- Programmable alarm cababilities at various weather conditions, e.g. danger of frost, storm, adverse air pressure or temperature tendencies, e.g. at sea or in the mountains or as an indication for the so called bio weather.
- All important weather informations are simultaneously displayed on the LCD, making it unnecessary to perform any special handling of the device to recognize the present weather.
- Several Base Stations can be operated simultaneously in order to display the sensor data at various places at the same time. Additional Base Stations can be ordered optionally.
Please read this Operation Manual carefully and completely before first setup in order to avoid functional disturbances and mishandling. Especially observe the notes on mounting and calibration of the measurement sensors.
The indoor and outdoor sensor system of the Weather Station works by exclusive use of remote data transmission. Remote sensors can thus be placed and mounted as far as 330 ft (100 m) from the Base Station in open field (strongly depending on the local environmental conditions). The outdoor sensors get their operating power from integrated solar cells. Please therefore carefully observe the notes on placing and mounting of these components in order to guarantee regular function of the total system.
Note! Please note that for operation of the Weather Station there is at least one Remote Sensor necessary since the Base Station itself does not contain any sensors.

6. Description of Measuring Devices (Sensors)
The sensor concept of the Professional Remote Weather Station consists of two sensor groups. For operation of the Weather Station a Remote Indoor Sensor is generally necessary. It transmits a fixed data telegram determining the display of temperature and humidity in the display section for the indoor values in the upper left part of the LCD. The sensor is immediately operable since addressing is only necessary in very rare exceptional cases.
Mounting example of
This addressing is only necessary if – within the sensor’s transmission range (up to 330 ft (100 m)) – two Base Stations with respectively assigned Indoor Sensors need to be operated (Base Station 1 showing the data of Indoor Sensor 1, Base Station 2 showing the data of Indoor Sensor 2). The Rain Volume Sensor as well as the Wind Sensor also have fixed addressing and belong to this group since their measured values too have their fixed location in the display.
The second group of sensors are the optionally obtainable types WS 7015-22, WS 7015­27, WS 7015-28 as well as the Remote Outdoor Sensor (included with basic shipment). These sensors transmit their data signal to be displayed in the outdoor section in the upper right part of the LCD. It is possible to operate up to 8 sensors which can be selected through the sensor selection in the display. It is thus necessary to assign a respective address to each sensor determining their fixed location in the upper right display section. Therefore please observe for these three types in the notes on addressing.
Remote Indoor Sensor
The Remote Indoor Sensor included with the basic shipment requires two Type Mignon AA, IEC LR6, 1.5V batteries for operation. It contains one respective sensor for temperature, humidity and air pressure. The data of the Remote Indoor Sensor generally appear in the indoor display section in the upper left part of the LCD. Besides indoor temperature and indoor humidity it measures the air pressure prerequisite for the display of air pressure, air pressure tendency, weather tendency and air pressure history.
Remote Wind Sensor
The Remote Wind Sensor simultaneously acquires wind direction and wind strength at its mounting location. It is operated by a solar cell with a battery backup during darkness and provides addressing which cannot be altered by the user.
Remote Rain Volume Sensor
The Remote Rain Volume Sensor also works with solar power supply and provides addressing not alterable by the user. The funnel has a 5.12 in (130 mm) diameter, which represents an area of 20.45 in
2
, the calculation base for the rain volume.The amount of water flowing through the funnel initiates a number of pulses. These pulses are converted to in or mm in the Base Station and then displayed.
Remote Outdoor Sensor
The Remote Outdoor Sensor included with the basic shipment allows the transmission of the temperature and humidity values at its mounting location. This sensor can be addressed freely for display within the outdoor display section in the upper right part of the LCD (see Display Overview). By default all Remote Outdoor Sensors are set to Sensor 1. Individual addressing is however possible.
7. Mounting
Base Station
The Base Station can be placed on any smooth surface (e.g. table, bookshelf, etc.) by pulling out the foldable stand or wall mounted at any desired location by means of a hanging hole at the back of the device.
Important Note! It is recommended to check that the 433MHz signals are properly received before permanently mounting the Professional Weather Station (drilling of holes, etc.). Should the Weather Station not pick up signal from the desired location a slight relocation will help in most any case. Once the signals are received, the system can be mounted permanently. Mounting is but a preparation for the setup. Just before the final setup of the Base Station the magnets have to be placed into the sensors.
