2 • Immediate update ( every 4 second s!) of all y our outdoor data measured from the tran smitters (note: 4 second may v ary while updating) • WWVB Radio-controlled time w ith manual setting opti.
3 QUICK SET-UP GUIDE Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries. 1. Have the intelligent w eather station and remo te temperature/humidity sensor 3 to 5 fee t apart. 2. Batteries should be out of both the intelligent weather station and remote temperature/humidi ty sensor units for 10 minutes.
4 87 feet. Factoring i n the 10 foot room , this leaves a max imum of 77 feet of remaining signal range. This allowance is typically enough for a frame wall w ith non- metallic siding; how ever certain materi als can reduce range even further.
5 The intelligent weather sta tion uses 3 x AA (alkaline recomm ended) batteries. When the batteries need to be replaced the low battery symbol w ill appear on the LCD (or replace the batteries annually). To install and replace the batterie s, please follow the steps below: 1.
6 ABOUT WWVB (Radio Controll ed Time) The NIST (National Institu te of Standards and Technology—Time and Frequency Division) WWVB radio station is lo cated in Ft. Collins, Colorado, and transmits the ex act ti me and date signal continuously throughout the United State s at 60 kHz.
7 SET key • Press and hold the key to enter manua l setting modes: LC D contrast, 12/24 hour time display, time zone, day light saving time ON/OFF, manual time setting, calendar, WWVB ON/OFF, ºF/º.
8 • Reset max/min record ALARM ke y • Enter the weather alarm time setting mode • Set next weather al arm in weather ala rm setting mod e LCD SCREEN The LCD screen is spli t into 6 se ctions dis.
9 * When the signal fr om the remote tem perature/humidity sensor is successfully received by the intelligen t weather station, thi s signal reception will be switched on. (If not successful, the i con will not be shown on LCD) So the user can easily see w hether the last recep tion is successful (icon on) or not (icon off).
10 • Relative pressure value setting • Language display setti ng LCD CONTRAST SETTING The LCD contrast can be set wit hin 8 levels, from LCD 1 to LCD8 (default setting is LCD 5): 1. Press and hold the SET key for about 4 seconds until the digit start flashing.
11 2. Use the MAX/+ or MIN/- key to set the time zone. The MAX/+ key increases the v alue and the MIN/- key decreases the value in consecutive 1 hour intervals. 3. Press and release the SET key to confirm selection and to enter the Daylig ht saving time On /Off settin g .
12 The unit will still try to receive the WWVB signal betw een 0:00 and 6:00 am every day despi te it being manually set, if the WWVB reception function has been set ON. When it doe s receive the signa l, it will change the manuall y set time into the received time.
13 In area where rece ption of the WWVB time is not possible, the WWVB time reception function can be turned OFF. The clo ck will then w ork as a normal Quartz clock. (D efault setting is ON). 4. The digit “ON” will start flashing on the LCD. 5. Use the MAX/+ or MIN/- key to turn OFF the time reception function.
14 Digit flashing 2. Press and release the SET key to confirm selection and to enter the Relative Pressure Value setting . Note : The default reference pressure v alue of the barome ter is 29.
15 The language for the calendar and “Intelligent” weather information display can be set to view in German ( D), French (F), Italian ( I), Spanish (S) & English (E) Default se tting is Eng lish. To set another language: 1. Use the MAX/+ or MIN/- ke y to set the desired language.
16 INDOOR RELATIVE HUMIDITY AND INDOOR TEMPERATURE: The indoor temperature and humidity data are automatically updated and displayed in th e second sectio n of the LCD.
17 The WS-9020U is able to r eceive signals from 3 remote temperature/humidity sensors (T X28U-IT). These extra transmitter s can be purchased throu gh the same dealer as this unit TO SET-UP OF MULTIPLE SENSORS 1. Remove all the batteries from the receiver and sen sor(s) and wait 60 seconds.
18 IMPORTANT: Transmission problems will arise if the setting for multiple sensors is not followed as described above. Should transmission problems occur, it is necessar y to remove the batteries from all units and start again the set-up from step 1.
19 2. While the outdoor MIN/MA X humidity and tempera ture date is being displayed, pr ess the CH key . The display w ill toggle between the differe nt channels MIN /MAX data. Note: For example, when the MIN outdoor te mperature data is d isplayed and the MAX/+ key is pr essed, MAX data outdoor temperature will be displayed.
20 Defau l t alar m va lues : Low 32ºF Temperature alarm High 86ºF LOW OUTDOOR TEMPERATURE ALARM SETTING Note: The outdoor temperature alarm can only be se t for channe l 1 transmitter. To set the LOW outdoor temperature alarm (de fault OFF): 1. Press and hold the ALARM key for about 3 seconds to enter the alarm setting mode.
21 1. The On/ Off icon is flashing . Press the MAX/+ o r MIN/- key to activate the alarm ON/OFF . 2. Press the SET key to enter the alarm value setting (alarm v alue flashing) 3. Use the MAX/+ or MIN/- key to set the alarm value. 4. Press the SET key to confirm and enter the HIGH outdoor temperature alarm setting.
22 can set the thresholds for the o utdoor temperature to +104°F (+40ºC) (high) and +14ºF (-10°C) (low), while only enabling the high alarm and disabling the low alarm (i.e. temperatures < +14 ºF (-10°C) won’t trigger alar m, but temperatures > +104ºF (+40°C) will).
23 Sunny Cloudy with sunny intervals Cloudy Rainy For every sudden o r significant change in the air pres sure, the weather icons will update accordingly to represent the change in weather.
24 Note: After initial set up of the intelligen t weather station w ith the setting of the relative value, read ings for weather forecasts sho uld be disregarded for the next 12-24 hour s.
25 The reference relative air pressur e can be se t between 28.35 to 30 .72 inHg (960 to 1040hPa). See “ Relative pressure value setting ” in manual setting. BAR GRAPH DISPLAY You may select to display the history of the air pre ssure in the form of a graph consisting o f vertical bars on the intelligent w eather station LCD.
26 At every full ho ur the current air p ressure is used as a basi s for the display of a new graph bar . The existing grap h is then mov ed one bar to the left. Note: For accurate barometri c pressure trend , the intelligent w eather station should operate a t the same altitude .
