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 theindoor 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.

C. ADDING ADDITIONAL REMOTE TEMP/HUMIDITY SENSORS (OPTIONAL)

The WS-7212Uis able to receive signals from 3 different remote temperature, temperature/humidity sensors. Following are some brief instructions for the basicset-upof remote sensor units with theWS-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 forset-upexceeds 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-UpGuide) into the remote sensors.

5.Install batteries into the indoor weather stations.

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

D.VIEWING AND OPERATING WITH MULTIPLE REMOTE SENSOR UNITS

1.To view the temperature of a different remote sensor unit, press and release the “CH” button. A shift from one “boxed” number to the next should be observed in the OUTDOOR LCD.

2.To view the Minimum/Maximum temperature: first select from which remote temp/humidity sensor to read data from (indicated by the “boxed” number). Pressing and releasing the “MIN/MAX” button will toggle through the minimum and maximum indoor temperature, and the minimum and maximum outdoor temperature.

3.To reset the Minimum/Maximum readings, press and hold the “MIN/MAX” button for five seconds.

MOUNTING

Note: To achieve a true temperature reading, avoid mounting in direct sunlight. We recommend that you mount the remote temp/humidity sensor on an outsideNorth-facingwall. The sending range is 80ft; obstacles such as walls, concrete, and large metal objects will reduce the range. Place both units in their desired location temporarily to test reception capability before permanently mounting.

A.REMOTE TEMP/HUMIDITY SENSOR

1.Remove the mounting bracket from the remote temp/humidity sensor

2.Mount using either screws or adhesive tape.

3.Reattach the remote temp/humidity sensor to the mounting bracket.

B.THE WEATHER STATION

1.The indoor weather station comes with the table stand already mounted. If you wish to use the table-stand,all that is required is to place the indoor weather station in your desired location.

2.To wall mount:

a)Remove the table stand by pulling down on the stand from the rear and rotating forward.

b)Fix a screw (not included) into the desired wall.

c)Place the indoor weather station onto the screw using the hanging hole on the backside.

d)Gently pull the indoor weather station down to lock the indoor weather station into place.

TROUBLESHOOTING

NOTE: For problems not solved, please contact La Crosse Technology viae-mailor phone, or visit our website, www.lacrossetechnology.com

Problem: The LCD is faint

Solution: Replace batteries

Problem: No outdoor temperature or humidity is displayed.

Solution:

1)First try to re-establishcommunication between the remote sensor and indoor weather station by moving both units to within three to five feet of each other. Wait about ten minutes and then check for a temperature and humidity.

2)If this does not work please remove the batteries from both units and restart the system (please see Detailed Set-upon page nine through eleven).

Note: Please make sure when restarting the system that all batteries are fresh.

3)Once the system has been reset and you have a temperature and humidity reading from the sensor, temporarily place the remote temp/humidity sensor in the previous location.

Note: If there is a outdoor temperature and humidity displayed when the two units are close together there was either too much distance between the two units previously or some type of interference that was causing poor reception.

4)If after 15 minutes the temperature and humidity are not displayed you will need to choose another location for placement of the temp/humidity sensor.

5)The best way of doing this is to move the sensor 10 feet closer to the indoor weather station.

6)After moving the remote temp/humidity sensor please wait 15 minutes to give the indoor weather station time to

re-acquirethe signal.

7)

Problem: Temperatures do not match if units are placed next to each other.

Solution: Each temp/humidity sensor is manufactured to be accurate to within 2 degree plus or minus and under normal conditions. It is possible for two temp/humidity sensors to be as much as 4 degrees different. The difference can be exaggerated further because the temp/humidity sensors are designed for different working environments. The indoor sensor is less responsive to ambient air currents because of the shielding effect of the indoor weather station’s case. In addition, the casing can act as a heat sink to absorb and store heat from external sources (i.e. handling of the case or radiant heat). In addition, the much greater range of the outdoor temp/humidity sensor requires a different calibration curve than the indoor range. Error is usually greater at the extreme ends of a range, making it harder to compare different ranges with different curves. Undernon-laboratoryconditions, it is difficult to compensate for the above factors and obtain an accurate comparison.

MAINTENANCE AND CARE INSTRUCTIONS

Extreme temperatures, vibration, and shock should be avoided to prevent damage to the units.

Clean displays and units with a soft, damp cloth. Do not use solvents or scouring agents; they may mark the displays and casings.

Do not submerge in water.

Do not subject the units to unnecessary heat or cold by placing them in the oven or freezer.

Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La Crosse Technology for repairs.