Recommendation! In order to test all sensor functions at first setup the sensors can prior to mounting be placed on a smooth surface (table, etc.) and put into operation (see Item 8 Setting Up).

Solar Cell
Mast
Mounting takes place either to a mast or at the upper rim of a wall. It is important to mount the device in such a way that the solar cell in the sensor housing is pointing in a southerly direction. It is further important to mount the device in a zone not prone to wind shadow, i.e. the wind must be allowed to travel freely about the sensor from all directions. Remove the transport protection from the sensor head and make sure that weather-vane and wind wheel can move freely and easily. Put sensor head, holding tube and mast/wall holder together and fix the components by use of the supplied screws. For basic mounting the Wind Sensor must be pointing exactly in a southerly direction (solar cell to the south) in order to provide an exact northerly reference point for the evaluation electronics.
Note! An exact southerly alignment of the sensor respectively its solar cell is very important since this alignment will provide the reference point for the Wind Direction Sensor. In order to obtain correct measuring values exact perpendicular mounting of the sensor to the mast must be observed. Axial stress to weather-vane and wind wheel should be avoided.
Remote Indoor Sensor
Mount the sensor to its desired location. Keep in mind that the sensor is not designed to operate outdoors or in rooms prone to excessive humidity. Data of the Indoor Sensor are
generally displayed in the display section in the upper left part of the LCD. After insertion

of the batteries the sensor is immediately operable.
Remote Outdoor Sensor
The mounting of the sensor should take place anywhere to the west or north since temperatures in meteorology usually are measured in the shadow. It can however be mounted at any other location if desired. It simply must be observed that the solar cell powering the sensor does have to point towards the light in any case. The sensor must not be obstructed by any close impediments such as leaves or the like since this will prevent the solar cell from efficiently powering the sensor. A thinkable mounting location would e.g. be a spot beneath the roof extension. The sensor is designed for wall or mast mounting, which can be performed in the following way: Either mount the wall holder of the sensor in an exact perpendicular position to a wall by means of four screws or to a mast by use of the supplied mounting bracket. Place the sensor into the wall holder and secure both parts by use of the supplied screw. Ensure that the large protective hood lies on top and the solar cell is pointing towards the light.
During darkness and periods of bad weather with a relative lack of sunlight an internal battery system buffered by the solar cell will take care of the sensor’s power supply.
Remote Rain Volume Sensor
Generally mount the Remote Rain Volume Sensor with its solar cell pointing in a southerly direction. The Rain Volume Sensor must be securely mounted to an exact horizontal surface by means of its mounting holes in the bottom part of the housing. Prior to this remove the upper part from the lower portion by pressing and turning the upper part clockwise with regard to the bottom part. Remove the transport protection from the seesaw in the lower part of the sensor and check by tilting that the seesaw can move freely and easily to its both endpositions. A cavity in form of a „T“ in the bottom part of the Rain Volume Sensor can be filled with water and thus allows an exact horizontal alignment without any other auxiliary means. Fill a small amount of water into this cavity and align the bottom part of the sensor by principle of a spirit-level. After marking the exact mounting position the water can be removed. Observe the southerly alignment for the solar cell. By doing this the short leg of the engraved spirit-level must point to the north.

In order to reach the best possible remote transmission (high transmission range) it is recommended not to mount the Rain Volume Sensor too close to the ground. Mounting the unit at a height of appr. 3.3 ft (1 m) also reduces the danger of pollution (especially the solar cell). Observing the correct polarity insert the color
marked magnet into the holder.
Important Note! In order to avoid start-up problems make sure that the color marked magnet is inserted observing the correct polarity as shown in
the Imprint
the illustration opposite.
After securely screwing the bottom part of the sensor to the mounting surface replace the upper part as follows: On the side of the counting seesaw for the rain volume in the bottom part of the sensor there is a bar magnet mounted in the center initialising the counting pulses for the electronics. The top of the housing has now to be replaced in such a way that the solar cell is also placed on the side of the magnet with the electronics part also directly opposite and the three retaining hooks exactly fitting into the holders in the bottom part. Turn the upper part carefully in a counter-clockwise direction until the retaining hooks tightly lock into place. The Remote Rain Volume Sensor is now operable. For testing purposes very slowly pour a small amount of water into the funnel. The collected amount will later be computed and displayed in inch or mm in the Base Station.
