Avoid direct rain and sunshine QUICK SET-UP GUIDE Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries. 1. Have the intelligent weather station and remote temperature/humidity sensor 3 to 5 feet apart. 2. Batteries should be out of both the intelligent weather station and remote temperature/humidity sensor units for 10 minutes. 3. Place the batteries into the remote temperature/humidity sensor first then into the intelligent weather station. 4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES. In this time the intelligent weather station and remote temperature/humidity sensor will start to talk to each other and the display will show the temperature/humidity, outdoor temperature/humidity. If the intelligent weather station does not display all information after the 5 minutes please retry the set up as stated above. After all information has been displayed for 5 minutes you can place your sensors outdoors and set your time. Important Notes on Set-up and Operation • The remote temperature/humidity sensor should be placed in a dry, shaded area. • Fog and mist will not harm your remote temperature/humidity sensor but direct rain must be avoided. • The remote temperature/humidity sensor has a range of 330 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 330 ft. in a straight line. • The remote temperature/humidity sensor transmits a signal every 4 seconds. After the batteries have been installed, the intelligent weather station will search for the signal for a duration of 45 seconds. If there is no temperature or humidity reading in the OUTDOOR LCD after 5 minutes, make sure the units are within range of each other, or repeat the battery installation procedure. • If a button is pressed before the intelligent weather station receives the signal from the remote temperature/humidity sensor, you will need to follow the battery installation procedure again. To complete the set up of your new wireless intelligent weather station after the 5 minutes have passed please follow the steps that follow in the “Manual settings”. Note: If the signal reception is not successful on the first frequency of 915MHz for 45 seconds, the frequency is changed to 920MHz and the learning is tried for another 45 seconds. If it is still not successful the reception is tried for 45 seconds on 910MHz. This will also be done during resynchronization. HOW TO INSTALL AND REPLACE BATTERIES IN THE INTELLIGENT WEATHER STATION The intelligent weather station uses 3 AA (alkaline recommended) batteries. When the batteries need to be replaced the low battery symbol will appear on the LCD. To install and replace the batteries, please follow the steps below: 1. Remove the cover. 2. Insert batteries observing the correct polarity (see battery compartment marking). 3. Replace battery cover. HOW TO INSTALL AND REPLACE BATTERIES IN THE REMOTE TEMPERATURE/HUMIDITY SENSOR The remote temperature/humidity sensor uses 2 x AA IEC LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below: 1. Remove the battery cover at the front side with a small screwdriver. 2. 3. Insert the batteries, observing the correct polarity (see battery compartment marking). Replace the battery cover on the unit. Note: When changing the batteries in any of the units, all units need to be reset by following the setting up procedures. This is because a random security code is assigned by the transmitter at start-up and this code must be received and stored by the intelligent weather station in the first few minutes of power being supplied to it. BATTERY CHANGE: It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of these units. Please participate in the preservation of the environment. Return used batteries to an authorized facility. ABOUT WWVB (Radio Controlled Time) The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time and date signal continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the Intelligent weather station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The intelligent weather station will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST Atomic clock in Boulder, Colorado. A team of atomic physicists is continually measuring every second, of every day, to an accuracy of ten billionths of a second per day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum. For more information on the atomic clock and WWVB please see the NIST website at http://www.boulder.nist.gov/timefreq/stations/wwvb.htm.

