to prevent electrical shock or equipment damage.
Location and Mounting (Fig. 1)
Mount the sensor where:
•
setting can not be tampered with.
•
there is good air circulation.
•
it can measure the true outdoor ambient temperature.
•
surface is flat.
•
he wire distance between the C7089 and thermostat
is less than 200 feet.
Do
not
mount the sensor:
•
in the direct sunlight.
•
where hot or cold air blows on the sensor. Discharge
line from an outdoor compressor unit, vent or fan will
cause 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 surface where the C7089B
mounting clip will be mounted.
3.
Mount the clip.
