Thermo-Hygro Transmitter
SETTING UP
WHEN ONE TRANSMITTER IS USED
1. First, insert the batteries in the tr ansmitter (see “How to install and replace batteries in the Thermo-hygro outdoor transmitter” on
page 11).
2. Within 2 minutes of powering up the transmitter, insert the batteries
Remote transmissio n of outdoor
temperature and humidity to weather station by 915 MHz signals
Alternate display of temperature and
humidity display
Water-resistant casing
Wall mounting case. (Mount in a sheltered
place. Avoid direct rain and sunshine)

in the Weather S tation (see “How to install and replace batteries in the Weather Station ” on pages 11-12). Once the batteries are in place, all segments of the LCD will light up briefly and a short signal tone will sound. Next the indoor temperature/humidity is displayed and the time reads 12:00. If this information is not displayed on the LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them. Once the indoor data is displayed you may proceed to the next step.
3. After the batteries are inserted, the Weather station will start receiving data signal from the transmitter. The outdoor temperature and humidity data should then be displayed on If this does not happen after 2 minutes, remove the batteries from both units, and then restart the process from step 1.
4. The distance between the Weather Station and the transmitter should not be more than 330 feet to ensure sufficient 915 MHz transmission. (See notes on “Po sitioning” and “915 MHz
Reception”). Note:

the Weather station.
When changing batteries, ensure that they do not spring free from the contacts. Always wait at least 1 minute after removing the batteries before reinserting, otherwise start up and transmission problems may occur. Please note that initial set up of the weather station should be with the sensor(s) within 5 feet of the display for 15 minutes. Once connection is established and locked in for 15 minutes the sensors can be moved, but not more than 330 ft (open air) from the display.
WHEN MORE THAN ONE TRANSMITTER IS USED
1. User shall remove all the batteries from the Weather Station and transmitters, and wait 60 seconds.
2. Insert the batteries in the first transmitter.
3. Within 2 minutes of powering up the first transmitter, insert the batteries in the Weather Station. Once the batteries are in segments of the LCD will light up briefly and a short signal tone will sound. Next the indoor temperature/humidity is displayed and the time reads 12:00. If this information is not displayed on the LCD
8
place, all
after 60 seconds, remove the batteries from both units and w ait for at least 60 seconds before reinserting them.
4. The outdoor temperature and humidity data from the first transmitter (channel 1) and the signal reception icon should be displayed on the Weather Station. If this does not happen after 2 minutes, remove the batteries from both units, and then restart the process from st ep 1.
5. Insert the batteries in the second transmitter as soon as the signal reception icon and outdoor data are displayed on the Weather Station. Then within 2 minutes, the channel 2 outdoor data from the second transmitter and the "channel 2" icon should be displayed on the Weather Station. If this does not happen after 2 minutes, remove the batteries from both units, and then restart the process from step 1.
You must insert the batteries into the second transmitter
Note :
within 45 seconds after the Weather Station displays the information of the first transmitter.
9
6. Insert the batteries in the third transmitter as soon as the "channel 2" icon and outdoor data are displayed on the Weather Station. Then within 2 minutes, the channel 3 outdoor data from the third transmitter will be displayed and the channel icon will shift back to "1" once the third transmitter is successfully received. If this does not happen after 2 minutes, remove the batteries from both units, and then restart the process from step 1.
: You must inser t the batteries into the third transmitter within
Note
45 seconds after the Weather Station displays the information of the first transmitter - or immediately after reception of the second transmitter is fini shed.
7. The distance between the Weather Station and the transmitter should not be more than 330 feet to ensure sufficient 915 MHz transmission. (See notes on “Po sitioning” and “915 MHz
Reception”).
IMPORTANT:
Transmission problems will arise if the setup for additional sensors is not followed as described above. Should transmission problems occur, it is
10
necessary to remove the batteries from all units and start again the set-up from step 1.
Note:
If the 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.
When the weather station is receiving the WWVB time signal, the
outdoor transmitter data signal will temporarily not be received by the weather station. During this short period of time, the outdoor readings shown on the weather station will not be renewed until the WWVB time signal is successfully received.
TO INSTALL AND REPLACE BATTERIES IN THE THERMO­HYGRO TRANSMITTER
The Thermo-Hygro Transmitter uses 2 x AA, IEC, LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below:
1. Remove the cover.
2. Insert the batteries, observing the correct polarity (see marking).
11
3. Replace the battery cover.
Note:
When changing batteries in any of the units, all units need to be reset by following the setup procedures. This is due to a random security code assigned by the transmitter at start-up. This code must be received and stored by the Weather Station in the first 3 minutes of powe r being supplied to the transm itter.
TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The Weather Station uses 2 x C, IEC LR14 1.5V batteries. To install and replace the batteries, please follow the steps below:
1. Insert finger or other solid object in the space at the bottom center of the battery compartment and lift up to remove the cover.
12
2. Insert batte ries observing the correct polarity (see marking).
3. Replace compartment cover.
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 depot.

RESET
The Weather Station and the Thermo-hygro transmitter need to be reset when one of the following conditions occur:
Unsuccessful 915 MHz signa l reception.  Malfunction on the units.  Battery replacement.
To perform a reset, remove all batteries from the units. Wait for at least 1 minute before powering up the Weather stati on again. Procee d from step 1 in “Setting Up”.
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 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 projection station. However, due to the nature of the Earth’s Ionosphere, reception is very
14
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 Cesium­133 atom in a vacuum. For more detail, visit http://www.boulder.nist.gov/timefreq.htm. To listen to the NIST time, call (303)499-7111. This number will connect you to an automated time, announced at the top of the minute in “Coordinated Universal Time”, which is also known as Greenwich Mean Time (GMT). This time does not follow Daylight Saving Time changes. After the top of the minute, a tone will sound for every second. It is possible that your wireless weather station may not be exactly on the second due to the variance in the quartz. However, the clock will adjust the quartz timing over the course of several days to be ver y accurate; under 0.10 seconds per day.
