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.
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. NOTE: Fog and mist will not harm your remote temperature sensor but direct rain must be avoided. To complete the set up of your indoor temperature station after the 15 minutes have passed please follow the steps in the detailed set up guide on page 8.

ADDITIONAL EQUIPMENT (not included) 1. 1 Philips screwdriver. 2. 2 Fresh AA Alkaline batteries. 3. 2 Fresh AA Alkaline batteries DETAILED SETUP GUIDE Battery Installation 1. Install 2 AA batteries in the remote temperature sensor. Make sure they do not spring free, or start-up problems may occur. 2. Install 2 AA batteries in the indoor weather station. Do not press any buttons for at least fifteen minutes.
Setting the time 1. 2. 3. 4. 5. 6. 7. Press and hold the “SET” key for 4 seconds. The hour will flash. Press and release the “+” key to advance the hour. Press and release the “SET” key. The minute is flashing. Press and release the “+” key to advance the minutes. Press and release the “SET” key to exit programming.
FEATURES Minimum and Maximum Temperatures 1. Press and release the “MIN/MAX” button, “MAX” appears between the indoor and remote temperatures. 2. The recorded maximum indoor and remote temperature is displayed. 3. Press and release the “MIN/MAX” button. 4. “MIN” appears between the indoor and remote temperatures. 5. The recorded minimum temperature is displayed. 6. Press and release the “MIN/MAX” button to exit min/max mode. 7.
Resetting Min and Max Temperatures To reset both the minimum and maximum temperatures—press and hold the “MIN/MAX” button for 5 seconds. Adding Additional Remote Temperature Sensors (optional) The WS-7211U is able to receive signals from 3 different remote temperature sensors. Following are some brief instructions for the basic set-up of remote temperature sensor units with the WS-7211U.
TX3UP will monitor the temperature of water or soil via a probe. When setting up multiple remote temperature sensors, it is important to remove the batteries from all existing units in operation, then to insert batteries first into all the remote temperature sensors. Second install batteries into the indoor weather station and do not press any buttons for ten minutes. Transmission problems will arise if this is not done correctly.
Weather Forecast The weather forecasting feature is estimated to be 75% accurate. The weather forecast is based solely upon the change of air pressure over time. The WS7211U averages past air-pressure readings to provide an accurate forecast, creating a necessity to disregard all weather forecasting for 12-24 hours after the unit has been set-up, reset, or moved from one altitude to another (i.e. from one floor of a building to another floor).
Weather Icons There are 3 possible weather icons that will be displayed in the FORECAST LCD: Sunny—indicates that the weather is expected to improve (not that the weather will be sunny). Sun with Clouds— indicates that the weather is expected to be fair (not that the weather will be sunny with clouds).
weather will be rainy). The weather icons change when the unit detects a change in air pressure. The icons change in order, from “sunny” to “partly sunny” to “cloudy” or the reverse. It will not change from “sunny” directly to “rainy”, although it is possible for the change to occur quickly. If the symbols do not change then the weather has not changed, or the change has been slow and gradual.
arrow pointing down indicates that the air pressure is decreasing and the weather is expected to become worse or remain poor. No arrow means the pressure is stable. MOUNTING Note: To achieve a true temperature reading, avoid mounting in direct sunlight. We recommend that you mount the remote temperature sensor on a Northfacing wall. The sending range is 80ft; obstacles such as walls, concrete, and large metal objects will reduce the range.
Indoor Weather Station 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 an appropriate location. To wall mount the indoor weather station first remove the table stand. Next insert an appropriate screw in your desired location. Using the integrated hanging hole on the back of the unit, slip indoor weather station over the screw and pull down to secure.
Problem: No outdoor temperature is displayed. Solution: 1. Remove all batteries, reinsert into remote temperature sensor first, then into the indoor weather station. 2. Place remote temperature sensor closer to the indoor weather station. 3. Be sure all batteries are fresh. 4. Place remote temperature sensor and indoor weather station in position so the straight-line signal is not passing through more than two or three walls. Problem: Temperatures do not match if units are placed next to each other.
environments. The indoor sensor is less responsive to ambient air currents because of the shielding effect of the display's case. In addition, the case can act as a heat sink to absorb and store heat from external sources (i.e. handling of the case or radiant heat). Also, the much greater range of the outdoor temperature sensor requires a different calibration curve than the indoor range.
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 repairs.
