Firstly, check that the wind-fan and the wind-vane can rotate freely before fixing the
unit. For correct and accurate readings it is important to mount the sensor so that the
front (marked E) is pointing in East-West direction. The wind sensor should now be
mounted using the screw or cable tie provided onto a solid wall/ panel mast or mast to
allow the wind to travel around the sensor unhindered from all directions (ideal mast
size should be from diameter 16mm to 33mm).
Once the wind sensor is fixed onto the mast, connect the cable to the corresponding
thermo-hygro sensor socket so that operating power supply can be received and data
can be transmitted to the base station.
