WIRING
Mounting the Outdoor Sensor
(Not required if window protection isn’t needed)
Location
Mount the sensor where:
• it cannot be tampered with.
• there is good air circulation.
•
surface is flat.
• wire distance between sensor and humidistat is less than 200 feet.
• it can measure true outdoor ambient temperature.
Do NOT mount the sensor:
• in direct sunlight.
•
where snow, ice or debris can cover it.
•
where hot or cold air blows on the sensor. (For example, a discharge line from an outdoor compressor unit,
vent or fan can cause inaccurate temperature readings.)
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. Image on right shows typical locations for out-
door sensor.
