Pairing a Sensor to a Wireless
BACnet FF (TB3026B-W Only)
BACnet FFs and sensors ship unpaired, verified by two
dashes in the Sensor Status field on the BACnet FF’s
Wireless Sensor Setup screen. To pair them, issue a pairing
command from the BACnet FF and then activate the
sensor.
Accessed from Field Service Mode (See “Field Service
Mode” on page 7), the BACnet FF’s Wireless Sensor Setup
Mode includes diagnostic screens for configuration and
checkout of associated sensors. With :UC displayed in
Field Service Mode, press the blank key (blank area) just to
the left of the blank center key, and then press the down
arrow key next to the :UC parameter.
Door/window sensors may be paired to any available
sensor number in the range 1-8. When cycling through
sensor numbers on the Wireless Sensor Setup screen,
unpaired sensor numbers show a status of --.
PIR sensors may be paired to any available sensor number
in the range 1-3.

TO PAIR A SENSOR TO A BACNET FF
1.
Make sure the battery is installed and activated in
the sensor.
2.
If the sensor is a door/window switch, align the mag-
net so that the sensor is in the closed position. If the
sensor is a PIR sensor, cover the PIR.
IMPORTANT
Verify that the sliding door/window contact is
closed and cover all other PIRs to prevent interfer-
ence during the pairing process.
3.
On the BACnet FF select the sensor to pair and then
press Reset. The RESET key disappears and WAIT is
displayed indicating that the BACnet FF is waiting to
pair the sensor with the next device that receives a
radio signal.
4.
Activate the sensor to be paired.
NOTE:
Pairing times out after 10 seconds of no
pairing activity.
5.
Verify that the BACnet FF and sensor successfully
paired.
Paired = sensor status is displayed, replacing --.
Timed out = RESET is displayed and sensor status
is --.

status.
TO ERASE SENSOR-TO-BACNET FF PAIRINGS
1.
While viewing any sensor status screen while pairing
is not taking place, press the blank key to the left of
CANCEL.
2.
Press the blank key to the right of DONE.
The sensor status field displays --, indicating
unpaired.
FIELD SERVICE MODE
Fixed Field Service Codes
Field service mode enables technicians to query and
command key operating variables in the BACnet FF while
at the BACnet FF touchscreen. A technician presses a
particular key sequence at the BACnet FF to enter field
service mode. In field service mode a technician uses the
left arrows to scroll through data codes and the right
arrows to change the value associated with a code.
The lower left of the LCD shows the two-digit data code
and the main area displays the data value. A pre-defined
list of data codes is available within the description of
each application. See BACnet Fixed Function Thermostat
System Engineering Guide (31-00098) for the complete
list of setup codes.
Users can be denied access to field service mode by
setting BV-68 to ON. A PIN code can also be required to
enter field service mode by setting AV-132 to the desired
PIN number.
Field service mode ends automatically if there is no key
activity for five minutes.
Setting Field Service Codes
To set field service codes
1.
From the home screen, press SYSTEM. Five blank
touch keys will appear at the bottom of the screen.
2.
Press and hold the center bottom key for approxi-
mately five seconds (see Fig. 11).