Note! When mounting the Remote Rain Volume Sensor make sure that the collected water can drain off easily without any obstruction (even in case of sleet or snow).
8. Setting Up
Before setting up, the Intended Use as well as the various Safety Notes and the Specifications have to be closely observed. Make sure before setting up that the device does fit the intended purpose for which you want to use it.
Activating the Sensors
The Outdoor Sensors for wind measurement, acquisition of rain volume and measurement of outdoor temperature and humidity are for power supply equipped with a solar cell as well as a Lithium buffer battery for periods of darkness and bad weather. In oder to protect the precious batteries from over-discharging during long storage periods without incidence of light to the solar cell (e.g. when packaged), the power supply is only activated by means of a small magnet which must be inserted into the sensor from the outside prior to first setup. The magnet belonging to the respective sensor should thus only be inserted a short time before the Base Station is put into operation.
Important Note! In order to unambiguously assign the sensor data the Base Station should only be put into operation after all sensors have been operating for at least 10 minutes.
This point is important since all sensors will at first work in a test mode for up to 10 minutes after the supply power has been applied (insertion of magnets into the Outdoor Sensors and insertion of batteries into the Indoor Sensor). During this test phase the data transmission takes place at a 4 second (approx.) pace rather than the 3 minute scan applying lateron.
As with the Remote Outdoor Sensor the magnet for activation of the system must be inserted into an opening provided for at the back of the unit. The magnet must tightly be pressed into the opening and will stick out by appr. 4 mm. The activation of the Remote Wind Sensor also takes place by inserting a small magnet into the opening provided for. In this case the magnet holder is placed above the holder tube mounting (opposite the solar cell). In order to insert the magnet into the Remote Rain Volume Sensor the upper part has first to be removed by pressing and turning the upper part in a clockwise direction with regard to the lower part. In the center of the electronics casing there is a holder for the bar magnet activating the electronics. Insert the color marked magnet according to its correct polarity into the holder (also see Page 34). After pressing the magnets into their holders the sensors will take up data transmission.
The Remote Indoor Sensor needs two Mignon AA, IEC LR6, 1.5V batteries for operation. To insert the batteries the battery compartment needs to be opened. Insert the batteries observing the correct polarity in accordance to the engraved polarity marking in the battery compartment. Replace the cover of the battery compartment.
Approximately 12 minutes after activating the last sensor, insert four Mignon AA, IEC LR6, 1.5V batteries into the Base Station observing the correct polarity. Upon inserting the batteries into the Base Station a short initializing phase takes place during which all segments of the LCD will shortly be displayed. Following this segment test the Base Station will automatically switch into a so called test mode during which each data reception is shown on the display and acknowledged by the sound of a signal tone. For better distinction there generally is only the display of the sensor received last while the data of all previously received sensors are being erased. The perfect reception of all sensor data can thus be checked quickly and easily.
Note! Under critical reception conditions this test mode also helps to find the best possible location for good reception. To do this the respective sensor simply must also be set to its test mode in order to transmit a data telegram every 4 seconds. In order to activate this test mode the batteries from the Remote Indoor Sensor and the magnets from the Outdoor Sensors have to be removed and re-inserted after a waiting period of at least 60 seconds.
After approximately 30 minutes the Base Station will automatically terminate this test mode and switch over to its normal reception mode. By pressing any function key the test mode can be terminated earlier at any time.
Important Note! For unambigious assignment of the sensor data, the test mode at the Base Station should generally not be terminated as long as there is any sensor still in test mode.
After the test mode has finished (up to twenty minutes), it is necessary to set the time and date. Press the two arrow keys (←←←) and (→→→→) and the "Calibr.“ Key at the same time; "0000 inHg“ will be displayed. Press the left arrow key twice to enter the time and date mode. Press the "-“ key to advance the hour (please note the AM/PM setting), press the "+“ key to advance the minutes, press the "Unit“ key to advance the month, and press the "Sensor“ key to advance the day. It is important to set the time and date after set up of the sensors to avoid problems.
For easy setup the Base Station can also be carried close to the mounting locations of the sensors. This way the correct data transmission of the sensors can be checked. The data of mounted sensors will after the test phase be transmitted at an approximate 3 minute pace and will be displayed in the various display sections of the LCD. After all sensors have been received, their function can be tested as follows:
Indoor and Outdoor Temperature Sensors can be slightly warmed or cooled. A change of temperature and humidity will be seen on the base station. This however may take up to 3 minutes.
