INSTALLATION
The Meade Instruments Semi-professional weather station (TE827NLW) operates at 433MHz radio frequency, so no wire
installation is required between the main unit (receiver) and the remote weather sensors (transmitters).
The remote weather sensors include a thermo-hygrometer (temperature and humidity) sensor, anemometer (wind sensor) and a
rain gauge (rain sensor). All data measured by these remote sensors is transmitted to the main unit wirelessly, with the operating
range up to 328 feet (100 meters) in the open area.
The Anemometer and rain gauge must be placed outdoors to measure weather elements.
Remote thermo-hygrometers can be placed indoors or outdoors, depending on the location where the temperature and humidity
are to be measured. If you intend measuring outdoor temperature and humidity, place the remote sensor outdoors, preferably
not in direct sunlight.
Note:
It is critical to assemble and power up all of the remote weather sensors
BEFORE
setting up the main unit.
Note:
It is critical to power up and test communication between all of the weather sensors and the main unit
BEFORE
permanently mounting them outside.
BEFORE YOU BEGIN
• We recommend using alkaline batteries for the remote weather sensors and the main unit when temperatures are above
32°F (0°C). We recommend using lithium batteries for the remote weather sensors when temperatures are below 32°F (0°C).
• Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain correct power requirements).
• ALWAYS install batteries in the remote weather sensors before the main unit.
• Insert batteries before first use, matching the polarity in the battery compartment
• Remove protective plastic screen from LCD display (if any).
• During an initial setup, place the main unit close to the remote weather sensors.
• After reception is established (all of the remote readings will appear on the main unit’s display), position the remote sensors
and the main unit within the effective transmission range of up to 328 feet (100 meters). Ideally they should be placed within
the line of sight of the main unit. See placement tips in the user manual for each remote weather sensor separately.
• Transmission range may be affected by trees, metal structures and electronic appliances.
• The main unit must be placed indoors.
• The effective operating range may be influenced by the surrounding building materials and how the receiver (main unit) and
transmitters (weather sensors) are positioned.
• Place the remote weather sensors so that they face the main unit (receiver), minimizing obstructions such as doors, walls, and
furniture.
Note: When the temperature falls below freezing, the batteries in the outdoor remote weather sensors may have reduced
voltage supply and a shorter effective range. We recommend using lithium batteries at temperatures of 32°F (0°C)
and below.
IMPORTANT:
Make sure that the remote weather sensors are easily accessible for cleaning and maintenance.
We recommend cleaning the remote weather sensors periodically, as the dirt and debris may affect sensors accuracy.
