First, insert the batteries into the Thermo-hygro transmitter. (see "How to install and replace batteries in the Thermo-hygro transmitter"). 2. Immediately after and within 2 minutes, insert the batteries into Weather station (see "How to install and replace batteries in the Weather station"). Once the batteries are in place, all segments of the LCD will light up briefly. Following the time as 0:00 and the "weather man" icon will be displayed. If these are not displayed after 60 seconds, remove the batteries and wait for at least 10 seconds before reinserting them. 48 3. 4. After inserting the batteries into the transmitter, the Weather station will start receiving data from the transmitter. The outdoor temperature/ humidity and the signal reception icon should then be displayed on the Weather station. If this does not happen after 3 minutes, the batteries will need to be removed from both units and reset from step 1. In order to ensure sufficient 868 MHz transmission however, this should under good conditions be a distance no more than 100 meters between the final position of the Temperature Station and the transmitter (see notes on "Positioning" and "868 MHz Reception"). 49 When more than one transmitter is used 1. User shall remove all the batteries from the temperature station and transmitters and wait 60 seconds if setting has been done with one transmitter before. 2. Insert the batteries to the first transmitter. 3. Within 30 seconds of powering up the first transmitter, insert the batteries to the Weather Station. Once the batteries are in place, all segments of the LCD will light up briefly. Following time as 0:00 and the "weather man" icon will be displayed. If they are not shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them. 50 4. 5. 6. The outdoor temperature and humidity from the first transmitter (channel 1) should then be displayed on the Temperature station. Also, the signal reception icon will be displayed. If this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1. Insert the batteries to the second transmitter immediate after (in 10 seconds after) inserting battery to the weather station. The outdoor temperature and humidity from the second transmitter and the "channel 2" icon should then be displayed on the Temperature station. If this does not happen after 2 minute, the batteries will need to be removed from all the units and reset from step 1. 51 7. 8. Insert the batteries to the third transmitter immediate after (in 10 seconds after) inserting battery to the second transmitter. Then within 2 minutes, the channel 3 outdoor data from the third transmitter will be displayed and the channel icon will shift back to "1" once the third transmitter is successfully received. If this is not happen, user shall restart the setting up from step 1. Note: After the three transmitters have been set up, user may need to check the readings displayed on the weather station against those being shown on the 52 transmitter displays, in order to ecognise on which channel each transmitter is being presented. IMPORTANT: Transmission problems will arise if the setting for additional sensors is not followed as described above. Should transmission problems occur, it is necessary to remove the batteries from all units and start again the set-up from step 1. 9. Once the remote data has been received and displayed on the Weather station, the DCF-77 time code reception is automatically started. This takes 53 typically between 3-5 minutes in good conditions. Note: · · · If after 10 minutes, the DCF time has not been received, press the SET key to manually enter a time initially. Daily DCF reception is done at 02:00 and 03:00. If the reception at 03:00 is not successful, then at 04:00 and 05:00 and 06:00 there are other tries, until one is successful. If the reception at 06:00 is still not successful, then the next try takes place at 02:00 next day. When this is successful, the received time will override the manually set 54 time. The date is also updated with the received time. (Please refer also to notes on "DCF-77 Radio controlled Time" and "Manual Time Setting"). 55 The Outdoor Thermo-hygro Transmitter · · · · · Remote transmission of outdoor temperature and humidity to Weather Station by 868 MHz Displays alternately the measured temperature and humidity readings on LCD Shower proof casing Wall mounting case Mounting at a sheltered place.

By pressing the MIN/ MAX key, display the stored MIN/MAX outdoor temperature and humidity, with simultaneous display of MIN/ MAX icon. 68 · · By pressing the CH key, display outdoor sensor data (up to three outdoor transmitters). The channel number 1, 2 or 3 will be shown. A signal reception symbol will be shown indicating that receiver is receving outdoor temperature. DCF-77 RADIO CONTROLLED TIME: The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in one million years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 69 kHz) and has a transmitting range of approximately 1,500 km. Your radiocontrolled Weather station receives this signal and converts it to show the precise time in summer or wintertime. The quality of the reception depends greatly on the geographic location. In normal cases, there should be no reception problems within a 1,500 km radius around Frankfurt. Once the outdoor temperature is displayed on the Weather station after initial setup, the DCF tower icon in the clock display will start flashing in the upper left corner. This indicates that the clock has detected that there is a radio signal 70 present and is trying to receive it. When the time code is received, the DCF tower becomes permanently lit and the time will be displayed. If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then please take note of the following: · Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 1.5 - 2 metres. · Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window and/or point its front or back towards the Frankfurt transmitter. 71 MANUAL SETTINGS: The following manual settings can be done in the setting mode: · LCD contrast setting · Time zone setting · Time reception ON/OFF setting · 12/24-Hour setting · Manual time setting · Calendar setting · °C/ °F setting · Weather forecasting icon sensitivity setting 72 Press the SET key to advance to the setting mode: LCD CONTRAST SETTING flashing The LCD contrast can be set to 8 different levels to suit the users needs (default LCD contrast setting i ...
