LOW TEMPERATUE ALERT (ALARM AT 4
C)
This weather station enables the low temperature alert (alarm) function. User may choose to
switch it On or Off.
User may press the low temperature alert key to activate the alarm (the low temp alert icon
will then be displayed to indicate that the alarm is "on").
After the alarm is switched on, once the measured outdoor temperature has dropped to 4
C,
the low temperature alarm will be triggered. The alarm will then sound and the low
temperature alarm icon will be blinking on the LCD. The alarm duration will be about 1.5
minutes.
HYSTERESIS OF LOW TEMPERATURE ALARM
To compensate for the fluctuation of the measured outdoor temperature, which may cause
the low temperature alarm to sound constantly if the measured reading is close to 4
C, a
hysteresis function has been implemented for the alarm.
If the current value drops to 4
C, the alarm will be activated (if it has been enabled).
Then when the temperature rises to 4.6 C and thereafter again drops to below 4°C, the data
will be blinking, but no alarm will be activated. With the pre-set hysteresis of 1 C, it has to
rise back to above 5°C and drop below 4 C to trigger the alarm again.
915 MHz RECEPTION
The Weather station should receive the temperature data within 5 minutes after set-up. If the
temperature data is not received 5 minutes after setting up (not successfully continuously,
the outdoor display shows “- - -” ), please check the following points:
1.
The distance of the weather station or transmitter should be at least 1.5 to 2 meters
away from any interfering sources such as computer monitors or TV sets.
2. Avoid positioning the Weather station onto or in the immediate proximity of metal
window frames.
