LEARNING/ REMOVING A TRANSMITTER (CHANNEL) After replacement of batteries of a particular transmitter, it is necessary to learn the transmitter again in the learning mode. On the other hand, when user want to decrease the number of transmitters to be applied, he may remove the transmitter so that the data from this channel will not be displayed in the temperature station. The below procedures describe how to “re-learn” or “remove” a channel: 1.
THE NUMBER OF OUTDOOR TRANSMITTERS TO BE SAVED INTO THE SYSTEM MEMORY Digits flashing Up to 3 outdoor transmitters can be received by the temperature station. User may decide the number of transmitter data to be saved to the permanent memory of the temperature station. For instant, user may apply 3 transmitters but set to save the data only from particular 2 transmitters. To set the number of transmitters whose data are to be saved in the system memory: 1.
On the other hand, if user has initially applied 3 transmitters but then remove the Channel 2, the temperature station will thereafter display “--.-“ for Channel 2. And if the user has chosen “Enr = 2, then data from Channel 1 to 2 will be stored in the memory, instead of Channel 1 and 3. The data stored in the memory for Channel 2 will be “--.-“. After the “Enr” number has been changed, the history data will be cleared and “mem” will be reset to “0000”.
VIEWING VARIOUS TYPE OF TEMP/HUMDITY READINGS OF A SELECTED CHANNEL: After a particular channel (the indoor sensor or one of the outdoor transmitters) has been selected by pressing the Plus or Minus key, the following modes of data may be viewed by user: a. The Max temperature and Max humidity Max icon flashing In normal display mode, press the mode key once. The maximum temperature and maximum humidity measured by the channel, and the date and time of the maximum temperature recorded will be displayed.
b. The Min temperature and Min humidity Min icon flashing In normal display mode, press the mode key two times. The minimum temperature and humidity measured by the channel, and the date and time of the minimum temperature recorded will be displayed. The “min” icon will be flashing.
c. The average value of the last 100 sets reading Average icon flashing In normal display mode, press the mode key three times. The average temperature and humidity value of the data which have been saved in the system memory will be displayed. The “avg” icon will be flashing. If the channel is not set to be saved in the system memory, no average value will be estimated and “--.-“ will be shown.
d. The dew point temperature Dew point temperature icon In normal display mode, press the mode key four times. The dew point temperature will be displayed next to the flashing “td” icon.
e. The history data sets of temperature and humidity History data icon flashing In normal display mode, press the mode key five times. The “hist” icon will be flashing and the last recorded temperature and humidity reading with the time of record will be displayed. By pressing the Minus key, the previous sets of readings which were measured at the userselected recording intervals may be viewed. If the channel is not set to be saved in the system memory, no history values will be displayed and “--.

The display will show some running digits when the temperature station is reset. Full segment will be displayed- user need to remove and re-insert batteries to restart the temperature station.
After batteries are re-inserted, the station will automatically launch the learn mode. The signal receipt indicator will be displayed. User needs to set again the temperature station for the desired application. (See ”SETTING UP” in previous clause) Note: If the battery level is low, the digits “No EPr” may be displayed on LCD after resetting, indicating that the power is too low for the temperature station to function normally. In this case, the batteries shall be replaced.
CHECKING FOR 433MHz RECEPTION If the outdoor temperature data is not being received within three minutes after setting up (or outdoor display show “- -. -” in the outdoor section of the Temperature Station after 3 failed attempts during normal operation), please check the following points: 1. The distance of the Temperature Station or transmitters should be at least 2 meters away from any interfering sources such as computer monitors or TV sets. 2.
POSITIONING THE TEMPERATURE STATION: The Temperature Station provides the option of table standing or wall mounting the unit. Before wall mounting, please check that the outdoor temperature(s) can be received from the desired location(s). To wall mount: 1. Fix a screw (not supplied) into the desired wall, leaving the head extended out by about 5mm. 2. away from the base and hang the station onto the screw. Remember to ensure that it locks into place before releasing.
The mounting surface can affect the transmission range. If e.g. the unit is attached to a piece of metal, it may either reduce or increase the transmitting range. For this reason, we recommend not placing the unit on any metal surfaces or in any position where a large metal or highly polished surface is in the immediate proximity (garage doors, double glazing etc.).
