Features of the Wind Sensor The wind sensor measures wind speed and wind direction and sends the data to the thermometer-transmitter sensor, which in turn transmits the data to the home monitor. Operating power is taken from the thermometer- transmitter sensor by cable connection. The wind sensor consists of the main unit with wind vane, 9m/30 ft. cable (already attached to the main unit) mast, and base bracket. Features of the Rain Sensor The rain sensor measures cumulative rainfall and sends the data to the thermometer-transmitter sensor via cable connection, which is then transmitted back to the home monitor. The cable connection also supplies operating power from the thermometer-transmitter sensor to the Rain Sensor. The rain sensor consists of the main unit and 9m/30 ft. cable (already attached to the main unit). 4. MOUNTING CAUTION: Great care must be taken when mounting the HWS components. The manufactuer/supplier cannot be held liable for personal or property damage when setting up the components. Please use caution when choosing a mounting point. Prior to drilling mounting holes and permanently affixing any of the units, please ensure the following points are considered: 1. Cable lengths of the units meet with your distance requirements at mounting points. 2. Signal from the thermometer-transmitter sensor can be received by the home monitor at mounting point. 3. Make sure the transmitter is easily accessible. You will have to periodically replace batteries. Mount it as close to the ground as possible. A. Home Monitor With three retractable legs at the back of the home monitor, the unit can be placed onto any flat surface or mounted on a wall by using a nail or screw (not provided) • For accurate data transmission, make sure that the home monitor is not placed in direct sunlight, or placed in an area with drafts caused by heaters or air conditioners. • Do not mount the home monitor on a wall which has metal heat/air conditioning ductwork or high voltage wiring in the wall behind the station, it may interfere with its ability to receive data from the transmitter. • Do not mount the home monitor close to fluorescent lights or other electrical appliances. Such devices dramatically decrease signal reception, and in some cases, prevent all signals from reaching the home monitor.
B. Wind Sensor First, choose whether the wind sensor will be mounted vertically or horizontally (on a mast). Make sure that you position the wind sensor in a free, open area that is not protected by objects, which may distort or interfere with the wind (e.g. large buildings, trees, chimney, etc.). NOTE: Make sure the following contents have been included with your HWS for mounting the wind sensor: • 2 x U-bolts to secure to a mast • 8 x washers • 4 x nuts • 8 x 0.25" screws (to fix mast to main unit and base bracket) • 4 x 2.75" screws (to fix base bracket to a flat surface) Cable Preparation for Vertical Mounting 1. Run the cable that is already fastened to the wind sensor through the vertical joining section (see right). 2. Run the cable through the extension pole but do not secure the pole to any sections yet. 3. Now run the cable through the top of the base-bracket and then through the small rectangular section found on one side of the base- bracket. NOTE: Make sure that you completely pull the cable through the wind sensors extension pole and base-bracket to reduce the amount of slack on the cord. VERTICAL MOUNT Vertical Mount 1. Make sure that the wind vane can rotate freely before fastening the unit permanently into position.
NOTE: For proper wind speed measurement ensure the vertical joining section is at 90º the horizon (Fig.A). Horizontal Mounting Cable Preparation for Horizontal Mounting 1. Run the cable that is already fastened to the wind sensor through the horizontal joining section (see below). 2. Run the cable through the extension pole but do not secure the pole to any sections yet. 3. Now run the cable through the top of the base-bracket and then through the small rectangular section found on one side of the base-bracket. NOTE: Make sure that you completely pull the cable through the wind sensor's extension pole and base-bracket to reduce the amount of slack on the cord. Horizontal mount - using a mast/antenna/pole NOTE: It is not recommended to secure the wind sensor horizontally from a wall or chimney because doing so will interrupt the flow of wind from at least one direction. MOUNT WITH "N"...
