9. After viewing Figure 6, install a clamp-on ferrite
filter on the room temperature sensor cable and
plug the cable into the RTS port on the controller
(Figure 1). Use only an approved 588-100 series
cable as described in the Product Numbers
section. Consider strain relief to ensure long-
term effectiveness due to added weight of the
filter.
10. Connect the power trunk as shown in Figure 5.
DO NOT apply power to the controller.
11. Connect the tubing from the air velocity sensor
pickups to the HI and LO ports on the controller,
or on the Autozero Modules (if present). Make
sure that the "HI" and the "LO" pressure sides of
the sensors are connected to the corresponding
"HI" and "LO" sensor ports on the controller or
Autozero Modules (Figure 2).
The installation is complete.

Replacement Instructions

CAUTION:
Replacement of a TEC requires you to
record, re-enter, or update the initial point
values of the controller being replaced.
These are the points marked with an
asterisk (*) on the CIS display.
NOTE: CIS Rev. 2.0 or higher is required for
controller replacement.
1. Place the ESD wrist strap on your wrist and
attach it to a good earth ground.
2. Before disconnecting the old controller, do one
of the following:
NOTE:
If the new controller has a newer
firmware revision than the old
controller, skip to the third bullet.
If the old controller communicates with the
field panel, update the controller initial values
at the field panel.
If the old controller does not communicate
with the field panel, but communicates with
CIS, or is stand-alone, record the initial
values in Table 1.
If the old controller is not communicating or
has a newer firmware revision, use the
following steps to update the field panel:
Siemens Building Technologies, Inc.
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:
a. Remove power from the controller.
b. If the old controller has the RTS plug
between the FLN and point terminations,
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, remove
the power trunk terminal block.
c. Remove, in order, the controller's:
FLN 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 FLN and point terminations,
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, remove all terminal blocks.
g. Plug, in order, the controller's:
Pre-wired FLN
Point wiring
NOTE: Wiring to DI3/AI3 requires a clamp-on
ferrite filter (Figure 6). Strain relief
must be provided to ensure long-term
effectiveness due to added weight of
the filter.
