will reduce the range significantly). It is very important that the remote unit not
be placed in direct sunlight and should be protected from extreme weather.
This allows you to receive an accurate outside temperature reading and weather
forecast.
Note: For more details on synchronization, please refer to sections entitled,
“Wireless Remote Temperature Transmission” or “Transmission Troubleshooting.”
Weather Forecast
The main unit has a built-in barometer. The local weather forecast and weather
tendency are predicted using the rate of change in atmospheric pressure based
upon a norm. When you first turn on the unit, it takes 48 hours for the unit
to sense and calculate the norm or the middle pressure level. After this time,
the unit shows weather tendencies due to an increase or decrease in the baromet-
ric pressure. The icon on the unit shows what the weather tendency will be over
the next six hours.
Weather tendency is indicated by and up or down forecast arrow. (See table below.)
1. The up arrow
indicates a significant increase in atmospheric pressure.
This normally means the weather is going to improve.
2. The down arrow indicates a significant decrease in atmospheric
pressure. This means the weather is going to get worse.
Note: If the unit continually gives incorrect forecasts, it can be corrected by
re-syncing the unit on a partly cloudy day. This allows the barometer to find the
right barometric pressure level without being too high or low.
3. The forecast icon
without an arrow indicates a steady/insignificant
change of atmospheric pressure. This means the weather will remain unchanged.
