ADDITIONAL EQUIPMENT

(not included)

1. 1 Philips screwdriver.

2. 4 Fresh AA 1.5V batteries.

(2 for each indoor weather station)

3. 2 Fresh AA 1.5V batteries.

(for temp/humidity sensor)

QUICK SETUP

Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.

1. Have the indoor weather stations and remote temp/humidity sensor 3 to 5 feet apart.

2. Batteries should be out of all units for 10 minutes.

3. Place the batteries into the remote temp/humidity sensor first, then into the indoor weather stations.
(All remote temp/humidity sensors must be started before the indoor weather stations)

4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.

In this time the indoor weather stations and remote temp/humidity sensor will start to talk to each other and the displays
will show both the indoor temperature and an outdoor temperature and humidity. If the indoor weather stations do not
display both the indoor temperature and the outdoor temperature and humidity after the 15 minutes please retry the set
up as shown on page five.

After both indoor temperature and outdoor temperature and humidity are displayed for 10 minutes you can place your
remote temp/humidity sensor outdoors and set your time.

Notes on Outdoor Sensor Placement

The remote temp/humidity sensor should be placed in a dry, shaded area. Fog and mist will not harm your remote
temp/humidity sensor but direct rain must be avoided.

The remote temp/humidity sensor has a range of 80 feet. Any walls that the signal will have to pass through will
reduce distance. An outdoor wall or window can have up to 30 feet of resistance and an interior wall can have up to 20
feet of resistance. Your distance plus resistance should not exceed 80 ft. in a straight line.

Notes on Weather Station Placement

The 80 ft distance is between each indoor weather station and the temp/humidity sensor independently. The placement
of one indoor weather station does not affect the placement of the second indoor weather station.
To complete the set up of your indoor weather stations after the 10 minutes have passed, please follow the steps below.

1. Press and hold the “SET” button for five seconds.

2. The hour will now be flashing.

a. Press and release the “+” button until the correct hour is shown.
Note: There is “PM” displayed to the left of the hour when between noon and midnight. During the AM
hours this area will be blank.
b. When the correct hour is shown, press and release the “SET” button once.

3. The minutes will now be flashing.

a. Press and release the “+” button until the correct minutes are displayed.

Press and release the SET button once more and you are done.

DETAILED SETUP GUIDE

I. BATTERY INSTALLATION

A. REMOTE TEMP/HUMIDITY SENSOR

Battery
compartment

Battery cover

1. Remove the mounting bracket.

2. Remove battery cover

3. Observing the correct polarity, install 2 AA batteries—make sure they do not spring free, or start-up problems

may occur.

4. Replace Cover

B. INDOOR WEATHER STATIONS

Note: After the batteries are installed, DO NOT press any buttons for 15 minutes. This may interfere with the signals,

causing temperatures to register incorrectly.

1. Remove the battery cover on the backside. To do this, push up and pull out.

2. Observing the correct polarity, install 2 AA batteries.

3. Replace battery cover.

4. Wait 15 minutes or until both the indoor and outdoor temperatures are shown on the indoor weather station.

5. The indoor weather stations should now show: “-:- -” in the TIME LCD, indoor temperature in the INDOOR

LCD and outdoor temperature and humidity in the OUTDOOR LCD.

7. The hour will begin to flash.

8. Press and release the “+” button to advance the hour to your desired hour.

9. Press and release the “SET” button to move to the minute setting.

10. The minutes will begin to flash.

11. Press and release the “+” button to set the minutes.

12. Press and release the “SET” button to activate the clock.

area will be blank.

FEATURES

A. MINIMUM AND MAXIMUM TEMPERATURES

1. Press and release the “MIN/MAX” button, “MAX” appears at the bottom of the display and the recorded

maximum temperatures are displayed.

2. Press and release the “MIN/MAX” button to toggle to the minimum temperatures, “MIN” appears at the bottom

of the display and the recorded minimum temperatures are displayed.

B. RESETTING THE MINIMUM AND MAXIMUM TEMPERATURES

To reset both the minimum and maximum temperatures—press and hold the “MIN/MAX” button for 5 seconds.

C. ADDING ADDITIONAL REMOTE TEMP/HUMIDITY SENSORS

(OPTIONAL)

The WS-7212U is able to receive signals from 3 different remote temperature, temperature/humidity sensors.
Following are some brief instructions for the basic set-up of remote sensor units with the WS-7212U. These extra
sensors can be purchased through the same dealer as this unit, or by contacting La Crosse Technology directly. A
TX6 will monitor temperature only, a TX3U will monitor temperature and display the temperature on its LCD, the
TX3UP will monitor the temperature via a probe for use in pools, spas, etc and the TX4U will monitor temperature
and humidity.

Note: When setting up multiple units it is important to remove the batteries from all existing units in operation,
then to insert batteries first into all the remote temp/humidity sensor units, and in numeric sequence. Second,
install batteries into the indoor weather stations. Transmission problems will arise if this is not done correctly and
if the total time for set-up exceeds 6 minutes.

1. It is necessary to remove the batteries from all units currently in operation.

2. Remove the battery covers to all remote sensor units.

3. Place all remote sensor units in a numeric sequential order.

4. In sequential order, install batteries (follow the same battery installation procedures seen in section “I” of the

Detailed Set-Up Guide) into the remote sensors.

5. Install batteries into the indoor weather stations.

6. Follow the Detailed Set-Up Guide for programming and operating instructions.
