6.10.3 Functionality RFID

RFID (Radio Frequency Identification) stands for the iden-
tification by means of high frequency.
There is a transponder under the label on the softener bot-
tle (microchip with antenna, also called tag).
The write-read electronics installed in the RFID attachment
can read data from the tag and also write data to the tag.
The tag obtains the power supply from the high frequency
field of the write-read electronics. The data transfer takes
place by changes of the field intensity.
The write/read electronics query the type of detergent and
saves the dosed units to the tag.
When the bottle is empty (after 2000 units) or when the lev-
el switch in the softener container reports empty, an after-
running time of 5 hours is started. This after-running time
is counted on the tag.
When the after-running time has elapsed or if the empty
bottle is removed, the burner is switched off.
Once a bottle has been detected to be empty, it is blocked
electronically and can no longer be used. Therefore, you
must insert a new original softener bottle.