The wind wheel of the Remote Wind Sensor should be turned at a moderate speed for one to two minutes. The weather-vane of the sensor should be pivoted. The changes will also become visible on the LCD.
To test the Remote Rain Volume Sensor at first the "Rain" key can be pressed several times to get "Total“ rain display in case other rain records are being displayed. The display "Total“ will appear. Now press the "Reset" key for about 3 seconds until a beep tone sounds. Very slowly pour a small amount of water into the funnel, observing that there is no slack water in the funnel at any time (this test should preferrably be performed in kitchen or bath to avoid inconvenient splashes). Latest after 3 minutes the display of the rain volume will be updated.

10. Operation
After the installation of the Remote Sensors and the following setup of the Base Unit (test mode of the Base Unit should generally be terminated after the test mode of the last sensor) the transmitted and computed data will show on their respective display sections on the LCD. If this is not the case please observe the notes on debugging on Pages 46-
47.
Note! Please note that data can only be displayed if there is a respective sensor installed. E.g. without a Rain Volume Sensor there will be no display of rain volume.
Since all relevant data is simultaneously displayed in the first place, operation will essentially be limited to simple selection of further sensors or further weather data by repeated pressing of the respective function keys.
Item "Operation“ solely pertains to operation in Normal Mode with the large key imprints being applicable.
Programmable functions are thoroughly covered in Item "Programming Mode“ with the small key imprints being applicable.
Indoor
In normal operating mode the indoor display in the upper left of the LCD displays the temperature and humidity at the location of the Indoor Sensor.
By once pressing the "Indoor" key the Dew Point will be displayed. The Dew Point is that point in temperature at which condensation of humidity begins and the so called "Dewing“ takes place, i.e. the humidity is condensing and will precipitate in liquid form. So the dew point for e.g. air with a water-vapour content of 17.4 g/m
3
lies at a temperature of 68ºF (20°C). If the dew point for water-vapor drops below 32ºF (0°C), the precipitation will take place as snow or hard-frost.The dew point depends upon the concurrence of a certain air pressure, temperature and humidity at the same time.
One more pressing of the "Indoor" key will lead back to the normal temperature display.
Wind Pressing of the "Wind" key leads to the Change of Units for the Display of Wind Strength respectively and the change from the display of the wind strength to a Digital Display of Wind Direction in 5° steps within the compass (digital display field). The
order of changes and displays will be as follows:
- Wind Strength in mph
- Wind Strength in knots
- Wind Strength in m/s
- Wind Strength in km/h
- Wind Strength in Beaufort
- Display of Wind Direction in place of Wind Strength

Rain Pressing of the "Rain" key successively leads to the display of the Rain Volume of the Last Hour (interval between the 30
th
minute and the 30th minute of the respective hour), the Rain Volume of the Last 24 Hours (interval between 7.30h and 7.30h of the respective day) and the Total Rain Volume (since start of measurements at Setup and since last Reset) in the right center of the LCD. Times and time intervals are in conformity with the International Rules for Professional Weather Services.
Basic display: Total Rain Volume Press once: Rain Volume of the last Hour Press twice: Rain Volume of the last 24 Hours Press three times: Return to Total Rain Volume (see illustration at right)
If the "Reset" key is pressed for appr. 2 seconds during display of the Total Rain Volume, the accumulated value of the Total Rain Volume will be erased and reset to zero. Time and date of the reset will be stored in the weather station’s memory. Time and date of the last reset can at any time be displayed by briefly pressing the "Reset" key.
If during switching of the Rain Volume Mode from Total to 1h or from 1h to 24h the "Rain" key is held down for a longer period of time, the display will switch to an accumulating counter. This mode of operation is indicated in the display by the symbol "||" in front of the numerical value. Now e.g. during a rain shower the "running up“ of the 1h resp. 24h counter can be observed.
Minimum/Maximum Function
The Min/Max function allows the display of the minimum and maximum values of all measurements since the last reset of the Min/Max memory. If desired, the time and date of the appearance of the respective minimum and maximum values can also be displayed.
Display of the Minimum/Maximum Values
Press once: Display of all Minimum Values Press twice: Display of all Maximum Values Press three times: Return to Display of the Current Values
During simultaneous display of all minimum or maximum values there will for the present be no additional display of time and date. There will also be no weather symbols, no display of air pressure tendency and no air pressure history. Instead there will be the respective display MIN or MAX in the right center of the LCD. If the clock not been manually set, then there will be no storage of any minimum or maximum values.
