Base Station
With two foldable legs at the back of the unit, the base station can be
placed onto any flat surface or wall mounted at the desired location by
the hanging holes also at the back of the unit. It is important to check
that the 433MHz (if using wireless connection) and the DCF77 radio
controlled time signal can be received before permanently mounting
any of the units. Should the base station not display the 433MHz
weather data from the sensors or the radio controlled time from the
desired location, then relocate the units. Once the signals are re-
ceived, the system can be affixed. Also if you have selected to use
cable connection, ensure that distances can reach all desired loca-
tions before affixing any unit permanently
Mounting the Wind Sensor onto a mast
Firstly, check that the wind-fan and the wind-vane can rotate freely
before fixing the unit. For correct and accurate readings it is impor-
tant 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 provided onto a mast to allow the wind to travel around the
sensor unhindered from all directions (ideal mast size should be from
Ø16mm – Ø33mm).
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 sta-
tion.
Mounting the Rain Sensor
For best results, the rain sensor should be securely mounted onto a
horizontal surface about 1 meter above the ground and in an open
area away from trees or other coverings where rainfall may be re-
duced causing inaccurate readings.
When securing into place, check that rain excess will not collect and
store at the base of the unit but can flow out between the base and
the mounting surface (test by pouring clean water).
After mounting the rain sensor, connect the cable to the thermo-hygro
sensor at the corresponding socket so power supply can be received
and data be transmitted to the base station
The rain sensor is now operable. For testing purposes, very slowly
pour a small amount of clean water into the rain sensor funnel. The
water will act as rainfall and will be received and displayed at the
base station after about 2 minutes delay i.e. when the reading interval
is reached (to clear this testing data on the base station, refer to the
section “MIN/MAX Mode” below).
