Mounting the units:
Using 915MHz wireless transmission gives users little restriction on placement because all
units can be positioned virtually anywhere within a 330 ft / 100 meters radius of the base
station. Please ensure that the cable included in this set meets your distance
requirements (see accessories in the main user manual for adding extension cables).
Important: Ensure all signals can be received and/or all cable distances meet with your
requirements at the point of fixing particularly before you start drilling any mounting holes.
Wind sensor
Secure the main unit to the shaft of the mast holder using the single screw provided with
the CUPS ON THE BOTTOM. Now fix the entire unit to a suitable mast using the U-bolt,
washers and nuts found in this set.
Note: For best results mount the wind sensor onto a mast to allow the wind to freely travel
from all directions to enable an accurate reading (ideal mast size should be from Ø
5

” to

”). Ensure that the cable of the wind sensor meets your distance requirements
Thermo-hygro Sensor
To wall mount the thermo-hygro sensor, fix the wall holder onto the desired wall (2 screws
are supplied), plug the sensor firmly into the wall holder and then carefully replace the rain
cover back over the thermo-hygro sensor.
