D
120 min. (2 hr)
E
180 min. (3 hr)
F
240 min. (4 hr)
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
batteries. 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. Jumper „J1“ (EXT/BAT):
The allocation of the jumper allows for the selection of ‘battery power’ or ‘external power’.
4. Battery compartment:
Alkaline batteries, 4 off (1.5V, AA)