HORIZONTAL MOUNT C. Rain Sensor NOTE: Make sure the following contents have been included with your HWS for mounting the rain sensor. • 2 x 2.75" screws (to fix rain sensor to a flat surface) Place the rain sensor as far away as possible from tall buildings, trees or other obstructions. It is suggested that the rain sensor should be no closer to tall objects or obstructions than twice the height of the object compared to the sensor. However, low bushes, fences or walls in the vicinity of the gauge are not objectionable, as these usually help break up the force of the wind during stormy weather conditions. NOTE: It is recommended that you mount the rain sensor 18" (46 cm) above ground or surface to prevent water from splashing off the ground/surface, into your rain gauge. 1. In order for the rain sensor to work properly, you MUST place the rain sensor on a level, horizontal surface. Use of a bubble level (not included) will ensure proper mounting. 2. Remove the rain gauge lid by pushing on the tabs at either end, and pulling it upwards off the base.
D. Thermometer-Transmitter Sensor It is recommended to mount the thermometer-transmitter sensor in a shaded area out of reach of direct sunlight. Placing the transmitter in direct sunlight will affect the outdoor temperature considerably. It is recommended to mount the unit approximately 2 m /6 ft above the ground on the north side of a structure preferably in a shaded area. NOTE: Make sure the following contents have been included with your HWS for mounting the transmitter: • 2 x 1.75" wall mounting screws • plastic anchors for screws Wall Mount 1. Affix the wall bracket onto a desired wall using the 1.75" screws provided 2. Insert the plastic plug on the back of the thermometer-transmitter sensor into the wall bracket socket. Vertical Mount 1. Affix the wall bracket onto a flat, horizontal surface using the 1.75" screws provided. 2. Plug in the thermometer-transmitter using the plug found on the bottom of the sensor into the wall bracket socket. DO NOT mount the thermometer-transmitter sensor upside down. WALL MOUNT VERTICAL MOUNT 5. CONNECTING THE SENSOR Thermometer-Transmitter Sensor You must insert the cables that run from the outdoor sensors into the corresponding sockets on the thermometer-transmitter before you can begin to power up your home weather station. 1. You will see three sockets: one for the wind sensor, one for the wired transmission, another for the rain sensor (see Diagram C). 2. Connect the cables of the wind and rain sensors to the corresponding sockets on the thermometer-transmitter by 'clicking' them into place.
6. POWERING UP YOUR HWS NOTE: The AC/DC adaptor should be used as the primary power source for the home monitor and batteries should only be used for back up purposes in case of a power outage. 1. Plug in the AC/DC adaptor to the power outlet in your wall. 2. Insert the adaptor into the DC socket located on the right side of the home monitor. 3. Once the adaptor has been plugged in, "IO" will flash on the top left side of the LCD and "---" will appear in the center of the compass rose. (See diagram A). 4. Remove the battery cover on the thermometer-transmitter sensor. 5. Insert 4 x "AA" batteries according to the correct polarity. 6. If the home monitor is receiving transmissions properly from the thermometer-transmitter sensor, a transmission ID number will appear in the center of the compass rose on the home monitor (e.g. 104, 241, etc.) (See diagram B). Diagram A Diagram B NOTE: If no transmission ID number appears after 4 minutes, remove the batteries from the transmitter and uplug the AC/DC adaptor from the home monitor and start from step one. 7. Once the transmission ID number and the "IO" stop flashing on the LCD, press the SET button on the monitor to store the transmission ID. The monitor will automatically go to the normal display mode. 8. Replace the battery cover and the rain cover on the thermometer-transmitter sensor. 9. After the set up is complete you can now insert 3 x "AA" batteries into the home monitor for back up purposes only. IMPORTANT: It is very important that the steps in "Powering Up Your HWS" are followed precisely. Missing a step or not performing the steps in order will result in the home weather station to not function properly and therefore will result in incorrect readings. 7. CHANGING BATTERIES IN THE TRANSMITTER 1. Press and hold the DISPLAY button until the LCD exits the normal display mode and "IO" begins to flash in the top left corner.
9. OPTIMUM VIEWING ANGLE You must always keep in mind that the LCD screen is constructed with an "optimum viewing angle". Your eye should be at a 45º angle to view the LCD screen clearly. 45º 10.

