RFID functionality
RFID stands for Radio Frequency Identification.
There is a microchip with an antenna under the decal
on the system care bottle, also called a tag.
The write/read electronics inside the appliance can
read data from the tag and also write data to the tag.
The power supply is sent to the tag from the radio fre-
quency field.
The write/read electronics query the type of detergent
and saves the dosed units to the tag. When the bottle
is depleted after 3,000 units or when the level switch
in the system care container announces depletion, a
trailing time of 5 hours is started. This trailing time is
counted on the tag. Once the trailing time has
elapsed or if the empty bottle is removed, the heating
operation 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 system
care bottle.
