INTRODUCTION: 

The Wireless Forecast Station features radio-controlled time, date, forecast 

icons, indoor temperature and outdoor temperature on a stylish display.  

WIRELESS FORECAST STATION: 

SETUP INSTRUCTIONS STEP BY STEP: 

 Step 1: 

 Remove battery cover from the outdoor transmitter. 

 Slide the battery cover down and lift off the back of 

the transmitter 

 Insert 2 NEW AA batteries (not included) into the 

TX29U-IT transmitter. Observe the correct polarity. 

 Keep the Forecast Station and transmitter within 10 

feet during setup (15 minutes). 

Step 2:  

 Remove battery cover from Forecast Station: insert a solid object in the 

space provided at the upper-central position of the battery cover, then push 

down and pull out to remove the battery cover. 

 Insert 2 NEW AA batteries (not included) into the back of the Forecast 

Station. Observe the correct polarity (see marking inside the battery 

compartment).Do NOT mix old and new batteries.  

 The Forecast Station will display, time (12:00) and indoor temperature. 

 Within 3 minutes the Outdoor temperature should be displayed. 

Trouble shooting: 

 After 3 minutes, if the Outdoor temperature does not show up in the 

designated area on the Forecast Station, remove batteries from both units 

and start the setup process again. 

 For optimal reception performance, of the 915MHz signal, the outdoor 

transmitter should be placed within 330 feet (100 meters) from the Forecast 

Station.   

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 tower icon will show solid when the Forecast Station has received the 

WWVB signal. 

 No tower icon displayed. The Forecast Station was unable to receive a 

signal at this time. 

 Reposition the Forecast Station for better signal reception or try again at 

bedtime. 

Note: In case the Forecast Station is not able to detect the WWVB signal 

(disturbances, transmitting distance, etc.); the time can be manually set by 

following the Program Menu. 

FUNCTION BUTTONS: 

PROGRAM MENU:  

The forecaste station has four function buttons on the front. The SET button

WEATHER FORECAST ICONS: 

The weather forecasting feature is estimated to be 75% accurate. The 

weather forecast is based solely upon the change of air pressure over time. 

In areas where the weather is not affected by the change of air pressure, this 

feature will be less accurate. 

There are 3 possible weather forecast icons that will be displayed :   

Sunny

—indicates that the weather is expected to improve (not that the 

weather will be sunny). 

Sun with Clouds

—indicates that the weather is expected to be fair (not that 

the weather will be sunny with clouds). 

Clouds with Rain

—indicates that the weather is expected to get worse (not 

that the weather will be rainy). 

The weather icons change when the unit detects a change in air pressure. 

The icons change in order, from “sunny” to “partly sunny” to “cloudy” or the 

reverse. If the symbols do not change then the weather has not changed, or 

the change has been slow and gradual.  

Weather Tendency Arrows: 

These arrows reflect current changes in the air pressure.  

Up arrow: indicates air pressure is increasing, weather expected to 

improve or remain good.  

Down arrow: indicates air pressure is decreasing, weather is 

expected to become worse or remain poor.  

No arrow: No arrow means the pressure is stable. 

VIEW CHANNELS: 

The Forecast Station can receive up to 3 outdoor transmitters. Extra TX29U-

IT transmitters may be found online or at your retailer. Additional transmitters 

allow you to monitor remote temperature of up to 3 locations within a 330 Ft 

wireless range of the Forecast Station. 

Press and release the CH button to view a different channel.  A 

shift from one “boxed” number  to the next should be observed 

in the OUTDOOR LCD.  

Note: When only one transmitter is connected, you cannot see 

other channels and the channel indicator will not show. 

OUTDOOR TRANSMITTER RECEPTION ICON: 

 When the signal is successfully received from the outdoor transmitter, the 

icon will be solid.  

 The icon will flash when searching for the outdoor transmitter signal. 

 If reception is not successful, the icon will not be shown in LCD. 

MIN/MAX DATA: 

View Indoor MIN/MAX Data: Press and release the IN button to view the 

Minimum, Maximum and Current Indoor Temperatures and humidity records. 

The Time and Date will flash to show when the Minimum or Maximum 

Temperature occurred. 

Note: The indoor Humidity is not time and date stamped. 

Reset Indoor MIN/MAX Data:  

  Press and release the IN button to select the individual indoor Max or Min 

record you wish to reset.   

  Hold the SET button for five seconds.  The record is now reset to the
