Location and Mounting (Fig. 1)
Mount the sensor where:
• cannot tamper with settings.
• there is good air circulation.
• it can measure true outdoor ambient temperature.
• surface is flat.
• wire distance between C7089U and thermostat is
less than 200 feet.
Do not mount the sensor:
• in direct sunlight.
• where hot or cold air blows on the sensor.
Discharge line from an outdoor compressor unit,
vent or fan causes inaccurate temperature
readings.
• where snow, ice or debris can cover it.
Use the following steps to mount the sensor:
1. Remove the sensor from the mounting clip.
2. Mark the area on the location selected for
mounting the sensor mounting clip.
3. Mount the clip.