Display of Single Values with their respective Time and Date
If during display of the minimum or maximum values one of the Arrow keys (←←←) or (→→→→) is pressed, nothing but the minumum or maximum value of the indoor temperature with its respective assigned time and date will be diplayed.
Now by use of the Arrow keys and the Min/Max key each single minimum or maximum value with its assigned time and date of storage can be selected. Additionally with the maximum wind strength the wind direction at the time of storage will be displayed.
Note! During this display mode all other sections of the LCD will stay invisible.
Selective Reset of Stored Values
If during display of any selected minimum or maximum values the "Reset" key is pressed for appr. 2 seconds, the respectively assigned minimum or maximum values will be erased and reset.
Reset of all Stored Values
If during display of the minimum or maximum values the "Reset" key is pressed for appr. 2 seconds, all stored values will be erased and reset.
Alarm Function
As soon as any measurement of the Weather Station exceeds or falls below a set alarm value, the air pressure tendency display, air pressure history, weather icon and wind direction display will generally be switched off. The display then only shows the particular section of the LCD where the value has fallen outside of the set alarm window. The symbol "ALARM" will also be displayed. If this does apply to more than one display or measurement section, their display will also be shown in case of alarm. By use of the "Sensor" key the alarm settings of the Outdoor Sensors can be scanned. The alarm arriving first will including its assigned sensor identification be shown in the display. In case of alarm the Weather Station will stay in the "Alarm“ display mode until the "Alarm" key is pressed and the display has thus returned to the display of their current values. In case of alarm there will additionally be an acoustic signal, which is composed of five single tones. The signal will be repeated every 30 minutes for a total time span of max.
7.5 hours. The alarm will be terminated when the values of the respective measurement section have returned to within their programmed value range as well as after additionally pressing the "Alarm" key (Return to the display mode for the current data).
Sensor Selection
The "Sensor" key allows in all operating modes of the Weather Station the selection of the Outdoor Temperature/Humidity Sensors. The selected sensor will in the "Sensor“ display section be displayed with its assigned identification number.
Outdoor
In normal operating mode the outdoor display in the upper right of the LCD displays the temperature and humidity at the location of the Outdoor Sensor selected by use of the "Sensor" key.
By once pressing the "Outdoor" key the Dew Point will be displayed. By twice pressing the "Outdoor" key the temperature display in this section will change to the display of the Windchill Equivalent Temperature (Perceived Temperature). Windchill display will of course only be possible if a Remote Wind Sensor is part of the Weather Station System. One more pressing of the "Outdoor" key will lead back to the normal temperature display.
The Windchill Equivalent Temperature (Perceived Temperature) is a fictive temperature which is perceived by man under certain conditions instead of the really measured current temperature and which can be taken to determine the comfort stage of a person wearing suitable clothing at a certain temperature and wind strength. These conditions are represented by a temperature of 91.4ºF (33°C) and a wind strength of 5.816 mph (2.6 m/s). Windchill is defined as the cooling effect on bare human skin at an assumed constant skin surface temperature of 91.4ºF (33°C).
The "Perceived Temperature“ is approximately comparable to the so called "felt“ or "sensed“ temperature, which is additionally considering the radiation effect of the sun, light reflection of the clouds, wave length of light, etc.
This display does only make sense however if the Remote Outdoor Sensor responsible for this display is placed at an adequate location. It is e.g. possible to place such a sensor at a roofed terrace which is exposed to outdoor temperature and wind. Windchill display will of course only be possible if a Remote Wind Sensor is part of the Weather Station System.
11. Programming Mode
In programming mode all the minimum and maximum value settings for the alarm functions can be performed. Please observe that for this mode only the imprints below the functions keys will apply. If the "Store" key is pressed or no key is pressed for about 60 seconds the device will automatically switch back to its normal operating mode.
In order to enter the Programming Mode both Arrow keys (←←←) and (→→→→) must be pressed simultaneously. The display will now show the set minimum alarm value. Weather icons, air pressure tendency display, air pressure history and compass will be switched off. By once pressing the "Min/Max" key, the maximum alarm value will be displayed. By again pressing the "Min/Max" key, the system will return to the display of the minimum alarm value. The alarm values, such as for exceeding or falling below a certain ground temperature, for a certain wind strength, etc., can now be set in Programming Mode. By pressing the "Store" key the Programming Mode can be left.
