the IDS and CIR GND terminals to verify the sensor is
properly installed.
• Locate the sensor as you would locate a thermostat.
• Maximum wire length from sensor to thermostat is
300 feet.
• Use an ohmmeter to measure the resistance (kΩ) of the
sensor. The resistance reading will depend on the indoor
temperature (see table from OUTDOOR SENSOR
installation section on page 20).
• Follow the installation instructions provided with
the sensor.
2. Run a 2-wire cable from the sensor to the thermostat.
