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.

THERMO-HYGROMETER SENSOR

FEATURES

• Remote data transmission to the main unit via 433 MHz signal

• 328 feet (100 meters) transmission range without interference

• LCD display of measured temperature and humidity

• Three (3) transmission channels selection

• Case can be wall mounted using built-in hanger

• Up to three T-H sensors per station are permitted

THERMO - SENSOR

A. LED INDICATOR

• Flashes once when the remote sensor transmits a reading to the main unit.

• Flashes twice when battery power is low.

B. BATTERY COMPARTMENT

Holds two AA-size batteries

C. RESET

Resets all readings

D. CHANNEL SWITCH

Selects the desired transmission channel from 1 to 3

E. WALL-MOUNT RECESSED OPENING

Attaches the remote sensor to the wall

Note: Install the batteries and select the channel before mounting the sensor. Battery installation

• Remove the screws from the battery compartment with a small Phillips screwdriver.

• Set the channel 1 through 3. The switch is located in the battery compartment. Channel 1 is typically selected if only one remote sensor is being used.

• Install 2 “AA” size alkaline batteries (not included) matching the polarities shown in the battery compartment.

• Replace the battery compartment door and secure the screws.

• Secure the thermo-hygrometer remote sensor in the desired location.

Mounting

• The remote thermo-hygrometer sensor can be placed on the flat surface or mounted on the wall in vertical position

• Use the wall mount hardware and screws provided when mounting the thermo-hygrometer sensor on the wall

Placement tips:

• The remote thermo-hygrometer sensor should be placed in the area with a free air circulation and sheltered from the direct sunlight and extreme weather conditions.

• Ideally, place the thermo-hygrometer sensor above the natural surfaces (such as a grassy lawn).

• Avoid placing the thermo-hygrometer sensor near sources of heat such as chimneys and heating elements.

• Avoid any areas collecting and radiating a heat from the sun, such as metal, brick or concrete structures, paving, patios and decks.

• The international standard for the valid air temperature measurements is 4 feet (1.25meters) above the ground.

Battery installation

• Unlock the funnel-shaped top on the rain gauge by turning both knobs on the sides in a Counter-clockwise direction.

• Remove the funnel-shaped top lifting it off the rain gauge bucket.

• Remove 7 small screws from the battery compartment cover using a small Phillips screwdriver

• Insert 2 “AA” size alkaline batteries (not included), matching the polarities as shown in the battery compartment.

• Replace the battery compartment door and secure the screws.

• Insert the funnel-shaped top into the rain gauge bucket and secure it into place by turning the knobs clockwise.

Mounting

• Make sure that the rain gauge bucket is level – check if the ball bearing inside the bucket is at the midpoint of the leveler.

• Place the protective screen over the top to protect the rain gauge from the debris.

• Mount the rain gauge in place using mounting hardware provided.

• Make sure that the rain gauge is in open area where precipitation falls directly into the gauge’s bucket, ideally 2-3 feet above the ground.

Placement tips

• The rain gauge should be placed in an open area away from walls, fences, trees and other coverings, which may reduce the amount of rain collected in the bucket. Additionally, trees and rooftops may be sources of pollen, leaves and other debris.

• To avoid rain shadow effects, place the rain gauge two to four times the height of any nearby obstruction.

• It is important that excess rain can flow freely away from the rain gauge.

Assembly

• With a flashlight, look into the mounting hole that will receive the anemometer axle shaft, on the back of the wind cups. Check that the set screw is backed off appropriately, not obstructing the opening.

• Place the wind cups over the axle shaft protruding from the anemometer housing and gently slide into place

• Insert the Allen wrench tool provided into the wind cups opening and tighten the small set screw inside

• Test to assure the wind cups are securely mounted on the anemometer shaft and spin freely