Setting of the Minimum/Maximum Alarm Values
By use of the Arrow keys (←←←) and (→→→→) and possibly the "Sensor" key select the desired measuring point or measuring value respectively. All other displays will stay switched off.
Minimum/Maximum Selection
In this mode the mimimum or maximum values can be arbitrarily set by use of the "Min/Max" key. The key functions as well as the functional sequences are identical to the ones in Item Minimum/Maximum Function above. If desired, it is this way possible to either firstly set all minimum values, followed by all maximum values or immediately set all assigned minimum and maximum values to each respective measuring point. Only one maximum value can be set for the wind strength. In order to enter this value a switch from Min to Max must be performed.
Setting of Values
By use of the "+“ and "–“ keys the desired numerical values can now be set. By holding the keys down, the device will automatically count up or down. There is the additional possibility to speed up the counting by a factor of 10 by simultaneously pressing the "Fast" key and either the "+" or the "–" key.
12. Calibration
All one time settings will be performed in Calibration Mode. This applies to the Altitude Correction for the Barometric Air Pressure and the Calibration of the Rain Volume Sensor as well as the setting of the desired Units for Air Pressure and Rain Volume. The time and date can also be set in Calibration Mode. Further, if desired, the addresses of the Indoor Sensor to be received, of the Wind Sensor and of the Rain Volume Sensor can be changed in this mode. The Calibration Mode can be entered by simultaneously pressing the (←←←), "Calibr." and (→→→) keys. The respective display section can then be reached by use of the (←←←←) and (→→→→) keys.
Setting of the Altitude Correction for the Barometric Air Pressure
After selecting the air pressure display section the altitude of your location with regard to sea-level (H.a.SL – Height above Sea-Level) can directly be entered in Meters (values from 0 to 1999 m possible) by use of the "+" and "–" keys and possibly the "Fast" key. The setting of display units in hPa or inHg is of no significance for the Altitude Correction for the Barometric Air Pressure. By pressing the "Store" key the set value is stored and the display will return to the normal operating mode.
Calibration of the Rain Volume Sensor Note! The Rain Volume Sensor by design and manufacturing already offers a very high accuracy and will for normal operation not require any special calibration. Calibration may only be necessary for extremely high accuracy demands.
Before starting the calibration of the Rain Volume Sensor any possibly already accumulated rain volume value has to be erased and reset to 0 in normal display mode according to Item Rain of this manual (leaving the Programming Mode). Following this procedure pour exactly one Liter of water during an arbitrary time span very slowly into the funnel of the Rain Volume Sensor.
Caution! Fast pouring will corrupt the measuring results! Pour the water so slow into the funnel, that there is no slack water in the funnel at any time.
Recommendation! In order for the water not to run too fast into the funnel, thus causing a faulty calibration, place a small cup made of synthetic material into the funnel. Prepare the cup by piercing a small hole into the bottom using a sharply pointed tool. The water will now enter the funnel very slowly drop by drop.
Because of the 5.118in (130mm) diameter of the funnel, representing an area of 20.574
2
in
(0.0133m2 ), the amount of 1 Liter of water will yield a nominal rain volume of 2.97 in. After the entire amount of water has run through the funnel the actual value (displayed value) will show on the display, in the ideal case 2.96 in. The ratio of Target Value to Actual Value will yield the Calibration Factor. Since this calibration factor may have already been entered at an earlier date, it has to be included in the calculation. The new Calibration Factor can be computed in the following equation:
New Calibration Factor =
Target Value (e.g. 2.96 in) x Old Calibration Factor
Actual Value (Display after passing 1 Liter of Water)
The old calibration factor can be viewed by simultaneously pressing the (←←←) and (→→→→) keys as well as the "Calibr." Key in Calibration Mode. Select the display field for the Rain Volume Sensor by use of the (←←←) key. Correct the calibration factor to its new value by use of the "+" and "–" keys and possibly the "Fast" key. By pressing the "Store" key the set value is stored and the display will return to the normal operating mode.
Change of Units
If the "Units" key is pressed in Calibration Mode, the display section "Rain" will allow the selection of the units inch or mm and the display section "Air Pressure" will allow the selection of the units inHg or hPa, and the display section "Indoor temperature“ will allow the selection of the units ºF or ºC.
