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:

an outdoor compressor unit, vent or fan can cause inaccurate temperature
readings.)
