ABOUT WWVB (radio-controlled time)
The NIST (National Institute of Standards and Technology—Time and Frequency Division) 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 indoor weather station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The Wireless Weather Stations 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 measure 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. For more information about WWVB please see the NIST website at
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the Wireless Weather Station and remote thermo/hygro sensor 3 to 5 feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote thermo/hygro sensor first then into the Wireless Weather Station. (All remote thermo/hygro sensors must be started before the Wireless Weather Station)
In this time the Wireless Weather Station and remote thermo/hygro sensor will start to talk to each other and the display will show both the indoor temperature/humidity and an outdoor temperature/humidity. If the Wireless Weather Station does not display both temperatures after the 15 minutes please retry the set up as stated above. After both indoor and outdoor temperatures and humidity are displayed for 15 minutes you can place your remote thermo/hygro sensor outdoor and set your time.
The remote thermo-hygro sensor should be placed in a dry, shaded area. The thermo­hygro sensor has a range of 330 feet. Keep in mind that the 330 feet is in open air with no obstructions and that radio waves DO NOT curve around objects. Actual transmission range will vary depending on what is in the path of the signal. Each obstruction (roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal range in half.
Example: A Wireless Weather Station with a 330 feet range is mounted on an interior wall, so that the signal has to pass through one interior wall, one exterior wall, and across the 10 feet width of the room between the 2 walls. The first wall will reduce the range to 165 feet, and the second wall will reduce the range to 87 feet. Factoring in the 10 foot room, this leaves a maximum of 77 feet of remaining signal range.
This allowance is typically enough for a frame wall with non-metallic siding; however certain materials can reduce range even further. Metal siding, stucco, and some types of glass can reduce signal range by as much as ¾ or more, compared to the ½ reduction typical of most obstructions. It is possible to receive a signal through these materials, however maximum range will be much less due to their tendency to absorb or reflect a much larger portion of the sensor’s signal.
Battery Installation
BATTERY INSTALLATION (When on thermo/hygro sensor is being used)
1. First, insert the batteries to the thermo/hygro sensor (see “A. Remote Thermo/hygro Sensor” below).
2. Within 2 minutes of powering up the sensor, insert the batteries to the Weather Station (see “B. Wireless Weather Station” below). Once the batteries are in
place, all segments of the LCD will light up briefly. Following the indoor temperature and humidity, and the time as 12:00 will be displayed. If they are not shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them. Once the indoor data is displayed user may proceed to the next step.
3. After the batteries are inserted, the Weather Station will start receiving data signal from the sensor. The outdoor temperature and humidity should then be displayed on the Weather Station. If this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1 and the signal reception icon is no longer shown.
A. Remote Thermo/Hygro Sensor
1. Remove the mounting bracket. The bracket snaps
on and off easily.
2. Remove the battery cover, by sliding the cover down.
3. Observing the correct polarity install 2 AA batteries.
The batteries will fit tightly (to avoid start-up problems make sure they do not spring free).
4. Replace the battery cover by sliding upwards. Be
sure battery cover is on securely.
B. Wireless Weather Station
1. Remove the battery cover (the cover has white writing on it).
2. Observe the correct polarity, and install three Alkaline AA
3. Do not press any buttons for at least ten minutes. If a button is
pressed before the indoor weather station has received information from the TX29UD-TH sensor, no data will be received from that sensor until reset.
4. Replace the battery cover.
Sensor signal reception icon*
* When the signal is successfully received by the Weather Station, the icon will be switched on. (If not successful, the icon will not be shown in LCD) So the user can easily see whether the last reception was successful (icon on) or not (icon off). On the other hand, the short blinking of the icon shows that a reception is being done now.
Battery Cover
If the signal reception is not successful on the first frequency (915MHz) for 45 seconds, the frequency is changed to 920MHz and the learning is tried another 45 seconds. If still not successful the reception is tried for 45 seconds on 910MHz. This will also be done for re-synchronization.
II. Start Up Sequence
A. Initial Start
1. Immediately after the batteries have been installed, the Wireless
Weather Station will sound a “beep”, and the LCD will completely light up for a brief moment.
2. All information will then appear in normal mode, with “12:00” as
the default time and “SA.1” as the default date (2006 as the year).
3. The indoor temperature and humidity, and barometric air pressure
(as 29.92 inHg) will also be displayed.
4. There is a “satellite” icon that appears in the bottom portion of the
LCD, between the outdoor temperature and humidity — this icon informs the user that the indoor weather station is looking for signals from the remote thermo/hygro sensor. Within five minutes the remote temperature and humidity should be displayed—if not, remove batteries from all units and repeat battery installation, the remote thermo/hygro sensor first, then the Wireless Weather Station.
B. WWVB Reception
1. Once the batteries are installed in the Weather Station, it will
automatically search for the WWVB signal. If it receives a good signal (which is unlikely during daylight hours in most locations), the WWVB reception indicator (looks like a tower icon) will flash. The Wireless Weather Station requires five full minutes of good reception to successfully capture the signal and set to the correct hour, minute, second, month, day and year. If the signal recep tion is not successful within ten minutes, the signal search will be cancelled and will automatically resume every hour until the signal is successfully captured.
2. The signal is sent from Ft. Collins, Colorado only and is similar to
an AM radio signal. Atmospheric interferences such as storms, sunspots, and even sunlight will cause the signal to not travel as far.
3. To maximize reception, place the Wireless Weather Station in a
window facing Colorado, at least six feet from any electrical source (computers, televisions, refrigerators, etc.). Do not move the Wireless Weather Station while it is searching for the signal.
4. The time and date can be manually set. Once the signal is captured,
it will override any time and date set to the time zone selected.
5. Once the time and date are set, the indoor weather station will
conduct a search every night between midnight and 6:00 a.m and
correct to the accurate time and date (Daylight Saving Time is
automatic). If the signal has been received in the past 24 hours, the reception indicator will be displayed. After a successful reception, no more reception attempt would be made until the following day.

IV. Function Key Layout
A. The below picture shows the six function keys used in programming
and operation of your indoor weather station
V. Program Mode
The program mode is laid out in a manner that allows you to program each function separately, or you can follow the instructions entirely to p rog ram the Wireless Weather Station. Complete programming is usually done for the initial set-up, and will require you to skip step 1,2 and 3 of each programming section. The programming mode can be exited at any time by either pressing the “Snooze/CH” button, or waiting for the 15-second time-out to take effect.