Manual Time Setting
To do so press the Arrow (←←←) key twice in Calibration Mode. The display will show time and date only. Setting is then performed according to Table 1. After entering the time and date the "Store" key must be pressed.

Addressing of Remote Sensors WS 7015-22, WS 7015-28 (optionally) and Remote Outdoor Sensor
The outdoor sensor concept allows the simultaneous operation of up to 8 outdoor sensors. Their data are displayed in the upper right display section for the outdoor values. Each sensor in the system is assigned a sensor address, allowing the receiver to integrate the sensor into the overall system free from interference. By default the Remote Outdoor Sensor included in the shipment is set to be Sensor 1, while the types WS 7015-22 and WS 7015­28 are both set to be Sensor 2. The programmable assignment can be seen from opposite illustration. The addressing can be performed by the user by means of coding bridges (jumpers) on the wiring side of the sensor‘s PCB. To do this the protection hood has firstly to be removed by unscrewing from the Remote Outdoor Sensor and then the housing must be opened by removing the screws on its back. Both types WS 7015-22 and –28 only need to have their back covers unscrewed. Following this the coding bridges can be set according to the addressing table opposite.
Change of Base Address for Sensors with fixed Assignment
Setting of addresses for the Remote Indoor Sensor, Remote Rain Volume Sensor and Remote Wind Sensor is not required under normal operating conditions. Multi functional operation is a special feature, allowing to generally operate an arbitrary number of Base Units within the transmission range of the Remote Sensors. One Base Station can be placed in the living room, one in the office, etc., all displaying the same data.
If in every room, in which a Base Station (Display Unit) has been placed, the indoor temperature of this particular room needs to be displayed on the upper left section of the LCD, then the indoor sensors for temperature/humidity and air pressure need to be assigned different base address according to the illustration opposite. In order for the Base Station to exclusively receive its assigned sensor here also a respective address has to be set. To change the base address in Calibration Mode the (←←←)key must be pressed three times and the desired base address selected by use of the "Indoor" key. The base addresses of the Wind Sensor and the Rain Volume Sensor can also be changed in this operating mode which however is only necessary in very rare cases. A
change of address is only required if two neighbouring Wind Sensors or Rain Volume Sensors are placed within the reception range of the Base Station. The base address of the Wind Sensor and the Rain Volume Sensor can only exclusively be changed by the manufacturer, thus requiring the units to be shipped back to the manufacturer, if necessary.
Note on Storage of Solar Powered Outdoor Sensors
These sensors receive their operating power from a solar cell which also powers an internal battery to be used during periods of darkness and bad weather. If any such sensor is taken out of operation for a longer time period without any light there still is no danger for the internal battery as long as the small magnet required for activation of operating power has been removed. This way a sensor in its packaging can be stored for several years.
13. Battery Change
Remote Indoor Sensor, Remote Sensors WS 7015-22, WS 7015-27 and WS 7015-28
The batteries in these sensors have a life expectancy of up to 3 years (Alkaline Batteries). They have to be changed, if the display of the respective sensor in the base station fails to appear for a time period exceeding 24 hours and any general and longer lasting interference of the transmission path is out of the question. The latter can generally be recognized if the data transmission of other sensors being close to the one missing also do not work properly (see Item Interferences). Batteries can be changed by opening the battery compartment of the sensor, removing of the used-up batteries and replacing them with new Type Mignon AA, IEC LR6, 1.5V batteries under observance of the correct polarity as marked in the battery compartment. After replacing of the battery cover the sensor is ready to operate again. Latest after the Base Unit has performed its standard search routine (see Item Interferences), the data of the sensor must again appear on the display.
Base Station
The Base Unit indicates low running batteries by a battery icon in the top portion of the LCD. Since stored data may be lost during battery change it is recommended to call off and note all data, if required, prior to battery change. Then open the two battery covers on the back of the casing, remove the used-up batteries and replace them with four new Type Mignon AA, IEC LR6, 1.5V batteries under observance of the correct polarity as marked in the battery compartment.
The end user is obliged by law (Battery Regulations) to properly dispose of all used-up batteries and accumulators (button cell to lead-acid accumulator). Disposal of such items through the garbage is strictly forbidden. Used-up batteries can be returned to all municipal recycling centers which are obliged to accept such items.
