Setting up using the AC adaptor:
To operate using cable connection, simply use the enclosed 32ft
cable and connect the thermo-hygro sensor to the base station. Once
the connection is detected, the base station will automatically
continue reading the data from the sensor.
1) Power up all the sensors as described in setting up using
batteries above
2) Using the AC adaptor (included), plug it into the mains outlet and
power up the base station by inserting the adaptor jack into the
DC 6.0V socket located on the side of the base station
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.
Every time the thermo-hygro sensor is powered up (for example after
a change of batteries), a random security code is transmitted and this
code must be synchronized with the base station to receive weather
data.
The data receiving intervals are as follows:
-Using cable connection data is updated every 8 seconds.
When the base station is powered up, a short beep will sound and all
LCD segments will light up for about 5 seconds before it enters into a
15 minute learning mode to learn the sensors security code. After the
learning mode (or by pressing the MIN/MAX key at anytime), the base
station will start the WWVB radio controlled time reception.
-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.
Note for WWVB Radio Controlled Time:
The time and date display is based on the signal provided by the
highly accurate government operated atomic clock in Ft. Collins,
Colorado. This radio-controlled clock does not only provide for the
weather station’s time and date display but also functions as the time
and date source for all of this weather station’s memory and history
values using time and date information.
Wireless 433MHz transmission:
LCD backlight:
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.
When using the power adaptor, the LCD backlight is switched on
continuously. Under battery operation, the LCD backlight is switched
on for 15 seconds intervals when any key is pressed.

Operation using cable connection or wireless 433MHz
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.
Cable Connection:
Using this method of operation will provide interference free transfer
of the weather data from the sensors to the base station. The data
sending interval from the sensors to the base station will also be more
frequent compared to using 433MHz transmission and will result in
higher power consumption. Therefore batteries will have a shorter life
span for cable connection compared to using 433MHz.
