Product Data Sheet
Combination Zone Sensors
Trane™ relative humidity and temperature sensors utilize a polymer capacitive-sensing element for reliable sensing
accuracy and superb recovery from saturation. Temperature output is provided by a 10 kΩ, Type II thermistor. Both sensors
are housed in a common enclosure for reduced installation costs and improved appearance.
