About this task
ZEC controllers are master devices on BACnet® MS/TP (Sensor or Zone) Buses. Before operating field controllers on a bus, you must set a valid and unique device address for each controller on the bus.
You set a field controller’s device address by setting the positions of the switches on the Device Address DIP switch block at the top of the controller. Device addresses 4 through 127 are the valid addresses for the ZEC controller.
Note: ZEC controllers ship with all address switches set to ON. Set a valid and unique device address on the field controller before applying power to the controller on the bus.
The DIP switch block has eight switches numbered 128, 64, 32, 16, 8, 4, 2, and 1.