TURNING OFF THE ALARM(S) • If any of the alarms sound, press and release the ALARM button to deactivate the signal ("beeping"). “((•))” flashes to indicate which alarm has sounded. This will only turn off the alarm that has sounded at that particular point in time. Example: If the alarm clock sounds and the temperature alarms are set, you can press the ALARM button to turn off the alarm clock, however, the temperature alarms will remain active. • Once you have deactivated a sounding alarm by pressing the ALARM button, you must reset the alarm by following all the steps in the "Setting the Alarm" section. 14. SIGNAL STRENGTH This icon indicates the strength of the transmission between the transmitter and the home monitor. The signal strength is represented by three levels: 15 . INTERFERENCE LEVEL This interference icon determines the amount of transmission interference that is around the home monitor. If the home monitor is in an area with high transmission interference the icon on the monitor will constantly be displayed. The interference signal is represented by three levels:...
16. INDOOR/OUTDOOR BATTERY LEVEL The battery level shows the actual voltage of the battery in the transmitter and the home monitor. The battery level is represented by three levels: When there are no batteries in the home monitor or transmitter the battery icon will flash. 17. MINIMUM OR MAXIMUM MEMORY RECALL Press the MIN button to recall all the minimum recorded weather measurements. (Including Wind Chill, Wind Speed, Indoor Temperature, Outdoor Temperature, Pressure and Humidity). Press the MAX button to recall all the maximum recorded weather measurements. (Including Wind Chill, Wind Speed, Indoor Temperature, Outdoor Temperature, Pressure, Humidity and Rainfall). 18. MINIMUM OR MAXIMUM MEMORY RESET Press and hold the MIN button for 4 or more seconds to reset all the minimum recorded weather measurements. Press and hold the MAX button for 4 or more seconds to reset all the maximum recorded weather measurements. 19. RAINFALL MEASUREMENT RESET The Home Weather Station calculates cumulative rainfall. To reset the rainfall reading, press and hold the "+" button for 4 or more seconds. "---" (dashes) will appear to indicate that the rainfall has reset. After 128 seconds, the reading will return to 0.0 cm (or 0.0 inch). 20. TREND CHART Please review the following tips on understanding your trend chart. NOTE: • The trend chart will not appear on the LCD after powering up the home monitor for the first time. It has to collect air pressure data for 24 hours before it can display a trend. • If at anytime power is lost to the home monitor, all trend information will be erased and must be collected again for 24 hours to display a trench once the power is restored.
21. WEATHER FORECASTING • Weather forecasting is an extremely complex science. Even professional meteorologists with the best equipment and the aid of radar and satellite imagery often have difficulty forecasting with absolute certainty. The predication models meteorologists use consider many weather variables, including; barometric pressure, wind direction, wind speed, dew point, etc. • The forecast function in the Home Weather Station is based solely on barometric pressure and the trend recordings of general weather conditions associated with various pressure levels. It therefore has a limited ability to forecast for the multitude of specific conditions it will encounter. It provides a general forecast of weather changes in the same way a wall barometer forecasts changes in weather, however it does record and account for trends that influence the forecast icon. IMPORTANT: • The forecast icon will always appear as "Partly Cloudy" upon powering up the home monitor. During this time, the main station is collecting pressure information in order to generate a proper forecast. • The first 72 hours of forecast icons may be inaccurate from what you are viewing out your window, however, the unit continually gathers pressure data to develop trends, in turn predicting forecasts of coming weather conditions. The longer that station is powered increases the forecast accuracy. 22. WIND CHILL • Wind chill is a combination of both outdoor temperature and wind speed. • For the wind chill to display on the home monitor the outdoor temperature needs to be above -50 º C (-58 º F) and below 10 º C (50 º F) and the wind speed needs to be above 4.8 km/hr (3 mph) and below 177 km/hr (110 mph). If the outdoor temperature and wind speed are out of the range the wind shill will display dashes ("---"). 23. BAROMETRIC PRESSURE • The Home Weather Station's barometer display will differ from local sources (TV, radio, internet, etc.). This is because the barometric pressure quoted in these types of mediums is "barometric pressure adjusted to sea level", which is theoretical atmospheric pressure that accounts for decreasing air pressure with elevation. Air pressure decreases 1.0 inHg for every 30 meters / 1000 feet you go up in elevation. Consequently, the air pressure at the top of a mountain is considerably less than at sea level.

