartphone or tablet. Each installation requires exactly one connected control unit.
Product description
The module is designed for DIN rail mounting and serves as the gateway between your home network and the Niko Home Control system. It features a WAN port for internet connectivity and three RJ45 ports for the internal Niko Home Control network.
Installation and wiring
The unit must be installed on a DIN rail. The wiring configuration is as follows:
- WAN Port: Connect this port to your home network router. The router will assign an IP address to the control unit, enabling communication with Niko Home Control software and remote access.
- RJ45 Ports: Use the three available RJ45 ports to connect IP equipment, such as touchscreens, video door stations, or Ethernet switches that group these devices.
- Power Supply: The unit requires a 230 Vac, 50 Hz power supply.
- Bus Connection: The unit powers the bus, modules, and controls. It includes automatic terminals on the top for connecting to the rail coupler and on the bottom for 230 Vac power.
