The Model PTS-O3 Precision Outdoor Thermistor Sensor provides precision remote temperature sensing for the Proliphix NT20e and NT120e/h Network Thermostats. The active sensing element is a highly stable precision thermistor material accurate to within +/- .36oF (0.2oC).The temperature-sensitive element is sheathed in a stainless steel tube and mounted inside a ventilated, treated, white PVC shield to minimize radiant energy and weather related effects.

FEATURES

2" x 4" weatherproof box
Five-year warranty
+/- .36oF (0.2oC) accuracy
Vented weathershield for quick temperature response
Moistureproof with 8ft lead

APPLICATION

The outdoor air temperature assemby should be located in the shade, away from all devices (such as exhaust fans) that would disturb the outdoor environment. A prefered location would be below the eaves, one foot down from the top of the wall, in a permanaently shaded spot.The sensor should be mounted horizontally, with the element to the right or left of the handibox. The weather shield assembly features a tapered fitting which allows the shield to be rotated by hand. Air vents on the shield should face downward. Internal mounting knockouts provide for direct wall mountingusing screws or toggle bolts.
