ACC-TSENAir Temperature Sensor
Connect to the thermostat backplate as shown
Use 18 - 22 gauge 2 conductor unshielded thermostat wire. Wire length not to exceed 200 feet.
The Air Temperature Sensor measures indoor or outdoor air temperature with a range of -20 to 120 degrees F.
If used indoors as a remote temperature sensor, the sensor will read room temperature and send the
information to the thermostat. If used as an outdoor temperature sensor, the sensor may be used to provide
outdoor temperature information (which is not used to control heating or cooling). The Air Temperature
Sensor should be mounted out of direct sunlight and in a place that is protected from direct rain and snow.
Mounting the sensor under an eave of a roof or under an overhang of a building is recommended.
