Temperature and Humidity Sensor – Outdoor Mount
One or several outdoor air temperature and humidity sensors may be utilized at a site. The
sensor contains a Type II 10kΩ thermistor for the temperature reading and a 0-10VDC
relative humidity sensor for the humidity reading. This sensor can be mounted using ½” EMT
conduit or by securing the sensor housing with approved fasteners. The probe that sticks out
of the sensor should always be pointed downward to protect it from the elements. To
improve sensor readings, mount this in a location that will be free from the elements and
direct sunlight.
Carbon Dioxide Sensor – Duct Mount
A duct mounted carbon dioxide sensor can be
used to implement CO2 based demand control
ventilation for RTU operation. The sensor will
output a 0-10VDC signal and should be installed in
the return duct in order to get an accurate CO2
reading of the space. Ensure correct orientation of
the sensor in the airstream by the airflow arrows
present on the sensor.
