Expected Installation Time
Removing the Old Display Module
1. Use a 1/16” hex key to turn the retaining screw
at the bottom of the sensor housing clockwise
until it is fully recessed.
Figure 2. Retaining Screw Location.
2. Use a No. 2 flat-blade screwdriver to gently pry
the sensor cover away from the mounting base
at the bottom, and rotate upwards until the
housing is separated from the base.
3. Disconnect sensor wiring by doing the following:
a. If the sensor is connected with an RJ-11
cable, carefully remove RJ-11 plug from the
back of the sensor.
b. If the sensor wiring is connected to a
terminal block, note the terminal locations
of each wire. It is advisable to take a
picture of the wiring for reference during the
re-assembly process. Then, carefully
remove the wires from the sensor terminal
block(s).
4. Remove the circuit board from the sensor
housing by gently prying above the two retaining
clips with the No. 2 flat-blade screwdriver.

5. After removing the circuit board assembly
from the housing, turn the housing over and
mark the display with the permanent marker.
This marking will be helpful in distinguishing
the new the new display from the old one.
6. Use your thumb and index finger to gently lift
the retaining device where the display ribbon
cable connects to the circuit board.
Figure 4. Ribbon Cable Attachment Point.
7. Gently remove the ribbon cable from the
receptacle on the terminal board.
8. Turn the circuit board over and use needle
nose pliers to loosen the display by carefully
squeezing the three attachment prongs
while gently pushing them toward the board
surface.
9. After the attachment prongs are loosened,
the display can be lifted from the board. Use
a flat-blade screwdriver to gently pry it loose.
Installing the New Display Module
Press the new display assembly into the circuit
board on the side opposite the RJ-11 port or
terminal blocks.
1. Insert the ribbon cable into the receptacle
and secure the retainer by gently pushing it
down on both sides.
2. Insert the circuit board into the front housing.
Ensure that the board is properly seated in
the retaining tabs.
3. Connect the RJ-11 cable or re-attach the
sensor wiring (see notes or pictures taken in
Removing the Old Display Module,
Step 3. a).
4. Install the sensor on the sensor base and
turn the retaining screw counterclockwise
until properly engaged with sensor housing.
5. To maximize the life of the OLED, it is
recommended that the screen saver
functionality be enabled at the sensor. For
details, see one of the following HMI guides:
For sensors with an RJ-11 port, see
Room Unit for TEC, and ATEC Operator
Interface Guide (125-703).
For sensors without an RJ-11 port, see
Series 2200/2300 Room Units for
Primary Equipment Controllers Operator
Interface Guide (125-706).
The installation is now complete.
