(pack of 25) Low cost temporary temperature sensor that enables space control if
the permanent room or duct sensor is
not installed.
Parts for CE Compliance:
550-705 Clamp-on ferrite filter (10 pack)
588-100 series Approved 2-RJ11 RTS cable in 25’,
50’, or 100’ (7.6-m, 15.2-m, 30.48-m).

Warning/Caution Notations
CAUTION:
Equipment damage or loss of data may
occur if you do not follow the procedures
as specified.
Expected Installation Times
10 minutes.
Required Tools and Materials
• Flat-blade screwdriver (1/8-inch blade width).
•Smallflat-blade screwdriver
• Cabling and connectors. See the section.
• Cordless drill/driver set
Prerequisites
• MBC or RBC enclosure mounted with at least
one open slot on the C-BUS and AC power
connected.
• CE Compliance requirements met, if needed.
• Termination blocks installed, if any.
• Authorized modem installed if connection to a
public telephone network is required.
• One 115V or 230V receptacle (depending on
device) to power the Trunk Interface II.
If the controller is being installed on a box
with1ormorestagesofelectricheat,
the 550-809 MOV with pre-terminated
spade connectors must be installed across
the manufacturer-supplied airflow switch.
MOV’s can be installed at the time the
controller is factory mounted; coordinate
with the box manufacturer prior to order
placement. For field installation, see Metal
Oxide Varistor Kit Installation Instructions
(540-986).
Instructions
All wiring must conform to NEC and local
codes and regulations.
1. Secure the mounting rail (Figure 1) in the
controller’s desired location.
2. Place the ESD wrist strap on your wrist and attach
it to a good earth ground.
3. Remove the controller from the static proof bag
and snap it into place on the mounting rail.
4. Connect the FLN (Figure 2).

6. 540-104 and 540–104C: Install the Autozero
Module and connect the wires to DO6 (Figure 5).
See installation instructions 540-199.
7. Plug the room temperature sensor cable into the
RTS port (Figure 1).

As a standard grounding procedure, ensure
that 3"-5" ground wire is connected directly
on the common terminal on the secondary
side of the 24 Vac transformer.
9. Connect the tubing from the air velocity sensor
pickups to the ports on the controller or Autozero
Module (Figure 5). Connect HI to HI and LO to
LO.
The installation is complete.
CE Compliance
If CE compliance is required, the Equipment
Controller must be mounted in a grounded metal
enclosure and a ferrite filter must be placed
approximately 1 cm from the end of the cable
being shielded (RTS cableand point wiring for AI3)
(Figure 4).
TEC0320R3
1- 2 cm
1Place the filter 1-2 cm
from the end of the cable
or wiring to be shielded.
2Wind the cable tightly
twice around the filter.
3Close the filter and wrap
with a zip tie.

CAUTION:
The controller’s DOs control 24 Vac
loads only. The maximum rating is 12
VA for each DO. Use an interposing 24
Vac relay module (such as P/N such as
P/N 550-054) for any of the following:
• VA requirements higher than 12 VA
• Separate transformers to power the load
• Direct current (DC) power requirements