When the alarming outdoor temperature is reached, the alarm will sound. The weather alarm indicator , high or low alarm icon and the 20 temperature reading will be flashing on LCD. The alarm will sound for 120 seconds if no one stops the alarm. User may press any key to stop the buzzer ringing. Then the weather alarm indicator, alarm icon and the temperature reading will be still flashing but the sound is stopped. If the alarm key is not pressed, the weather alarm indicator will keep flashing, indicating that alarming tem,perature has been reached before. User may presses the Alarm key once to switch off the weather alarm indicator. WEATHER ALARM OPERATIONS WEATHER ALARMS The Weather alarms are settable for when certain weather conditions are met according to the users requirements. For example, the user can set the thresholds for the outdoor temperature to +104°F (+40ºC) (high) and +14ºF (-10°C) (low), whilst only enabling the high alarm and disabling the low alarm (i.e. temperatures < +14ºF (-10°C) won’t trigger alarm, but temperatures > +104ºF (+40°C) will). Alarm setting Outdoor Temperature Minimum -40°F (40ºC) Maximum +139.8°F (59.9ºC) HYSTERESIS To compensate for fluctuation of the measured data, which may cause the weather alarm to sound constantly if the measured reading is close to user set level, a hysteresis function has been implemented for each weather alarm. For example, if the high temperature alarm is set to +77°F (+25°C) and the current value moves to +77°F (+25°C), the alarm will be activated (if it has been enabled). Now when the temperature drops to +76.8°F (+24.9°C) or below and thereafter again increases to beyond +78°F (+25°C), the data will be blinking, but no alarm will be activated. It has to drop to below +75.2°F (+24°C) (with a pre-set hysteresis of 2ºF (1°C)) so that the alarm can be produced again. Hysteresis values for the various weather data types are given in the following table: 21 Weather data Temperature Humidity Air pressure Hysteresis 2°F 3% RH 0.03 inHg WEATHER FORECAST AND WEATHER TENDENCY: WEATHER FORECASTING ICONS: There are 4 weather icons in the fourth section of LCD which can be displayed in any of the following combinations: Sunny Cloudy with sunny intervals Cloudy Rainy For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the change in weather. If the icons do not change, then it means either the air pressure has not changed or the change has been too slow for the intelligent weather station to register. However, if the icon displayed is a sun or rainy, there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes. The icons displayed forecasts the weather in terms of getting better or worse and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rainy. The change of weather forecast icon is in accord to the relationship between current relative pressure and the pressure change since last three hours. 22 If the weather is changing, both old weather icon and new weather icon will be shown with weather tendency indicator (animated arrows). If the weather has not changed within 6 hours, only the new weather icon in the middle display will be shown. Examples of changing weather icons: Note: After initial set up of the intelligent weather station with the setting of the relative value, readings for weather forecasts should be disregarded for the next 12-24 hours. This will allow sufficient time for the intelligent weather station to collect air pressure data at a constant altitude and therefore result in a more accurate forecast. If the intelligent weather station is moved to another location significantly higher or lower than its initial standing point (for example from the ground floor to the upper floors of a house), set again the relative air pressure value, and discard the weather forecast for the next 12-24 hours. By doing this, the intelligent weather station will not mistake the new location as being a possible change in air-pressure when really it is due to the slight change of altitude. AIR PRESSURE TENDENCY INDICATOR The air pressure tendency indicators are located on the left side of the air pressure display, below the weather icons, and they work independently from the weather forecast icons. The air pressure tendency indicator pointing upward or downward directions is displayed 23 based on comparing the difference of the air pressure recorded during a full hour time frame. Note: • An upward air pressure tendency indicator means that there is an increase in air pressure within the past 4 hours. • A downard air pressure tendency indicator means that there is an decrease in air pressure within the past 4 hours. AIR PRESSURE The fifth section of the sections of the LCD show the relative air pressure and the air pressure history. Air pressure changes in hPa Air pressure over the last 12 hours The reference relative air pressure can be set between 28.35 to 30.72 inHg (960 to 1040hPa). See “Relative pressure value setting” in manual setting. BAR GRAPH DISPLAY Depending on programming conditions, display of the history of air pressure in form of a graph consisting of vertical bars. AIR PRESSURE HISTORY The bar graph of the electronic barometer shows the air pressure history of the past 12 hours in 7 steps. 4.5hPa 3hPa 1.5hPa 0hPa -1.5hPa -3hPa -4.5hPa -12 h -9h -6h -3h -2h 24 -1h 0h The horizontal axis represents the last 12 hours air pressure recording (-12, -6, -5, -4, -3, -2, -1, and 0 hour, from right to left). The bars are plotted at each of the 7 steps and give the trend over the recorded period. The scale on the right compares the result. The ″0″ in the middle of this scale determines the current air pressure. The vertical axis represents the air pressure changes in hPa (4.5, 3, 1.5, “0” represents the current air pressure). Each change (±1.5, ±3, ±4.5; the other values are not shown on the vertical axis but can be determined) shows in inches of mercury (hPa), how high or low the past air pressure was as compared to the current one. If the bars are rising it indicates that the weather is getting better due to an increase in air pressure. If the bars go down it indicates a drop of the air pressure and the weather is expected to get worse from the present time ″0″. At every full hour the current air pressure is used as a basis for the display of a new graph bar. The existing graph is then moved one bar to the left. Note: For accurate barometric pressure trend, the intelligent weather station should operate at the same altitude. For example, it should not be move from the ground to the second floor of the house. Should the unit be moved to a new location, discard readings for the next 12 – 36 hours. LOW BATTERY INDICATOR The low battery indicator will be displayed in the LCD when the battery power of the intelligent weather station is low. It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of the intelligent weather station. Note: After battery change, both the intelligent weather station and the transmitter(s) need to be reset (see note ”Setting up”) WEATHER INFORMATIONDISPLAY The weather information display located at the last section of the LCD will display the weather forecast based on data received from channel 1 and the air pressure.

