The user may at any time switch from cable connection to using
433MHz (or vice versa) by simply disconnecting (or connecting) the
cable from the base station to the sensor. When the base station
detects no cable connection to the sensors, the base station will
automatically change to using 433 MHz for reception of the weather
data from the sensors.
The data receiving intervals are as follows:
-
Using cable connection data is updated every 8 seconds.
-
Using wireless 433 MHz data is updated from 16 to 128 second
intervals depending on wind speed and rain activity.
Using the AC adaptor to operate the base station will also supply
power to the sensor if the cable is connected to it. Batteries used for
433MHz transmission may be left in the sensor when using cable
connection for power back up in case of AC power failure. A loss of
power would desynchronize the base station and the sensor and no
weather data will be received. To Synchronize the units so that the
weather data can be received, press and hold the PLUS (+) key for 2
seconds. However in general, batteries that will not be used for long
periods should be removed to avoid leakage.
Wireless 433MHz transmission:
Using 433MHz wireless transmission of weather data from the sensor
to the base station will provide users greater freedom as to where
units can be positioned without the need to be restricted by cable.
Note:
If no outdoor weather data is displayed or the signal to the sensors is
lost during setting up, mounting, changing of batteries to the sensor
or plugging or unplugging cables, simply press and hold the PLUS (+)
key for 2 seconds and a short beep will sound to synchronize the
base station to sensors. Without being synchronized, weather data
will not be received.

8. Function
test
Once the weather station is powered up, perform a function test by
checking that the weather data is received. To do this, press the
DISPLAY, PRESSURE or WIND keys to toggle through the relevant
LCD sections:
1) Indoor temperature and humidity
2) Outdoor temperature and humidity
3) Outdoor wind chill
4) Dew

5) Rainfall

6) Rainfall

7) Rainfall

8) Relative and absolute pressure
9) Wind speed, wind direction and wind direction in degrees
If any readings cannot be received from the sensors, lines (- - -) will
be displayed in the respective weather sections of the LCD. In this
case, check that all cables are correctly inserted into the correct
sockets and/or check the batteries in the outdoor thermo-hygro
sensor and press and hold the PLUS (+) key for 2 seconds and a
short beep will sound to synchronize the base station to the sensors
otherwise no weather data will be received..
Some weather readings such as wind speed and direction may not
appear immediately on the LCD if the wind-fan or vane of the wind
sensor is moved. This is due to the set reading time intervals for the
wind readings. However the current wind speed or direction will be
displayed once the time reading interval is reached. For rainfall, the
interval readings may take up to 2 minutes before the data is
displayed on the LCD.
9. Mounting
Important Note
Prior to drilling mounting holes and permanently affixing any of the
units, please ensure the following points are considered:
•
Cable lengths of the units meet with your distance requirements
at the point of fixing
•
Signals from the sensors can be received by the base station at
points of mounting
12
•
Radio controlled time signal can be received at the point of
mounting
NOTE:
The WWVB receiver is located in the base station.
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 WWVB
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 received, the system can be affixed. Also if you have selected to
use cable connection, ensure that distances can reach all desired
locations before affixing any unit permanently
NOTE
: For reception of WWVB time/date signal, do not mount the
base station closer than 5 feet from a computer, florescent lights or
other electrical appliances. Do not mount the base station on a wall
that has metal heat/AC ductwork in the wall behind the base station.
For best WWVB reception place the base station near a window
facing Colorado. WWVB reception will be obtained easiest in the
nighttime hours when the WWVB signal is strongest.
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
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 provided onto a mast to allow the wind to travel
