Product Overview

The HW2 Series of humidity sensors for living space is a exible multisensor platform for use with BAS controllers
designed to accept 4 to 20mA, 0 to 5Vdc or 0 to 10Vdc outputs. HW2 Series sensors are available with three user
interface options: touchscreen, LCD with three buttons and blank. Humidity and temperature sensors are included
with all HW2 Series sensors.

The HW2 Series sensor measures the RH and temperature in a room and provides analog outputs to a controller.

1. Remove the cover from the base at the bottom of the device.

2. Position the sensor base vertically on the wall 1.35 m (4.5 ft.) above the oor with the “UP” arrow facing upward. Locate away
from windows, vents and other sources of draft. If possible, do not mount on an external wall, as this may cause inaccurate
temperature readings.
