INTRODUCTION
Thank you for selecting the Honeywell Temperature and Humidity
Sensor with LCD. This device register, display and transmits
temperature and humidity from the remote location to the designated
main unit (receiver).
In this package you will find:
•One remote sensor (transmitter) TS33C
•One User Manual
Please keep this manual handy as you use your new item. It contains
practical step-by-step instructions, as well as technical specifications
and precautions you should know.

WIRELESS WEATHER STATIONS
BEFORE YOU BEGIN
•The remote sensor can be placed indoors or outdoors.
•We recommend using alkaline batteries for the remote sensor
when temperatures are above 32°F (0°C). We recommend using
AA lithium batteries when temperatures are below 32°F (0°C).
•Avoid using rechargeable batteries. (Rechargeable batteries
cannot maintain correct power requirements).
•Insert batteries before first use, matching the polarity in the
battery compartment.
•ALWAYS install batteries in the remote sensor before the main
unit.
•Press RESET after each battery change with a paper clip or
similar tool.
•During an initial setup, place the main unit as close as possible
6
to the remote sensor.
•After reception is established (the remote temperature and
humidity will appear on the main unit’s display), position the
remote sensor and the main unit within the effective
transmission range of 100 feet (30 meters).
NOTE:
1. Avoid setting manually the time and date on the main unit before the
remote reading is displayed.
2. The effective operating range may be influenced by the surrounding
building materials and how the receiver (main unit) and transmitter
(remote sensor) are positioned.
3. Place the remote sensor so that it faces the main unit (receiver),
minimizing obstructions such as doors, walls, and furniture.
4. Though the remote sensors are weather-resistant, they should be
placed away from direct sunlight, rain or snow.
NOTE: When the temperature falls below freezing, the batteries in
the outdoor remote sensors may have reduced voltage supply and a
shorter effective range. We recommend using lithium batteries at
temperature 32°F (0°C) and below.

BATTERY INSTALLATION
NOTE: Install the batteries; select the channel and temperature in
C° or F° before mounting the remote sensor.
•Remove the screws from the battery compartment with a small
Phillips screwdriver.
•Set the channel. 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 remote sensor in the desired location.
LOW BATTERY WARNING
A low-battery indicator [ ] will appear on the remote temperature
and humidity reading line of the main unit, warning that the remote
sensor batteries need replacement.
PLACEMENT OF THE REMOTE SENSOR
The remote sensor can be mounted on the wall using the recessed screw
hole or placed on a flat surface indoors or outdoors.
8
GETTING STARTED
After batteries are installed; remote sensor will transmit temperature
and humidity readings at 45 second intervals.
The main unit may take up to two minutes to receive the initial readings.
Upon successful reception, remote temperature and humidity will
appear on the main unit’s display. The main unit will automatically
update readings at 45-second intervals.
LOST COMMUNICATION
If the main unit display line for the remote sensor reading goes blank,
refer to the main unit’s User Manual to find out the way to begin a new
signal search. If the signal still isn’t received, please make sure that:
•The remote sensor is in its proper location.
•The distance between main unit and remote sensor is not over
100 feet (30meters).
•The path between units is clear of obstacles. Shorten the
distance if necessary.
•Fresh batteries are installed correctly in both remote sensor and
main unit.
If there is no reception, please perform the following steps:
•Bring the main unit and remote sensor close together.
•Remove four (4) small screws from the back of the remote
sensor with small Phillips screwdriver, and open the battery
compartment.
•Remove the batteries from the battery compartment and reinstall
them in the same manner. Remote sensor LED indicator will
flash showing transmission of the signal.

9 9
•Remove the batteries from the main unit and reinstall them in
the same manner.
•The remote temperature and humidity appeared on the main
unit’s display will show that transmission is being received
successfully.
TRANSMISSION COLLISION
Signals from the other household devices such as wireless doorbells,
home security systems, and entry control, may interfere with this
product or cause temporary reception interruption. This is normal and
will not affect the general performance of the product. The transmission
and reception of the temperature and humidity readings will resume
once the interference subsides.
PRECAUTIONS
This product is engineered to give you years of satisfactory service if
handled carefully. Here are a few precautions:
•Do not immerse the unit in water.
•Do not clean the unit with abrasive or corrosive materials. They
may scratch the plastic parts and corrode the electronic circuits.
•Do not subject the product to excessive force, shock, dust,
temperature, or humidity, which may result in malfunctions,
shorter lifespan, damaged batteries, and damaged parts.
•Do not tamper with the unit’s internal components. Doing so
will invalidate the warranty and may cause damage. This unit
contains no user-serviceable parts.
•Use only fresh batteries. Do not mix new and old batteries.
•Read the user's manual thoroughly before operating the unit.
