QUICK SET-UP GUIDE

Hint: Use good quality Alkaline Batteries and avoid

rechargeable batteries.

1. Have the intelligent weather station and remote

temperature/humidity sensor 3 to 5 feet apart.

2. Batteries should be out of both the intelligent weather station and

remote temperature/humidity sensor units for 10 minutes.

3. Place the batteries into the remote temperature/humidity

sensor first and then into the intelligent weather station.

4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.

In this time the intelligent weather station and remote

temperature/humidity sensor will begin to communicate with each other

and the display will show the temperature/humidity, outdoor

temperature/humidity. If the intelligent 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-up and Operation

•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.

•The remote temperature sensor should be placed in a dry,

shaded area. The remote temperature 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 receiver 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 foot

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.

•The remote temperature/humidity sensor transmits a signal every

4 seconds – with variations during updating periods. After the

batteries have been installed, the intelligent weather station will

search for the signal for the duration of 45 seconds. If there is no

temperature or humidity reading in the OUTDOOR LCD after 5

minutes, make sure the units are within range of each other, or

repeat the battery installation procedure.

•If a button is pressed before the intelligent 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 intelligent weather station

after the 5 minutes have passed, please follow the steps in the “Manual

Settings” section.

Note:

If the outdoor transmitter signal reception is not successful on the first

frequency of 915MHz for 45 seconds, the frequency is changed to

920MHz, and the learning is tried for another 45 seconds. If it is still not

successful the reception is tried for 45 seconds on 910MHz. This will

also be done during re-synchronization.

BATTERY INSTALLATION

INTELLIGENT WEATHER STATION

The intelligent weather station uses 3 x

AA (alkaline recommended) batteries.

When the batteries need to be

replaced the low battery symbol will

appear on the LCD (or replace the

batteries annually). To install and

replace the batteries, please follow the

steps below:

1. Remove the cover.

2. Insert batteries observing the

correct polarity (see battery

compartment marking).

3. Replace battery cover.

REMOTE TEMPERATURE/HUMIDITY SENSOR

The remote temperature/humidity sensor uses 2 x AA

(alkaline recommended) batteries. To install and

replace the batteries, please follow the steps below:

1. Remove the battery cover at the front side with a

small screwdriver.

2. Insert the batteries, observing the correct polarity

(see battery compartment marking).

3. Replace the battery cover on the unit.

Note:

When changing the batteries in any of the units, all units need to be

reset by following the “Quick Set Up Guide” procedures. This is because

a random security code is assigned by the transmitter at start-up, and

this code must be received and stored by the intelligent weather station

in the first few minutes of power being supplied to it.

BATTERY CHANGE:

It is recommended to replace the batteries in all units on an annual

basis to ensure optimum accuracy of these units.

Please participate in the preservation of the environment.

Return used batteries to an authorized facility.

ABOUT WWVB (Radio Controlled Time)

The NIST (National Institute of Standards and Technology—Time and

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 intelligent

weather station. However, due to the nature of the Earth’s Ionosphere,

reception is very limited during daylight hours. The intelligent 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 a Cesium-133 atom

in a vacuum. For more information on the atomic clock and WWVB

please see the NIST website at

http://www.boulder.nist.gov/timefreq/stations/wwvb.htm.

*When the signal from the remote temperature/humidity sensor is

successfully received by the intelligent weather station, this signal

reception will be switched on. (If not successful, the icon will not be

shown on LCD) So the user can easily see whether the last reception is

successful (icon on) or not (icon off). On the other hand, the short

blinking of the icon shows that reception is currently taking place.
