Energy Control Unit G4

Key Features & Benefits

  • 8 ENCELIUM® GreenBus II channel ports, 22.5VDC, Class II
  • Tenant LAN Access USB 2.0 Port
  • ENCELIUM Energy Control Network Port – Ethernet 1-/100BaseTx Cat. 5 RJ45 port
  • Configuration stored in non-volatile flash memory
  • USB 2.0 port on the front of the unit to restore or back up database from USB drive (should only be used with instruction from ENCELIUM personnel)
  • 8 channel communication status LEDs on the front of the unit

The fourth generation Energy Control Unit (ECU G4) is a rack or wall mounted control device that collects, processes, and distributes lighting control information to ENCELIUM control modules, wall controllers, and other devices over the ENCELIUM GreenBus II network.

Each ECU G4 features eight GreenBus II communication channels and typically controls 100 nodes per channel (8 x 100 = 800 nodes in total).

The ECU G4 is the central intelligence point in the system. It collects signal information from photo sensors (light levels), occupancy sensors (occupancy status) and wall mounted lighting controllers. It then determines appropriate brightness levels or ON/OFF status for each fixture and zone. Photo sensors do not directly control light levels but rather are connected to the ENCELIUM GreenBus II network and provide light level information to the ECU G4. The ECU G4 then determines what action to take based on the status signals from the sensors.

Each ECU G4 has one Ethernet and USB port for Network connections. The Ethernet port is for communication with other ECU G4s and the SSU on the ENCELIUM Network. The USB port (using a USB to Ethernet adapter) can be used for communication with a facility or tenant’s Local Area Network (LAN) to allow secure communication with ENCELIUM Equipment for access to the ENCELIUM Polaris 3D® or Personal Control Software (PCS) applications. ECU G4s are typically located in the electrical room or communication closet on each floor of a building and are connected to a network switch using standard Ethernet connections.
