Attention: With the webserver (EE242 Base Station), any time interval can be configured. Selecting a
time interval of less than 15 minutes for the transmitter, will greatly reduce the operating life of the batte-
ries. Typical operating life is up to 3 years, based on a transmission interval of 15 minutes (for T / %RH).
2. Push-button „CONNECT":
To establish the initial connection between the base station and the transmitter.
(For a detailed technical description, see chapter 4. "Starting up the Wireless System".)
Additionally the status of "signal strength level [%]" can be activated temporary with this key.
If you press the key for 1 sec while connecting the voltage supply (or the last battery is
inserted) the EE244 shows the "signal strength level [%] of the wirless connection for 60 sec before
switching back to the normal display mode.
3. Display:
Place the display on the designated pins.
Display symbols:

On the display all available measured values (RH, T, CO2) of the sensors (up to 3) are alternatly
indicated. Warning: The measured values are updated in the adjusted interval „TIME" (see chapter
