WIND SENSOR
The wind sensor must be installed with the front of the sensor (the solar panel) facing true
South, or the reported wind direction will not be accurate. Mount within the 200-foot wireless
range of the thermo-hygro sensor and on the same side of the house. The roof may or may not
be an ideal mounting location. Secure the main unit to the shaft of the mast holder. Use the
right-angle adaptor if the wind sensor will be mounted on a horizontal mast or surface.
Fasten the wind sensor to a suitable mast using the two U-bolts, washers and nuts included.
Note: Mount the wind sensor onto a mast, at a minimum height of 6 feet, so the wind can
reach the sensor unobstructed from all directions for an accurate reading. The ideal mast is
between 0.62" and 1.3” in diameter. The wind sensor DOES NOT have replaceable batteries; it
consumes solar power and charges the internal battery pack automatically.

Note: Do not open the wind sensor. This will void the warranty.
RAIN SENSOR
The rain sensor should be mounted on a level surface in an open area within the 200-foot
wireless range of the thermo-hygro sensor and on the same side of the house. Mount the rain
sensor at least 6 feet off the ground and level for optimum wireless transmission. The rain
sensor should be accessible to allow for periodic cleaning of debris or insects.

THERMO-HYGRO SENSOR
The thermo-hygro sensor is "weather resistant", but not "water proof". To ensure an extended
life for the sensor, mount it in a semi-covered place out of the elements at a minimum height of
6 feet. An ideal location for the thermo-hygro sensor is under the eaves on the North side of
the house to avoid the effects of sunlight. Mount the sensor 18" down from the eaves to
ensure optimum performance. This will assure the temperature of the air coming out of the
attic will not affect data collected by the sensor.
To wall mount the thermo-hygro sensor, fix the wall holder onto the desired wall using the
included screws, plug the sensor firmly into the wall holder and replace the rain cover if it is not
already in place. NOTE: After mounting the units, if the weather data is not received, press and
hold the ▲UP ARROW key for 2 seconds to synchronize the wireless display to the sensors.
