INTRODUCTION
INSTALLATION
Thank you for selecting the Honeywell Black-Masked Weather Forecaster with
Heat Index. This device combines precise time keeping, monitoring and its
graphical display of heat index, temperature and humidity data from up to three
remote locations. Keep this manual handy as it contains practical instructions,
technical specifications and precautions. Included you will find:
• One User Manual
• One Quick Start Guide

AC adapter
The Honeywell Black-Masked Weather Forecaster with Heat Index TE657W
communications between the main unit (receiver) and the remote sensor
(transmitter) are wireless, thus simplifying the installation. The remote
temperature and humidity sensor transmits data to the main unit, with an
operating range of up to 200 feet (60 meters) in the open.
The remote temperature and humidity sensor can be placed indoors or
outdoors, depending on the area where the temperature and humidity are
intended to be measured. If you intend measuring outdoor temperature and
humidity, place the remote sensor outdoors.
NOTE: It is critical to power the remote sensor BEFORE setting up the main
unit.
NOTE: It is critical to power up and test communication between the remote
sensor and the main unit BEFORE permanently mounting it outside.

BEFORE YOU BEGIN
REMOTE TEMPERATURE & HUMIDITY SENSOR
• We recommend using alkaline batteries for the remote sensor and the
main unit. When outdoor temperatures are 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
• Remove protective plastic screen from LCD display (if any)
• 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 200 feet (60 meters). Ideally the
remote sensor should be placed within the line of sight from the main
unit.
• Transmission/reception range may be affected by trees, metal
structures, electronic appliances, surrounding building materials, main

• Remote data transmission to the main unit via 433 MHz frequency
• LCD displays temperature, humidity and channel
• Selection of the temperature display in Celsius or Fahrenheit
• Three transmission channels
• Case can be wall mounted using built-in hanger

unit location and transmitter (remote sensor) positioned.
• The main unit must be placed indoors.
• Place the remote sensor so that it faces the main unit (receiver),
minimizing obstructions such as doors, walls and furniture.
NOTE: Battery voltage levels in the outdoor sensor may drop with below
freezing temperatures, this may reduce the transmission range. For optimum
performance, at temperatures below 32°F (0°C) We recommend lithium
batteries.

• Selects the temperature display in Fahrenheit or Celsius
• Avoid placing the thermo-hygrometer sensor near sources of heat,
NOTE: Install the batteries; select the channel and temperature in °C or °F
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
• Select the temperature unit by pressing °C/°F switch with a paper clip
or similar tool
• Replace the battery compartment door and secure the screws
• Secure the remote sensor in the desired location
MOUNTING
• The remote thermo-hygrometer sensor can be placed on the flat
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 correctly installed, the remote sensor will start
transmitting a temperature and humidity data to the main unit.
MAIN UNIT
The main unit measures pressure, indoor temperature, humidity, calculates
heat index. It also receives atomic time data from the US WWVB Atomic Clock
and readings from up to three remote sensors. It should be placed indoors.
FEATURES
Time
• Precise time and date set via signals from the US Atomic clock
surface or mounted on the wall in vertical position
• Use a screw, rather than a nail, for best mounting of the sensor
• When mounting the main unit on the wall or vertical surface, fold the
table stand back into the unit.
PLACEMENT
• The remote thermo-hygrometer sensor should be placed under eaves
or a similar location with free air circulation yet sheltered from direct
sunlight and extreme weather
• Ideally, place the thermo-hygrometer sensor over soil, rather than
asphalt which would cause false readings.
7
• 12 or 24 hour time format
• Manual adjustment of time and date
• Calendar date with month and day in 6 languages English, German,
French, Italian, Spanish and Dutch
• Sunrise/set calculation for over 100 pre-programmed cities based
on geographical information entered by the user
• Moon Phase calendar and historical data for days
• Dual crescendo alarms with snooze
• Programmable Ice Warning Alarm

• Ideally the remote weather sensors should be mounted within the line
Weather
• Weather forecast for the next 12 to 24 hour in seven large icons:
Sunny, Slightly Cloudy, Cloudy, Light Rainy, Heavy Rainy, Light
Snowy, Heavy Snowy and Stormy
• Barometric pressure in imperial or metric units
• Altitude adjustment for pressure compensation
• 24 hour barometric pressure history chart
• User-defined High/Low Temperature alarm
• Indoor/Outdoor Temperature & Humidity in up to 3 remote locations
(additional sensors required)
• Comfort level indicators (Dry, Humid, etc)
• Heat Index and level measurements
• Operating range of up to 200 feet (60 meters)
Power
• 4 AA batteries (main unit)
• 2 AA batteries (remote sensor)
BATTERY INSTALLATION
of sight of the main unit.
• Transmission range may be affected by trees, metal structures and
electronic appliances.
• Test reception before permanently mounting all the remote weather
sensors.
Avoid placing the main unit in the following areas:
• Direct sunlight and surfaces emitting and radiating heat, such as
heating ducts or air conditioners.
• Areas with interference from wireless devices (cordless phones, radio
headsets, baby monitoring devices and other electronics.)
OPERATION
Once the main unit is powered, the display will show all available LCD
segments for a moment.
IMPORTANT: All of the display functions will be locked, allowing setting your
local altitude and pressure parameters by pressing the UP (+) or DOWN (--)
and SET buttons. The locked display will show the pressure icon and
abbreviation “inHg” flashing in the Pressure Window, default time in Clock
• Remove the battery compartment door located on the back of the main
unit.
• Insert four (4) AA size batteries according to the polarities shown and
replace the battery compartment door.
• When placing the main unit on the table or other horizontal surface,
unfold the table stand for the desired viewing angle.
PLACEMENT
• Make sure that the main unit is locating within the operating range of all
remote weather sensors.
