Set up your main station
Your third step is to set up and program your STX7500 main station. You will set the current weather, location, and other settings.
Programming the main unit
1. Open up the battery panel of the main station device and add four AA (1.5V) batteries (not included). The unit can also be operated using the supplied AC adaptor. Plug the barrel
end of the adaptor into the jack located on the bottom of the STX7500; plug the other end into a wall outlet.
2. Main unit will light up entire display, and a sound will tell you unit is defaulting to initial settings.
3. DO NOT TOUCH ANY BUTTONS FOR 10 MINUTES, WHILE THE STATION LOOKS FOR THE OUTDOOR SENSOR AND SCANS FOR THE WWVB SIGNAL.
4. The two devices will begin communicating in this time. You should see the main station pick up a temperature and channel reading. This shows that the two devices are in
communication.
5. Place the remote device outside the house.
a. Fog and mist will not harm your remote sensor, but direct rain should be avoided.
b. The sensor has a range of 30 meters, but intervening walls will lower that number. An outdoor wall or window may have a 20 to 30 foot resistance.
c. Consider mounting your device on an outside wall, directly opposite to the room where you plan to have your main station.
6. Once you have placed your outdoor sensor, check the main station to make sure the two devices are still communicating.
Setting the Weather
To begin, you must input the current weather conditions outside your house. This is because the forecaster technology works using current conditions to predict future conditions.
1. Immediately after set up, the weather icon will be flashing for 15 seconds.
2. Press “+” or “-” on the back of the unit to input the correct weather outside. It is recommended that you set your first forecast based on a local weather report.
3. Once you have established current weather, press the “REL/ABS” button, located on the back of the unit, again to exit
4. The main station will start to forecast 6 hours after the current weather is entered.
5. When the main station begins forecasting, you will see one of 6 different symbols in the weather forecast. This is your forecast for your area. The forecast is for 6 hours ahead.
6. At any time you can reset the weather forecast by holding down the “REL/ABS” button for 3 seconds. Then follow steps 2 and 3 again to set the new forecast.
7. When setting the weather, please note:
a. If the outdoor sensor reads below 0°C and you have input the weather to “rain” or “heavy rain” then your main station will display snow
b. The weather conditions should be reset if you change the altitude.
Setting Clock Automatically
After the main station has finished searching for the remote sensor, it will proceed to scan for the “WWVB” signal — this is an atomic clock transmission which is sent all across the
United States.
1. Buttons will not function while station is scanning for WWVB time signal.
2. While scanning the RCC icon
will flash on the main station.
3. When the RCC icon
stops flashing, the main station has successful updated with the correct time.
a. Your main station will automatically rescan for WWVB time signal every night at 2:00 a.m.. If the first attempt fails, station will scan again at 3:00, 4:00, and 5:00 a.m.
b. To manually start a new time scan, press and hold the “RCC” button, located on the back of the unit, for 3 seconds.
4. If the reception fails, the RCC icon
will disappear.
a. If reception fails, the main station will attempt to rescan for signal 4 times. Each time takes about 10 minutes.
b. If reception fails all four times, you can manually enter time (see next section). However, it’s best to let the main station attempt to automatically search for a signal for one
24 hour period.
5. You will see “DST” on the main display if clock is in Daylight Savings Time.
About the WWVB Signal
The NIST (National Institute of Standards and Technology) radio station, called WWVB, is located in Ft. Collins, Colorado. A team of atomic physicists continually measure every second
of every day to an accuracy of ten billionths of a second a day. That’s quite a clock! The team transmits the WWVB time continuously throughout the United States, and this signal can
be received up to 2000 miles away by your main station. However, transmission is best at night, which is why your main station will attempt to update every night at 2:00 a.m.
