ADDITIONAL EQUIPMENT
(not included)
1. 1 Philips screwdriver.
2. 2 Fresh AAA 1.5V batteries.
3. 2 Fresh AA 1.5V batteries
QUICK SETUP
Hint: Use good quality Alkaline Batteries
and avoid rechargeable batteries.
1. Have the indoor temperature station and
remote temperature sensor 3 to 5 feet
apart.
2. Batteries should be out of both units for
10 minutes.

3. Place the batteries into the remote
temperature sensor first then into the
indoor temperature station.
(All remote temperature sensors must be
started before the indoor temperature station)
4. DO NOT PRESS ANY BUTTONS FOR
15 MINUTES.
In this time the indoor temperature station and
remote temperature sensor will start to talk to
each other and the display will show both the
indoor temperature and an outdoor
temperature. If the indoor temperature station
does not display both temperatures after the
15 minutes please retry the set up as stated
above. After both indoor and outdoor
temperatures are displayed for 15 minutes
you can place your remote temperature
sensor outdoors and set your time.
The remote temperature sensor should be
placed in a dry, shaded area. The thermo-
hygro sensor has a range of 330 feet. Keep
in mind that the 330 feet is in open air with no
obstructions and that radio waves DO NOT
curve around objects. Actual transmission
range will vary depending on what is in the
path of the signal. Each obstruction (roof,

6
walls, floors, ceilings, thick trees, etc.) will
effectively cut signal range in half.
Example: A wireless weather station with a
330 feet range is mounted on an interior wall,
so that the signal has to pass through one
interior wall, one exterior wall, and across the
10 feet width of the room between the 2 walls.
The first wall will reduce the range to 165 feet,
and the second wall will reduce the range to
87 feet. Factoring in the 10 foot room, this
leaves a maximum of 77 feet of remaining
signal range.
This allowance is typically enough for a frame
wall with non-metallic siding; however certain
materials can reduce range even further.
Metal siding, stucco, and some types of glass
can reduce signal range by as much as ¾ or
more, compared to the ½ reduction typical of
most obstructions. It is possible to receive a
signal through these materials, however
maximum range will be much less due to their
tendency to absorb or reflect a much larger
portion of the sensor’s signal.

To complete the set up of your indoor
temperature station after the 15 minutes have
passed please follow the steps below.
1. Press and hold the “SET/CH” button for
5 seconds.
Note: A “12h” or “24h” will appear on the
top line. (“12h” for AM/PM, “24h” for
military time)
2. To change between “12h” and “24h”
press and release the “MIN/MAX” button.
3. When you have your choice shown on
the display press and release the
“SET/CH” button once.
Note: if “12h” is selected, the temperature is
displayed in degree Fahrenheit. If “24h” is
selected, the temperature is displayed in
degree Celsius
4. An hour will now be flashing.
5. Press and release the “MIN/MAX” button
until the correct hour is shown.
Note: When in the 12h mode there is
“PM” displayed under the word TIME
when in the PM hours. During the AM
hours this area will be blank.

6. When the correct hour is shown, press
and release the “SET/CH” button once.
Press and release the SET button once
more and you are done.
DETAILED SETUP GUIDE
BATTERY INSTALLATION - When one
Temperature sensor is being used
1. First, insert the batteries to the
Temperature sensor (see “A.
Temperature sensor” below).
2. Within 2 minutes of powering up the
sensor, insert the batteries to the
Temperature Station (see “B. Indoor
Temperature station” below). Once the
batteries are in place, all segments of
the LCD will light up briefly. Following
the indoor temperature and the time as
12:00 will be displayed. If they are not
shown in LCD after 60 seconds, remove
the batteries and wait for at least 60
seconds before reinserting them. Once
the indoor data is displayed user may
proceed to the next step.
3. After the batteries are inserted, the
Temperature Station will start receiving
data signal from the sensor. The outdoor

9
temperature and humidity should then be
displayed on the Temperature Station. If
this does not happen after 2 minutes, the
batteries will need to be removed from
both units and reset from step 1 and the
signal reception icon is no longer shown.
A. REMOTE TEMPERATURE SENSOR
a. Remove the
mounting
bracket.
b. Remove battery
cover
c. Observing the
correct polarity,
install 2 AA
batteries—make
sure they do not spring free, or
start-up problems may occur.
d. Replace cover.
B. INDOOR TEMPERATURE STATION
Note: After the batteries are installed, DO
NOT press any buttons. This may interfere
with the signals, causing temperatures to
register incorrectly.
