TE688W

Wireless Weather Forecaster with

Indoor/ Outdoor Temperature and Humidity

USER MANUAL

INTRODUCTION

Thank you for selecting a Meade Instruments Weather Forecaster. This device combines precise time keeping, monitoring and displaying of current temperature and humidity data from up to three remote locations.

Meade Instruments is the world’s leading designer and manufacturer of telescopes for professional and amateur astronomers – famous for its innovative, high performance telescopes at affordable prices. Meade Instruments now brings that same passion for innovation and high performance to its own line of precision, feature rich weather stations.

Please read this instruction manual so that you can get the most enjoyment out of your Meade Instruments weather station.

In this package, you will find:

• One (1) main unit (receiver)

• One (1) remote sensor (transmitter)

• One (1) user manual

Please keep this manual handy as it contains practical instructions, technical specifications and precautions.

INSTALLATION

Communication between the main unit (receiver) and the remote sensor (transmitter) is wireless. This allows you to greater flexibility in choosing the location of remote sensor. The remote transmits data up to 100 feet (30 meters) over an open, unobstructed area.

The remote sensor can be located either indoors or outdoors, allowing you chose where your data is obtained.

NOTE:

• It is critical to power the remote sensor BEFORE setting up

the main unit.

• It is critical to power up and test communication between the remote sensor and the main unit BEFORE permanently mounting if outside.

BEFORE YOU BEGIN

• We recommend using alkaline batteries for the remote sensor and the main unit. If outdoor temperatures regularly fall below

32°F (0°C), we recommend using lithium batteries.

• Avoid using rechargeable batteries. (Rechargeable batteries

cannot maintain correct power requirements.)

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

• Insert batteries before first use, matching the polarity in the battery compartment.

• Press RESET after each battery change with a paper clip or similar tool.

• During initial set up, place the remote sensor close to the main unit.

• After reception is established (remote readings will appear on the main unit’s display), position the remote sensor and the main unit within the effective transmission range of up to 100 feet (30 meters).

• The main unit must be placed indoors.

NOTE:

• Avoid pressing any buttons on the main unit before the remote

readings are displayed.

• Transmission or reception range may be affected by trees, metal structures, electronic appliances, surrounding building materials and how the main unit and transmitter are positioned.

• Place the remote sensor so that it faces the main unit (receiver), minimizing obstructions such as doors, walls and furniture.

• Though the remote sensors are weather-resistant, they should be placed away from direct sunlight, rain or snow. The optimal location for the remote sensor outdoors is under the eaves on the north side of the building.

REMOTE TEMPERATURE AND HUMIDITY SENSOR (TS23C)

FEATURES

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

• Three transmission channels

• Case can be wall mounted using built-in hanger

A. LED INDICATOR

• Flashes once about every 45 seconds with each transmission to

the main unit.

• Flashes twice when battery power is low.

B. BATTERY COMPARTMENT

• Holds two AA-size batteries C. RESET

• Resets all previous settings

D. CHANNEL SWITCH

• Selects the desired channel: 1, 2 or 3

E. WALL-MOUNT RECESSED OPENING

• Mounts the remote sensor on the wall

BATTERY INSTALLATION

NOTE: When the temperature falls below freezing point 32°F (0°C), battery voltage will drop which may result in reduced the transmission range. For optimum performance in cold weather conditions, we recommend using lithium batteries. NOTE: Install the batteries and select the channel before mounting the remote sensor.

• Remove the screws from the battery compartment with a small

Phillips screwdriver (not included).

• 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 remote sensor in the desired location.

MOUNTING

• The remote sensor can be mounted either horizontally or vertically.

• Use a screw, rather than a nail, to securely mount the sensor.

• When mounting the main unit on a vertical surface, fold the

built-in table stand back into the unit, allowing the main unit to lie flush with the surface.

PLACEMENT

• The remote sensor should be placed under eaves or a similar location with free air circulation sheltered from direct sunlight and extreme weather.

• Ideally, place the remote sensor over soil, rather than asphalt which would cause false readings.

• Avoid placing the remote sensor near sources of heat, such as chimneys and heating elements

• Avoid areas that collect heat from the sun and radiate heat, such as metal, brick or concrete structures, paving, and patios

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

OPERATION

Immediately after batteries are installed, the remote sensor will start transmitting a temperature and humidity data to the main unit.

MAIN UNIT

The main unit measures indoor temperature and humidity readings and temperature and humidity from up to three remote sensors location (outside or inside). Its clock receives atomic time data from the US WWVB Atomic Clock.

FEATURES

TIME

• Precise time and date set via signals from the US Atomic clock

• 12 or 24 hour time format

• Manual adjustment of time and date

• Calendar date with month and day in 7 languages English,

German, French, Italian, Spanish, Dutch and Swedish

• Dual crescendo alarms with snooze

• Programmable ice warning alarm

WEATHER

• Weather forecast for the next 12 to 24 hour in seven large icons: sunny, slightly cloudy, cloudy, rainy, heavy rainy, snowy and heavy snowy.

• Programmable minimum/maximum temperature alarm

• Indoor/outdoor temperature and humidity in up to 3 remote

locations (additional sensors required)

• Barometric pressure in imperial or metric units

• Altitude adjustment for pressure compensation

• 24 hour barometric pressure history chart

• Comfort level indicators (Dry, Humid, etc)
