Press the CH button to select Ch1, Ch2, Ch3 or auto-channel scroll.
Auto scroll-channel
will show a circling arrow
below the channel number and will rotate
through each channel approximately every 5-8 seconds
Setup with Multiple Outdoor Sensors
The forecast station will accommodate up to three remote outdoor sensors (TX142TH or TX14TH). The channel
selection button allows you to easily see the temperatur
e in various locations: outdoors, baby’s room,
greenhouse, basement, etc. Monitor remote temperature in up to 3 locations within a 200 ft. wireless range
of the forecast station.
To connect multiple remote sensors to the forecast station:
1. Remove the battery cover from all the sensors (Leave battery covers off until all sensors are
received by the forecast station).
2. Set the
first
outdoor sensor to Channel 1 and insert 2 AA batteries.
3. Set the
second
outdoor sensor to Channel 2 and insert 2 AA batteries.
4. Set the
third
outdoor sensor to Channel 3 and insert 2 AA batteries.
5. Press and hold the CH button on the forecast station for 5 seconds. The forecast station will search
for all outdoor sensors.
6. Press the TX button on each outdoor sensor to transmit RF signal.
7. When RF connection is established, the respective temperature & humidity for each of the selected
channels will appear on the main unit.
8. Allow the sensors and the forecast station to stay 5-10 feet apart for 15 minutes to establish a solid
connection.
9. Install the battery covers on each sensor.
10. After 15 minutes place the remote sensor
s in appropriate locations (see “
position the outdoor sensor
”).
Press and release the CH button to view channel 1, 2 or 3 on the forecast station when multiple sensors are
used.
Note:
You cannot change channels if only one sensor is connected.
Channel Scroll
Press and release the CH button until you see
appear in the outdoor data area. The forecast station will
automatically rotate through the channels for all connected sensors.
Press and release the CH button to lock the forecast station into one channel. Then view channels individually
with a press of the CH button.
WWVB Radio-controlled Time
The NIST radio station, WWVB, is located in Ft. Collins, Colorado, and transmits the exact time signal
continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away
through the internal antenna in the forecast station
. However, due to the nature of the Earth’s Ionosphere,
reception is very limited during daylight hours.
The forecast station will search for a signal every night when reception is best. The WWVB radio station derives
its signal from the NIST Atomic Clock in Boulder, Colorado. A team of atomic physicists continually measures
every second of every day to an accuracy of ten billionths of a second a day. These physicists have created an
international standard, measuring a second as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum.
This atomic clock regulates the WWVB sensor.
