WEATHER STATION

USER’S MANUAL

INTRODUCTION

Thank you for purchasing General’s Data Logging Wireless

Weather Station. This compact and easy-to-use product

uniquely measures and monitors weather data right at

your immediate location.

It includes a wide range of weather features plus precise

atomic time and perpetual calendar. Weather

measurements include: air temperature, relative humidity,

barometric pressure, wind speed and direction,

rainfall levels and more.

PACKAGE CONTENTS

In this package you will find:

• One Main Unit (receiver)

• One Rain Gauge (remote rain sensor/transmitter)

• One Anemometer (remote wind sensor/transmitter)

• Two Three-Channel Temperature & Humidity Sensor (transmitter)

• One 7.5V AC/DC Adapter

• One CD-ROM disk

• One 6 ft (2m) USB cable

• Mounting Hardware with wrench tool

• One User’s Manual

Required for installation (not included)

- Small Phillips screwdriver

- Anemometer mounting pole

- Small paper clip to reset sensors

NOTE

: If any items are missing or damaged, please contact Customer Service before proceeding with

installation.

INSTALLATION

General’s Wireless Data Logging Weather Station 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 (2) thermo-hygrometer (temperature and humidity) sensors,

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 a rain gauge must be placed outdoors to measure weather elements.

Remote thermo-hygrometers can be placed indoors or outdoors. If you intend measuring outdoor

temperature and humidity, place the remote sensor outdoors, preferably not in the direct sunlight.

BEFORE YOU BEGIN

The components of this complete Wireless Weather Station operate wirelessly at 433MHz radio

frequency.

No interconnecting wires are required between the main unit (receiver) and the remote sensors

(transmitters). Power up and test communications between all of the sensors and the main unit

BEFORE mounting them outside.

• For most applications alkaline batteries are acceptable where temperatures remain above 32°F

(0°C).

• Avoid using rechargeable batteries. (Rechargeable batteries do not provide correct power levels).

• ALWAYS install batteries in the remote sensors before the main unit.

• Insert batteries matching the polarity in the battery compartment.

• Remove plastic sleeve from LCD display (if any).

• During an initial setup, place the main unit close to the remote 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 sensor.

• 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 (sensors) are positioned.

• Place the remote sensors so that they face the main unit (receiver), minimizing obstructions such as

doors, walls, and furniture.

• Make sure that the remote sensors are easily accessible for cleaning and maintenance.

NOTE

: When the temperature falls below freezing, the outdoor sensor batteries may have reduced

voltage and a reduced effective range. We recommend using lithium batteries at temperatures

below 32°F (0°C).

IMPORTANT: We recommend cleaning the remote sensors periodically, as dirt and debris affects sensor

accuracy.

THERMO-HYGROMETER SENSOR

FEATURES

• LCD display of measured temperature and humidity.

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

• 328 feet (100 meters) transmission range without interference.

• Three (3) transmission channels selection.

• Case can be wall mounted using built-in hanger.

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 2 “AA” batteries. (not included)

C. RESET

• Resets all readings (requires small

paper clip.)

D. CHANNEL SWITCH

• Selects the desired sensor channel from

1 to 3.

E. WALL-MOUNT RECESSED OPENING

• Keeps the remote sensor on 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. Set one sensor to Channel 1 and the second sensor to Channel 2, etc. The sensors must operate on separatechannels. • Install 2 “AA” batteries matching the polarities shown in the battery compartment. • Replace the battery compartment door and secure the screws.
PAGE 3
DISPLAY • Light sensor detects low light conditions and LCD lights up automatically when adapter is connected. POWER • Open the battery compartment door on the back of the main unit. • Insert four (4) “AA” batteries according to the polarities shown and replace the battery compartment door. • Connect 7.5V AC/DC adapter provided to the main display unit and plug into the wall power outlet. NOTE: The AC/DC adaptor connection is required for automatic backlight control.

CUSTOM WEATHER STATION SETTINGS The basic operation of your weather station has been designed to work right out of the box, 10 minutes after power is provided to the main unit. To use your station, you will have to complete the steps identified under INITIAL SETUP while this section of the manual will provide you with additional operational details and suggestions for custom settings and alarms including: • The time alarms (Clock and Alarm Window). • The temperature alerts (Temperature and Humidity Window).

NOTE: Alarm will automatically “snooze” if no buttons are pressed after the alarm sounds for 2 minutes. This will occur three times only. DISABLE ALARM(S): Press ALARM/CHART to disable the alarm (s). NOTE: For weekday alarm, pressing ALARM/CHART will only disable the alarm for the current day. The alarm will activate again on the next day, Monday through Friday. ATOMIC TIME RECEPTION The purpose of the atomic clock is to provide consistently accurate time and date automatically.
