At every full hour the current air pressure is used as a basis for the display of a new graph bar. The existing graph is then moved one bar to the left.

Note:

For accurate barometric pressure trend, the intelligent weather station should operate at the same altitude. For example, it should not be moved from the ground to the second floor of the house. Should the unit be moved to a new location, discard readings for the next 48 – 60 hours.

LOW BATTERY INDICATOR

The low battery indicator will be displayed in the LCD when the battery power of the intelligent weather station is low. It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of the intelligent weather station.

Note: After battery change, both the intelligent weather station and the transmitter(s) need to be reset (see note ”Setting up”)

WEATHER INFORMATIONDISPLAY

The weather information display located at the last section of the LCD will display the weather forecast based on data received from channel 1 and the air pressure.

The intelligent weather station will automatically display the following information:

Maximum temperature of the day

Minimum temperature of the day

Probability of the weather forecast

Time frame for the weather forecast

Probability of snowfall

Probability of fog

Probability of glazed frost

Probability of tempest
