HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE STATION

natural_image
Technical line drawing of a mechanical device with no visible text or symbolsThe temperature station uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below:
- Insert finger or other solid object in the space at the bottom center of the battery compartment and lift up to remove the cover.
- Insert batteries observing the correct polarity (see marking).
- Replace compartment cover.
Note:
In the event of changing batteries in any of the units, all units need to be reset by following the setting up 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 temperature station in the first three minutes of power being supplied to it.
SETTING UP:
WHEN ONE TRANSMITTER IS USED
- First, insert the batteries in the transmitter (see "How to install and replace batteries in the temperature transmitter" above).
-
Within 2 minutes of powering up the transmitter, insert the batteries in the temperature station (see "How to install and replace batteries in the temperature station" above). Once the batteries are in place, all segments of the LCD will light up briefly. Following the indoor temperature and the time as 0:00 will be displayed. 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 the user may proceed to the next step.
-
After the batteries are inserted, the temperature station will start receiving data signal from the transmitter. The outdoor temperature data should then be displayed on the temperature station. If this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1.
- In order to ensure sufficient 868 MHz transmission however, the distance between the temperature station and the transmitter should not be more than 100 meters (see notes on "Positioning" and "868 MHz Reception").
Note:
In the event of changing batteries of the units, ensure the batteries 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.
WHEN MORE THAN ONE TRANSMITTER IS USED
- Remove all the batteries from the temperature station and transmitters, and wait 60 seconds.
- Insert the batteries in the first transmitter.
- Within 2 minutes of powering up the first transmitter, insert the batteries in the temperature station. Once the batteries are in place, all segments of the LCD will light up briefly. Following the indoor temperature and the time as 0:00 will be displayed. If this information is not displayed on the LCD after 60 seconds, remove the batteries from both units and wait for at least 60 seconds before reinserting them.
- The outdoor temperature data from the first transmitter (channel 1) should then be displayed on the temperature 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.
- Insert the batteries in the second transmitter as soon as the outdoor temperature readings from the first transmitter are displayed on the temperature station.
Note : Insert the batteries into the second transmitter within 45 seconds after the temperature station displays the information of the first transmitter.
- The outdoor temperature from the second transmitter and the "channel 2" icon should then be displayed on the temperature 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.
- Insert the batteries in the third transmitter as soon as the "channel 2" icon and outdoor data are displayed on the temperature 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, restart the setting up from step 1.
Note : Insert the batteries into the third transmitter within 45 seconds after the temperature station displays the information of the first transmitter or immediately after reception of the second transmitter is finished.
- In order to ensure sufficient 868 MHz transmission however, the distance between the temperature station and the transmitter should not be more than 100 meters (see notes on "Positioning" and "868 MHz Reception").
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 again the set-up from step 1.

(If not successful, the icon will not be shown on LCD). The user can then easily see whether the last reception was successful (icon on) or not (icon off). On the other hand, the short blinking of the icon shows that a reception is currently taking place.
12 OR 24 HOUR SETTING:
After the batteries are inserted, set the time display as follows:
- Press and hold the "SET/CHANNEL" button about 3 seconds to enter the set mode.
-
Either a “: 12h” or “: 24h” will appear on the LCD. If “: 12h” is displayed then the current time display is set to 12-hour time. If “: 24h” is displayed then the current time is set to 24-hour time.
-
To alternate between the two times display mode, simply press the "RESET/+/MIN/MAX" button.
- When the desired time display is selected, press the "SET/CHANNEL" button once more to enter the Time setting mode.
Note: When the time display is set as 12-hour mode, the temperature unit will be set to °F; when the time mode is in 24-hour format, the temperature unit will be set to °C.
TIME SETTING:
Following from the 12 or 24 hour setting mode.
-
The hour digit in the time section starts flashing
-
Using the "RESET/+/MIN/MAX" button, enter the hours of the current time and then followed by pressing the "SET/CHANNEL" button to move into the minutes mode
- Again, using the "RESET/+/MIN/MAX" button, enter the minutes of the current time (by holding the button down, the digits are incremented in steps of five) and then finally followed by pressing the "SET/CHANNEL" button to exit the setting mode. Your temperature Station is now fully operational.
MINIMUM AND MAXIMUM INDOOR AND OUTDOOR TEMPERATURE READING:
By pressing the "RESET/+/MIN/MAX" button the current indoor and outdoor temperature will alternate between the minimum, maximum and current temperature recordings. Once a new indoor and/or outdoor temperature high or is low reached, it will automatically be set into the temperature station's memory.
RESETTING THE MINIMUM AND MAXIMUM TEMPERATURE RECORDING:
By pressing and holding down the "RESET/+/MIN/MAX" button for about 3 seconds, both the indoor and outdoor minimum and maximum temperature recordings will be reset to the current indoor and outdoor temperatures. Only the outdoor temperature of the displayed transmitter will be reset. To reset the outdoor temperature of another transmitter move to the desired channel number.
OUTDOOR TEMPERATURE 1, 2, AND 3
If more than one transmitter is being used, to alternate between the temperature readings of transmitter 1, 2, and 3, simply press the "SET/CHANNEL" button. If the reading is from transmitter 1, then the identification numbers 1 will be displayed in the outdoor temperature section of the LCD. The same will apply to the next transmitter and so on. However, if only one transmitter is used, no identification number will be displayed on the LCD.
TEMPERATURE TRANSMITTER
The outdoor temperature is measured and transmitted every 4 seconds.
The range of the temperature transmitter may be affected by the temperature. At cold temperatures the transmitting distance may be decreased. Please bear this in mind when placing the transmitter.
868 MHz RECEPTION:
If the outdoor temperature data is not being received within three minutes after setting up (or outdoor display always show “- - . -” in the outdoor section of the temperature station during normal operation), please check the following points:
- The distance of the temperature station or transmitter should be at least 1.5 to 2 meters away from any interfering sources such as computer monitors or TV sets.
- Avoid placing the receiver onto or in the immediate proximity of metal window frames.
- Using other electrical products such as headphones or speakers operating on the same signal frequency (868MHz) may prevent correct signal transmission and reception.
- Neighbors using electrical devices operating on the 868 MHz signal frequency can also cause interference.
Note:
When the 868MHz signal is received correctly, do not re-open the battery covers of either the transmitter or temperature station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur.
The transmission range is about 100 m from the transmitter to the temperature station (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up).
POSITIONING THE TEMPERATURE STATION:
The temperature station has been designed for hanging on a wall or free standing.
