ZS Outdoor Air Sensors
ZS-OA

Temperature Only, Temperature Plus Humidity

The Carrier ZS line of communicating outdoor air sensors are designed to measure the air temperature and/or humidity outdoors. Designed for outdoor mounting, the UV-resistant plastic shield keeps the sensor out of the sunlight and allows for excellent air circulation. These outdoor sensors have etched Teflon® lead wires and can withstand high humidity and condensation environments. They are made to perform in a wide range of temperature and moisture conditions.

The ZS outdoor air sensors connect directly to the dedicated sensor network (Rnet) of a Carrier i-Vu controller. This communicating sensor network supports up to 15 ZS sensors through a single port, eliminating the need to consume multiple inputs on the controller.

Averaging temperature sensor probe: Bendable aluminum / 3/16 in. diameter / Length of 8, 12, or 24 ft. specified at time of order

Sensing Element
Temperature Range: 20° to 120°F (-5° to 50°C)
Accuracy: ±0.36°F (0.2°C)