24. TROUBLESHOOTING LCD is blank A. This occurs because there is no power supplied to the main unit. 1. Check the AC power connections to the receiving unit and the power from the wall outlet. 2. Check the batteries and replace if needed (View Section 7: Changing Batteries in the Transmitter). 3. Check the polarity of the batteries in the battery compartment. 4. Press the DISPLAY button to see if you are in a particular display mode screen. Outdoor information is not A. This is usually caused by transmission interference or low battery power in displayed, "---" the transmitter.

Make sure that the wind speed sensor cord is securely fastened in the "wind" slot on the transmitter. (View Section 5: Connecting the Sensors). 4. Bring the monitor beside the transmitter and remove all the batteries. Replace them all (View Section 6: Powering Up Your HWS) and observe whether ALL the outdoor readings show up. Check the timing of updates on the receiving unit (outdoor readings should change every 128 seconds). Then, place the monitor back in the regular position. Check the timing of updates AGAIN on the receiving unit. If you notice the updates occur every 128 seconds, there should be no problem. If the screen has not updated within 5 minutes or no updates occur there is transmission interference between the receiver and the transmitter. BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE TRANSMISSION INTERFERENCE. 5. Freezing rain can cause the wind direction pointer to stop moving, thus constantly displaying the same direction. You can attempt to remove the ice from the wind sensor, but it is strongly advised to wait for milder weather to do so. Outdoor readings stopped after 1. Battery voltage supplied by the 4 x "AA" batteries in the transmitter two days, one week, etc. is affected by cold weather, especially alkaline batteries. Low voltage decreases the transmission distance significantly. If you are experiencing weather below -10 º C/14 º F, it is suggested to use lithium batteries and place the monitor and transmitter as close as possible to each other. • Power Adaptor: a special transmitter adaptor is available to supply power to the transmitter rather than using batteries. It is a perfect solution for your HWS during extremely cold temperatures in the winter months when batteries may cause problems. Please call 1-800-387-8520 for ordering information if not found at a local retailer. 2. Electrical storms can cause transmission to stop. If this occurs, you must reset the monitor and transmitter by removing the batteries and re- inserting them correctly (View Section 6: Powering Up Your HWS). DO NOT do this during the electrical storm! 3. Electromagnetic interference can occur from different sources that...

Wind direction is displaying i) Are you mounting the unit on a mast or metal pole? ii) Do you know what the pole is made of? faculty readings Wind direction is stuck on one 1. Aluminum poles should not affect the wind direction readings, however, direction masts or poles made of lead or other dense metals can affect the magnetic sensors in the wind sensor causing the unusual readings. Move the wind sensor, if necessary, or use the vertical mount procedure. (View Section 4: Mounting). 2. Freezing rain can cause the wind direction pointer to stop moving, thus constantly displaying the same direction. You can attempt to remove the ice from the wind sensor, but it is strongly advised to wait for milder weather to do so. 3. Check the batteries in the transmitter. Replace if needed.

Pressure reading is too high / The pressure sensor in your weather station is very sensitive to voltage low / changed changes if you scroll through the display screen (using the DISPLAY button) or plug in the AC adaptor with the batteries in it, the pressure may change because the voltage to the sensor has either increases or decreased. After a very short period of time, the pressure sensor will adjust itself back to the correct pressure readings. Only transmits when the A. There is a large amount of transmission interference with the current transmitter is right beside the location of the main unit and transmitter. There may be too many walls receiver or electrical interference (caused by appliances in your home) between the two units. 1. Significantly reduce the distance between the main unit and the transmitter. 2. Bring the monitor beside the transmitter and remove all the batteries. Replace them all (View Section 6: Powering Up Your HWS). Connect the sensors and observe whether ALL the outdoor readings show up. Check the timing of updates on the home monitor (outdoor readings should change every 128 seconds). Then, place the monitor back in the regular position. Check the timing of updates AGAIN on the receiving unit. If you notice the updates occur every 128 seconds, there should be no problem. If the screen has not updated within 5 minutes or no updates occur there is transmission interference between the receiver and the transmitter. BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE TRANSMISSION INTERFERENCE. No outdoor reading occur even A. Make sure that you have unplugged and removed the batteries from the after resetting the units main unit AND the transmitter. Re-insert the batteries in the transmitter ONLY. Put the transmitter directly on top of a radio (preferably a clock- radio due to the size - stereo radios may be too large for this test), and turn the radio to FM 107.9. You should hear a loud beep or pulse roughly every 128 seconds. Time the pulse to ensure this occurs approximately every 128 seconds. If no pulse is heard, the transmitter's batteries are dead or the trasnmisster is defective. If the pulse does occur approximately every 128 seconds, place the main unit and the transmitter side by side (turn off the radio). Bring the monitor beside the transmitter and remove all the batteries. Replace them all (View Section 6: Powering up your HWS) and observe whether ALL the...

