: If the new controller has a newer
firmware revision than the old controller, then
skip to the third bullet.
• If the old controller communicates with the
field panel, then update the controller initial
values at the field panel.
• If the old controller does not communicate
with the field panel, but communicates with
the CIS, or if the controller is stand-alone,
then record the initial values (those marked
with an asterisk (*) on the CIS display).
Record these values in Table 1 at the end of
these instructions.
• If the old controller is not communicating at
all, or if the controller you are installing has a
newer firmware revision than the old
controller, then while at the field panel,
follow these steps:
a. Obtain a field panel Point Definition
Report for the LCTLR point. Record the
values in Table 1.
b. View the initial value block. (This
information is valid only since the last
update was made). Record the values in
Table 1.
c. Delete the LCTLR point from the field
panel.
3. Replace the old controller as follows:
The following tasks can be performed by the
electrician:
a. Remove power from the controller.
b. If the old controller has the RTS plug
between the LAN trunk and point
terminations, then disconnect the wires
from the power trunk terminal block. If the
old controller has the RTS plug on the
opposite end of the board from the power
trunk terminal block, then remove the power
trunk terminal block.
c. Remove, in order, the controller’s:
• LAN trunk terminal block
• point wiring
• room temperature sensor
d. Remove the old controller assembly from
the mounting rail.
e. Carefully remove the new controller
assembly from the anti-static bag. Center it
over the mounting rail and snap it securely
into place.
f. If the old controller has the RTS plug
between the LAN trunk and point
terminations, then remove all terminal
blocks (except the power trunk) from the
new controller. If the old controller has the
RTS plug on the opposite end of the board
from the power trunk terminal block, then
remove all terminal blocks.
g. Plug, in order, the controller’s:
• pre-wired LAN trunk
• point wiring
h. If the old controller has the RTS plug
between the LAN trunk and point
terminations, then rewire power to the
power trunk terminal block. If the old
controller has the RTS plug on the opposite
end of the board from the power trunk
terminal block, then plug the power trunk
terminal block from the old controller into
the new controller.
i. Connect the room temperature sensor.
j. Power up the controller.
The following tasks can be performed by the system
specialist:
4. Set the address and application at the new
controller.
5. Based on what you did in Step 2, do one
oneone
one of the
following:
• If you updated the initial values from the old
controller at the field panel, then when you
set the address and application for the new
controller, the field panel will automatically
send the initial values down to the new
controller. Once this takes place,
replacement is complete.
