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.