REMOTE TEMPERATURE/HUMIDITY SENSOR / 915MHZ RECEPTION CHECK The outdoor temperature and humidity is measured and transmitted about every 4 seconds. The transmission range of the remote temperature/humidity sensor may be affected by the ambient temperature. At cold temperatures the transmitting distance may be decreased. Please bear this in mind when placing the transmitter. To install the remote temperature/humidity sensor outside, choose a shady and dry place. Before fixing the remote temperature/humidity sensor with the enclosed screws, wait for 30 minutes to see if the indoor display is able to scan the signal from this location. Obstacles (walls, windows, trees) and interfering radio waves (PC, mobile phone, TV) can impede the reception or limit the range (about 330 feet (100 meters) in open space) considerably. Should interference occur, choose another location for the remote temperature/humidity sensor and/or the intelligent weather station. If the outdoor temperature and humidity data are not being received within 2 minute after setting up (or the outdoor display show “--.-“ in the outdoor section of the intelligent weather station after failed attempts during normal operation). Please check the following points: 1. The distance of the intelligent weather station or remote temperature/humidity sensor should be at least 3 to 6 feet (1.5 to 2 meters) away from any interfering sources such as computer monitors or TV sets. 2. Avoid positioning the intelligent weather station onto or in the immediate proximity of metal doors or window frames. 28 3. 3. 4. Using other electrical products such as headphones or speakers operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception. Neighbors using electrical devices operating on the 915MHz signal frequency can also cause interference. “Visibility” of the intelligent weather station and remote temperature/humidity sensor (e.g. through a window) increases the range. Note: When the 915MHz signal is received, do not re-open the battery cover of either the remote temperature/humidity sensor or the intelligent weather station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up). POSITIONING THE INTELLIGENT WEATHER STATION: The intelligent weather station has been designed to be hang on a wall or free standing. For Free standing: Simply attached the stand to the bottom of the unit and place onto a flat surface. 29 To wall mount Choose a sheltered place. Avoid direct rain and sunshine. Before wall mounting, please check that the outdoor temperature and humidity values can be received from the desired locations. To wall mount: 1. Fix a screw (not supplied) into the desired wall, leaving the head extended out the by about 0.2” (5mm). 2. Fold the stand of the intelligent weather station by pushing inward and hang it onto the screw. Remember to ensure that it locks into place before releasing. POSITIONING THE REMOTE TEMPERATURE / HUMIDITY SENSOR: The remote temperature/humidity sensor can be placed onto any flat surface or wall mounted using the bracket which doubles as a stand or wall mount base. Table stand/wall mount bracket To wall mount: 1. Secure the bracket onto a desired wall using the screws and plastic anchors. 30 2. Clip the remote temperature/humidity sensor onto the bracket. Note: Before permanently fixing the remote temperature/humidity sensor wall base, pace all units in the desired locations to check that the outdoor temperature and humidity readings are receivable. In event that the signal is not received, relocate the remote temperature/humidity sensor or move them slightly as this may help the signal reception. CARE AND MAINTENANCE: • Extreme temperatures, vibration and shock should be avoided as these may cause damage to the units and give inaccurate forecasts and readings. • When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or scouring agents as they may mark the LCD and casings. • Do not submerge the units in water. • Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the recommended type. • Do make any repair attempts to the units. Return it to their original point of purchase for repair by a qualified engineer. Opening and tampering with the units may invalidate their guarantee. • Do not expose the units to extreme and sudden temperature changes, this may lead to rapid changes in forecasts and readings and thereby reduce their accuracy.