Please participate in the preservation of the environment!
Note! Other parts of the system do not require any battery changes since they are powered by solar cells. Integrated buffer batteries will cover periods of darkness and bad weather.
14. Interferences
If any sensor has not been received for a period of 12 hours, its display will cease to show its values on the LCD. If by temporary disturbances of the transmission path the synchronization between sensor and base unit is interrupted (transmission only takes place in a very small time window), the base station will scan all sensor transmitters for 6 minutes at 8.00h a.m. and 6.00h p.m. every day. Latest after that time a temporarily interrupted reception should be resumed.
Possible interferences preventing correct display of transmitted measurement values:
Undefined values after setting up.
In order to immediately receive defined data and ensure the correct assignment of all data telegrams to their display section make sure, that the test mode of the Base Station is only be terminated after all sensors have ended their test phase.
No reception – distance between transmitter and receiver too long.
Reduce distance between transmitter and receiver. Use Repeater (WS-7015-12) to extend transmission distance.
No reception – highly shielding materials between transmitter and receiver (thick walls, steel concrete, isolating aluminum foil, etc.). Find different location for transmitter and/or receiver. See also Item Transmission
Range.
Low batteries in transmitter or receiver.
Change batteries. Observe low battery indicator.
Transmitter is superposed by interfering sources (e.g. wireless radio, headset, speaker, etc.). Remove interfering source. Find different location for transmitter and/or receiver. Has no reception taken place for the last 12 hours, the respective measuring point is shut down and no measuring value will show, since the system is assuming a sensor no longer in existence. In order to save battery power there will be no more reception attempts. Every day at 8.00h a.m. and 6.00h p.m. the receiver will automatically start a new synchronization whereby a sensor not received for more than 12 hours will be incorporated into the system again.
Note! Every newly added Remote Sensor (e.g. after a battery change) will automatically be entered into the system and its respective data will be displayed.
Quite frequently interferences are only of a temporary nature (e.g. R/T operation) or can easily be overcome. If there are wireless headsets, remote babysitters or other devices working on a 433MHz basis in your house or vicinity, their switch-on time is mostly limited.
Furthermore most of these devices allow the change to an interference-free frequency. Such measures will effectivelly overcome interferences.
Remote Sensor does interfere with other devices in the 433MHz range.
The transmissions of the Remote Outdoor Sensor can temporarily (for about 200 ms every 3 minutes) interfere with other devices working on the same channel. These interferences are of very short duration and can thus be neglected. If possible, the channel should be changed at the respective device.
15. Transmission Range
The transmission distance in open field with free range of sight between transmitter and receiver reaches under optimum conditions 330 ft (100 m). Walls and even steel concret constructions will be penetrated at a considerable loss of transmission distance. A loss of distance can have the following reasons:
- High frequency interferences of any kind.
- Constructions of any kind or vegetation.
- Especially for the Wind Sensor the transmission distance can be influenced by metal
roofs or aluminum foil roof isolation.
- The distance of transmitter and receiver to conducting planes or object (including the
human body or the ground) does influence the transmission characteristics and thus the transmission distance.
- Broad band interferences in municipal areas can reach levels reducing the
signal/noise ratio over the entire frequency band, thus also reducing the transmission distance.
- Devices working at closely neighbouring frequencies may also influence reception.
- Poorly shielded PCs can irradiate the receiver and thus reduce transmission
distance.
- For extension of transmission distance the optionally available Repeater (WS-7015-
12) can be used.
16. Cleaning and Maintenance
- Clean the housing and screen of the Base Station only with a soft, damp cloth. Do
not use abrasives or solvents.
- Ensure that the Remote Rain Volume Sensor does not collect leaves or other dirt.
Remove the funnel from the Rain Sensor every now and then and clean it under running water. Also clean the seesaw of the sensor with a damp cloth and check by lightly tapping with your finger that it can move freely from side to side. Do not clean the funnel with attached bottom part of the Rain Sensor nor the bottom part itself under running water. This may bear the danger of water entering the unit’s electronic parts.
- Do not immerse the Base Station in water.
- Please do not attempt any repairs on your own. It is recommended to have repairs
only performed by trained personnel at the point of purchase. Opening or improper handling of the units will void the warranty.
17. Disposal
If the Professional Remote Weather Station happens to become inoperable and must be disposed of please do this in accordance with the valid legal regulations.
