Introduction
The Boiler Control 284 can communicate with a Building Automation System (BAS) using either BACnet
®
IP or Modbus
®
.
This manual provides information about boiler plant & system parameters that can be accessed by building automation or
management systems that use BACnet
®
IP or Modbus
®
communication. The 284 can be configured to provide monitoring
access or read / write access with optional target temperature control from the connected BAS.

Switch
Use a top or back knock-out to bring a CAT-5E or CAT-6 wire into
the wiring chamber. Connect the 284 to the BACnet
®
network switch
using the RJ45 port on the top edge of the control board.
Cable length must not exceed 150 ft. (45.7 m) for CAT-5E or
300 ft. (91.4 m) for CAT-6.
If the cable was manually made, check continuity across each
of the wires.

Troubleshooting
If there is no communication, check the following:
Check the ethernet cable. Cable length must not exceed 150 ft. (45.7 m) for CAT-5E or 300 ft. (91.4 m) for CAT-6.
If the cable was manually made, check continuity across each of the wires.
If there is intermittent communication, check the following:
Check the ethernet cable. Cable length must not exceed 150 ft. (45.7 m) for CAT-5E or 300 ft. (91.4 m) for CAT-6.

Troubleshooting
If there is no communication, check the following:
Check that the polarity on the Modbus
®
A & B terminals
is correct.
Check that Modbus
®
GND terminal is securely
connected.
Check that the Baud Rate on both devices are the
same.
•
•
•
If the communication is intermittent, check the
following:
Check that the communication cable is of the twisted
pair type.
Reliable communication depends on the cable length &
Baud rate used. Long cable length may require a lower
Baud Rate.
