ABOUT WWVB (Radio Controlled Time)

The NIST (National Institute of Standards and Technology—Timeand Frequency Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time and date 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 Weather Station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The weather 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 is continually measuring every second, of every day, to an accuracy of ten billionths of a second per day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of aCesium-133atom in a vacuum. For more information on the atomic clock and WWVB please see the NIST website athttp://www.boulder.nist.gov/timefreq/stations/wwvb.htm.

QUICK SET-UPGUIDE

Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.

1.Have the indoor weather station, remote temperature/humidity sensor and wind speed sensor 3 to 5 feet apart.

2.Insert the telephone plug (RJ-11)from the wind speed sensor into the receptacle on the remote temperature/humidity sensor.

3.Batteries should be out of both the indoor weather station and remote temperature/humidity sensor units for 10 minutes.

4.Place the batteries into the remote temperature/humidity sensorfirst then into the indoor weather station.

5.DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.

In this time the indoor weather station and remote temperature/humidity sensor will start to talk to each other and the display will show the indoor temperature/humidity, outdoor temperature/humidity and wind speed. If the indoor weather station does not display all information after the 15 minutes please retry the set up as stated above. After all information has been displayed for 15 minutes you can place your sensors outdoors and set your time.

Important Notes on Set-upand Operation

The remote temperature/humidity sensor is both the source of power for both outdoor sensors and source of transmission for all remote sensor data.

The remote temperature/humidity sensor should be placed in a dry, shaded area.

Fog and mist will not harm your remote temperature/humidity sensor but direct rain must be avoided.

Direct rainfall will not harm the wind speed sensor.

The remote temperature/humidity sensor has a range of 300 feet. Any walls that the signal will have to pass through will reduce distance. An outdoor wall or window can have up to 30 feet of resistance and an interior wall can have up to 20 feet of resistance. Your distance plus resistance should not exceed 300 ft. in a straight line.

The remote temperature/humidity sensor transmits a signal every minute. After the batteries have been installed, the indoor weather station will search for the signal for a duration of 15 minutes. If there is no temperature or humidity reading in the OUTDOOR LCD or wind speed in the WIND SPEED LCD after 15 minutes, make sure the units are within range of each other, or repeat the battery installation procedure.

If a button is pressed before the indoor weather station receives the signal from the remote temperature/humidity sensor, you will need to follow the battery installation procedure again.

To complete the set up of your new wireless weather station after the 15 minutes have passed please follow the steps that follow in the Detailed Set-UpGuide.

DETAILED SET-UPGUIDE

BATTERY INSTALLATION

The first step to powering up the weather station is to insert the connector (RJ11) at the end of the wire attached to the wind speed sensor to the remote temperature/humidity sensor. Please ensure when doing this that the connector is inserted with the proper orientation. When seated properly you will hear the connector ‘click’ in place.

A.REMOTE TEMPERATURE/HUMIDITY SENSOR

1.Remove the mounting bracket and humidity hood.

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-upproblems make sure they do not spring free).

4.Replace the battery cover by sliding upwards. Be sure battery cover is on securely.

5.Replace the humidity hood.

B.INDOOR WEATHER STATION

1.Remove the battery cover. To do this, insert a solid object in the space provided at the lower-centralposition of the battery cover, then push up and pull out on the battery cover.

2.Observe the correct polarity, and install 3 AA batteries.

3.Replace the battery cover.

Note: Immediately after the batteries have been installed, the LCD (Liquid Crystal Display) will flash. Within 15 seconds the indoor temperature, indoor relative humidity, and the weather icons (sun and clouds) will be displayed. If not, remove batteries for 10 seconds and reinstall. If the outdoor temperature is not displayed within four minutes, remove batteries from both units, wait 30 seconds, and reinstall making sure to install batteries into the remote temperature sensor first. The time will show-:--and start searching for the WWVB signal. If it successfully receives the time signal (usually at night), it will display the correct time (defaulttime-zoneis Eastern). You will need to adjust the time zone to match your local time.

PROGRAM MODE

Programming Note: If 30 seconds are allowed to pass, or theWIND/SNZ button is pressed during the programming mode, the unit will confirm/set the last informationentered—thedisplay will stop flashing and return to normaltime-datereadings. If you don’t leave the program mode during the programming of sections IV through XI, you can advance to step 4 of the next program setting. If you do leave the program setting (or want to program a specific setting) follow each instructional step to program that setting.

VIII. TIME SETTING

There are two methods by which the time and date can be set:

A)Automatically via WWVB reception, or

B)Manually.

A. WWVB (Remote Control Time)

This method requires you to do nothing, except wait for the signal to be received, and to select a time zone. Reception usually takes approximately 10 minutes during optimal conditions. The best conditions for reception is at night, between midnight and 6:00 am—whenthere is less atmospheric interference. To keep your time as accurate as possible, the indoor weather station conducts a WWVB search every night between these hours, and overrides any manually set time. The WWVB tower icon (appearing in the TIME LCD) will flash when asignal-searchis in progress and a signal is being received, and will remain steady when the signal has been received. If the WWVB time has not been received after 10 minutes of battery installation, you may manually set the time or leave the time function alone (reception will occur regardless).

B. MANUAL TIME SETTING

Note: When in the12-hourformat “P.M.” will appear to the left of the hour in the time LCD between the hours of noon and midnight.

Note: Reception of the WWVB signal will automatically set the time. The reception of the signal will override any programmed time.

1.Press and hold the SET button for 5 seconds.

2. “LCD” will show in the TIME LCD and the number setting will flash. 3. Press and release the SET button five times.

4. The hours digits will flash in the TIME LCD.

5. Press and release the ALM/+ button to advance the hours.

6. Press and release the SET button to confirm the hours setting and advance to the minutes setting.

7. The minutes digits will flash in the TIME LCD.

8.Press and release the ALM/+ button to advance the minutes.

9.Press and release the SET button to confirm and advance to the year setting.

XII. SETTING THE FORECAST SENSITIVITY

Note: The forecast sensitivity can be adjusted to allow for areas that have a higher or lower sensitivity to changing air pressure (for example coastal areas have more pressure change than areas such as southern Arizona).

The numbers correspond to the amount of air pressure change necessary to trigger a change in the forecast icon. Areas that tend to have more air pressure change would set the sensitivity to 3, while areas that experience lower than normal air pressure change would set the sensitivity to 1.

1. Press and hold the SET button for 5 seconds.

2. “LCD” will show in the TIME LCD and the number setting will flash. 3. Press and release the SET button twelve times.

4. Either “1”, “2” or “3” will flash in the TIME LCD and the forecast icon and tendency arrows will flash in the FORECAST LCD.
