BACnet ARC156
To set up the Fan Coil for BACnet ARC156
1 Turn off the power for the Fan Coil by disconnecting power terminals.
2 Using the rotary switches, set a unique address. Set the Tens (10's) switch to the tens digit of the address,
and set the Ones (1's) switch to the ones digit.
EXAMPLE If the controller’s address is 25, point the arrow on the Tens (10's) switch to 2 and the arrow on
the Ones (1's) switch to 5.
NOTE The Fan Coil recognizes its address only after power has been cycled.
3 Set communications selector for BACnet ARC156.
4 Set the both DIP switches 3 and 4 OFF for BACnet ARC156.
NOTE The baud rate for BACnet ARC156 is automatically 156 kbps, so DIP switches 1 and 2 are overridden.
5 Connect the communications wiring to the Comm port in the screw terminals labeled Net +, Net -, and Shield.
