Components
The factory-installed display in the electrical control compartment allows complete
access to unit test features, schedules, discharge air setpoints, fan control, alarms,
and other unit operational setpoints. Option RB5 is a second, remote-mounted display
that can be eld-installed up to 656 ft (200M) from the unit allowing the same unit
access. NOTE: If the remote display needs to be mounted more than 656 ft (200M)
from the unit, contact the factory about adding a eld-supplied power supply required
to extend the range up to 1500 ft (457M).

b) In the electrical compartment, nd the unit display and the main controller below
it (see illustration on page 1). At the main controller, locate and unplug the 6-pin
connection cable (the cable that connects from the unit display to the controller).
Move the disconnected end of the cable to the module installed in Step 2a) and
connect it to plug “A” (see illustration below).
c) Install one of the new 6-pin connection cables (P/N 260175), connecting one
end to the main controller and the other to plug “C” (see below) on the module
installed in Step 2a).

3. Install the second Cable Splitter/Signal Booster Module at the Remote
Location
a) Determine the desired location for the remote display unit. It can be located up
to 656 feet (200M) from the unit.
Using eld-supplied 22 AWG to 18 AWG shielded twisted pair wire (EIA
485), run dedicated wires from that location to the unit. Two sets of twisted
pair wire are required -- one for the power and one for communication. The
communication wire should be shielded to prevent noise.
On the cable splitter/signal booster module installed in Step 2a), connect the
shield to screw terminal 0. Connect the power wires to screw terminals 1 and 2.
Connect the communication wires to terminals 3 and 4.
b) Install the second cable splitter/signal booster module (P/N 260735) in a eld-
supplied junction box to be recessed behind the remote display. Connect the
shield to screw terminal 0. Connect the power wires to terminals 1 and 2 and
communication wires to terminals 3 and 4, making sure that power and commu-
nication polarity is maintained.
WARNING: Improper wiring can damage the remote unit interface
display as well as the main system controller.
c) Attach the second 6-pin connection cable (P/N 260175) in the kit to plug “A” on
the remote cable splitter/signal booster module.
4. Install the Remote Display
a) Remove the back cover of the remote unit interface display (P/N 260178).
Position the back cover over the cable splitter/signal booster module installed in
Step 3b) and feed the 6-pin connection cable out through the hole in the cover
plate. Mount the back cover plate to the wall covering the cable splitter/signal
booster module.
b) Unsnap the face cover from the remote unit interface display. Locate the 6-pin
wire connection and connect the cable from the cable splitter/signal booster
module. Using the screws removed, re-attach the display to the back cover
plate. Snap the display face cover in place.
5. Verify power and communication polarity before re-powering the unit.
6. Turn power on to the unit. Set the Address of the Remote Display.
a) All displays have a factory-set address of 32; therefore, the address of the
remote display must be changed. To access conguration mode on the
remote display, press the UP
hold all three for at least 5 seconds. The display on the remote unit will be
