value. Enter an alternate value by using the numeric
keys and press ENTER to output the new value or
press ENTER to move to the next channel.
This menu will only allow you to modify the output
signals that are connected to the system, therfore
A03 - A06 may not be modified unless the cor-
responding output cards are attached to the system.

3.22.10 When the controller is setup to communicate with the
building automation, press the INFO/8 key while at
the test selection screen, to test the RS communica-
tion. The display will show:
Test Communication
B&G Read #
B&G Write #
If the controller is communicating properly, the num-
bers will continue increasing in value. For Modbus
protocol the read and write numbers will be equal,
BACnet and Johnson N2 protocol the numbers will
not be equal. If the numbers are not increasing in
value then the controller is not communicating prop-
erly. If it is not communicating, check the wiring at
the terminal blocks and the RS communication card
mounted on the controller.
3.23 DEFAULT SETUP
3.23.1 In the event the user would like to change all of the
setup variables back to the default values the default
setup menu will complete the task. The default values
are defined in the tables included in Sections 3.7 to
3.18. In addition all sensor and pump setup informa-
tion will be erased.
Prior to completing the default setup it is strongly
recommended that all factory/field variables be
recorded for future reference. Use the “Field Value”
location in the tables shown in Sections 3.7 - 3.18 to
record your current data. Also record your sensor
and pump setup information on the wiring diagram
that was included with the unit.