BOTH UNITS MUST BE PLACED IN DIFFERENT LOCATIONS TO REDUCE TRANSMISSION INTERFERNCE. ** NOTE: the radio test is only confirming that the transmitter is sending out a signal. ** Wind speed too high Transmission issues usually cause this to occur from other appliances or (190 km to 200 km) radio waves in the air. If the problem persists, you should consider replacing the batteries in the transmitter (View Section 6: Powering Up Your HWS) and possibly moving the location of the transmitter and monitor. Wind speed to low 1. This situation can occur because the wind speed transmission is NOT REAL TIME. The wind speed is an average reading of gusts collected Wind speed not accurate before transmission, therefore if wind gusts happen (every 128 seconds) to dip below the perceived wind speed over the measuring period, the average will be reduced, resulting in what appears to be a low reading. 2. Is the anemometer clear of obstructions? Wind speed & direction can be affected radically by obstructions that interfere with actual wind. This affect can take place many meters away from the sensor. Example: a 40' tree even 50 meters from the sensor on the roof of a house will disturb enough wind that the unit will never give proper data from the direction of that tree. 3. Wind speed and directional data will not change if there is "transmission interference". That means that some of the data transmitted has been corrupted by other sources emitting waves. This could be anything - wiring in walls, appliances, other electrical devices operating in proximity of the monitor or transmitter, or between the two. 4. Freezing rain can cause the wind speed cups to stop moving, thus constantly displaying 0.0 wind speed. You can attempt to remove the ice from the wind sensor, but it is strongly advised to wait for milder weather to do so. Barometric trend doesn't work Bring the monitor beside the transmitter and remove all the batteries. Replace them all (View Section 6: Powering Up Your HWS). Connect the sensors and observe whether ALL the outdoor readings show up. Check the timing of updates on the home monitor (outdoor readings should change every 128 seconds). Then, place the monitor back in the regular position. Check the timing of updates AGAIN on the receiving unit.

The trend function will not display after power up until it has collected 24 hours of pressure data. (View Section 20: Trend Chart). The forecast icon will always appear as "Partly Cloudy" upon powering Forecast icons don't change up the home monitor. The first several hours of forecast data may be inaccurate, because the home monitor needs to collect barometric pressure information. Over time the forecast icon's accuracy will improve. (View Section 21: Weather Forecasting). The "most accurate" professional weather forecasting system is only 70.2% Forecasts icons limitations accurate. Forecasting is a very complex science involving very powerful computer models, satellite imagery and radar. Scientific forecasts consider barometric pressure, wind direction, dew point, etc. The HWS forecasts only evaluates the barometric pressure change over a certain period of time. It is very much like using a traditional dial barometer for predicating changes in the weather. The Home Weather Station requires constant battery power to accurately Battery consumption scan outdoor weather readings. The wind speed sensor and the 60 m (60 yards) transmission is the main cause of power consumption. In normal temperature ranges (10 º C to 25 º C / 50 º F to 80 º F), you can expect that the 4 x "AA" batteries in the transmitter will last approximately 7 weeks (even lithium batteries). In colder temperatures, battery life is much less - not that the use of lithium batteries allow the chemical reaction that is creating power to occur in colder temperatures -40 º C (-40 º F) compared to alkaline batteries, which fail at approximately -10 º C (14 º F), but it does not necessarily mean that the battery's charge will last longer.
