INTRODUCTION
The Duct Sensor provides a high precision temperature and humidity sensor that is pre calibrated
from the factory to a Node or Stat. The Duct Sensor is easily mounted on a duct with the help of self-
tapping screws. The Duct Sensor uses a proprietary 1-wire protocol to communicate with a master
device such as a SmartNode.
PACKAGE CONTENTS
•Duct sensor
•Mounting accessories
•One Sensor bus cable of 20ft length
•Modular pipes (100 and 150mm) to allow the air.
in the duct to be pitot.

1. Drill a hole of dia greater than 18mm for the pipe to enter the Duct. Mount the Duct Sensor
using two #8-1.5” self-tapping screws as shown in Figure 1. The transmitter must be
installed vertically with the air inlet pipe pointing perpendicular to the duct.
Figure 1
2. Choose the length of the pipe as per the duct dimension. The lengths of the pipes
provided are 100 and 150mm long. There is an end cap provided to make the air pitot
towards the sensor. Refer Figure 2. To lock and unlock the tubes.
Align the arrow on the pipe to the lock
symbol and rotate clockwise to secure the position
Rotate the pipes anti-clockwise to separate them.
Figure 2
PRECAUTIONS
•Failure to wire devices with the correct polarity when using a shared transformer may
result in damage to any device powered by the shared transformer.
•Mount the tubing so that the tube is in direct line of a breeze or draft.
•Turn off the power before wiring. Never connect or disconnect the wiring with the
power turned on. Do NOT allow live wires to touch the circuit boards.
•Install in accordance with all state and local codes.

1. Turn the power OFF. Connect one end of the Sensor Bus cable to one end of the RTS
port on the Smart Node and the other end to the IN port of the Duct Sensor as shown in
Figure 3. Set the Daisy chain switch to NO position if there is only one Duct Sensor
connected.

2. Power to the Duct Sensor is provided through this cable; no external power wiring is
required. If an additional Duct sensor needs to be connected, connect the other Sensor
Bus cable to one end of the OUT port of the Duct Sensor and the other end to the IN port
on the Duct Sensor. See Figure 4 for connections.
3. To set addresses on the Duct Sensor, open the top cover and find the rotary address
setting switch on the PCB. The position is marked from 0 to 3. Available addresses on the
Duct Sensor are 0, 1 and 2. Address 3 is not available for Daisy chain.

4. To enable Multiple Duct Sensor communication, the Daisy Chain switch must be set to
Yes . When there is no requirement for additional sensors to be connected to the OUT
port of the DPS, the
Daisy Chain switch must be set to No . See Figure 4.
