The Outdoor Temperature Transmitter (TX29U-IT)

 Remote transmission of outdoor temperature to Weather

Station by 915 MHz

 Water resistant casing  Wall mounting case (Mounting at a sheltered place. Avoid

direct rain and sunshine)

Note:

Sensor must be outside to transmit outdoor temperature.

The sensor reads data from the environment it is currently in.

SETTING UP:

When one transmitter is used

1. First, insert the batteries into the Temperature transmitter (see “Install and replace batteries in the Temperature transmitter“).

2. Immediately after and within 30 seconds, insert the batteries into Weather station (see “Install and replace batteries in the Weather station”). Once the batteries are in place, all segments of the LCD will light up briefly. Next, the time shows 12:00 and the "Weather girl" icon will be displayed. If these are not displayed after 60 seconds, remove the batteries and wait for at least 10 seconds before reinserting them.

3. After inserting the batteries, the Weather station will start receiving data from the transmitter. The outdoor temperature and the signal reception icon should then be

displayed on the Weather station. If this does not happen after 3 minutes, the batteries will need to be removed from both units and reset from step 1.

4. In order to ensure sufficient 915 MHz transmission however, this should under good conditions be a distance no more than 330 feet (100 meters) in open air between the final position of the Weather Station and the transmitter (see notes on “Positioning” and “915 MHz Reception”).

5. Once the remote temperature has been received and displayed on the Weather station, the WWVB time (radio controlled time) code reception is automatically started. This takes typically between 3-5 minutes in good conditions. If after 10 minutes, the WWVB time has not been received, press the SET key to manually enter a time initially.

When more than one transmitter is used

1. User shall remove all the batteries from the Weather Station and transmitters and wait for 60 seconds if setting has been done with one transmitter before.

2. Insert the batteries to the first transmitter.

3. Within 30 seconds of powering up the first transmitter, insert the batteries to the Weather Station. Once the batteries are in place, all segments of the LCD will light up briefly. Following this, the time (shown as 12:00) and the weather girl icon will be displayed. If they are not shown in the LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them.

4. The outdoor temperature from the first transmitter (channel 1) should then be displayed on the Weather station. Also, the signal reception icon will be displayed. If

this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1.

5. Insert the batteries to the second transmitter as soon as the outdoor temperature readings from the first transmitter are displayed on the Weather station.

Note: User must insert the batteries into the second transmitter within 10 seconds of reception of the first transmitter.

6. The outdoor data from the second transmitter and the "channel 2" icon should then be displayed on the Weather station. If this does not happen after 2 minutes, the batteries will need to be removed from all the units and reset from step 1.

7. Insert the batteries in the third transmitter as soon as the "channel 2" icon and outdoor data are displayed on the Weather station. Within 2 minutes, the channel 3 outdoor data from the third transmitter will be displayed and the channel icon will shift back to "1". If this does not happen, you must restart from step 1.

Note: User must insert the batteries into the third transmitter within 10 seconds of reception of the second transmitter.

8. In order to ensure sufficient 915 MHz transmission however, this should under good conditions be a distance no more than 330 feet (100 meters) in open air between the final position of the Weather Station and the transmitter (see notes on “Positioning” and “915 MHz Reception”).

9. Once the remote temperature has been received and displayed on the Weather station, the WWVB time (radio controlled time) code reception is automatically started. This takes typically between 6-8 minutes in good conditions.

IMPORTANT:

Transmission problems will arise if the setting for additional sensors is not followed as described above. Should transmission problems occur, it is necessary to remove the batteries from all units and start the setup again from step 1.

Note: Daily WWVB reception (Atomic time) is attempted at the top of each hour between 12:00 am to 6:00 am. If the reception is successful, there is no reception attempt until the following day. When this is successful, the received time will override the manually set time. The date is also updated with the received time. (Please also refer to the notes on “WWVB Radio Controlled time” and “Manual Time Setting”)

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 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 Wireless Weather Station. However, due to the nature of the Earth’s ionosphere, reception is very limited during daylight hours. The Wireless Weather Station will search for a signal every night when reception is best. The WWVB radio station receives the time data 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. This atomic clock regulates the WWVB transmitter.

Note: If the WWVB tower icon flashes on the top left of the LCD, but does not set the time or the tower does not appear at all, then please note the following:

 Recommended distance from any interfering sources like computer monitors or TV

sets is a minimum of 6 feet (2 meters).

 With ferro-concrete rooms (basements, superstructures), the received signal is

naturally weakened. In extreme cases, please place the unit close to a window and/ or point its front or back towards the Fort Collins, Colorado transmitter.

 During nighttime, the atmospheric disturbances are usually less severe and reception

is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.

 In case the Weather Station is not able to detect the WWVB-signal (disturbances,

transmitting distance, etc.), the time can be manually set (please refer to the notes on

Manual time setting).

INSTALL OR REPLACE BATTERIES IN THE WEATHER STATION

The Weather Station uses 2 x AA, IEC LR6, 1.5V batteries. To install or replace the batteries, please follow the steps below:

1. Remove the cover at the back of the Weather Station.

2. Insert batteries observing the correct polarity (see marking).

3. Replace compartment cover.

code is assigned by the transmitter at start-up and this code must be received and stored by the Weather station in the first 3 minutes of power being supplied to it.

BATTERY CHANGE:

It is recommended to replace the batteries in all units regularly to ensure optimum accuracy of these units (Battery life See Specifications below).

The Temperature Transmitter uses 2 x AA, IEC LR6 and a 1.5V battery. To install or replace the batteries, please follow the steps below:

1. Remove the battery compartment cover at the back of the transmitter.

2. Insert the batteries, observing the correct polarity (see marking).

3. Replace the battery compartment cover on the unit.

Note:

When changing batteries in any of the units, all units need to be reset by following the setup procedures. This is because a random security
