provide a more accurate barometric pressure & weather
forecast reading. (For more information, see “WEATHER
FORECAST & BAROMETRIC PRESSURE” section)
SETTING UP THE WIRELESS THERMOHYGROMETER
1. For the rst installation, always turn on the home
unit and then the remote sensor. Set Channel 1 for the
rst remote sensor. Set channel 2 and channel 3 for the
2
nd

temperature & humidity of the selected channel will ap-
pear on the main unit.
WEATHER FORECAST & BAROMETRIC PRESSURE
The unit predicts weather condition of the next 12 –
24 hours based on the change of atmospheric pressure.
The coverage area is around 30 – 50km. The weather
forecast is based on atmospheric pressure change and is
about 70-75% correct. As weather conditions cannot be
100% correctly forecasted, we cannot be responsible for
any loss caused by an incorrect forecast.
Sunny Slightly cloudy Cloudy
Rainy Stormy
The current weather forecast is the one highlighted
by a black-outlined square box.
To obtain an accurate weather forecast & baromet-
ric pressure reading, you need to input your current al-
titude. After the reset of the unit, it will enter altitude
setting mode. Press [] or [] to set the pressure
unit in hPa, mb or in Hg. Press [PRESSURE] to conrm.
Then enter your current altitude in meter or feet. Press
[PRESSURE] to conrm and exit the setting. You can also
hold [PRESSURE] button to enter altitude setting mode
during normal use.
Press [PRESSURE] button to select pressure unit be-
tween hPa, in Hg & mb.
IMPORTANT NOTE:
Dierent geographical location such as inland area
or coastal region has dierent weather forecasting re-
sponse. In case your weather forecast always show rainy
or stormy over a long period of time and does not re-
ect the actual weather condition, it is necessary to fol-
low below procedure for ne tuning the weather fore-
cast’s accuracy.
1. Check the current weather condition outdoor.
2. Enter altitude setting mode and adjust altitude ac-
cordingly. Increase or decrease altitude setting by 20m
(or 60ft) each time and exit. Repeat this step until the
weather forecast icon matches with the current outdoor
