Full adjustment
After empty adjustment the full state is to be achieved, if possible, so that the unit switches.
The full adjustment can be repeated as often as you like. The stored value for the empty state is
not overwritten by the full adjustment. After a new empty adjustment both values are
automatically set again, the values last defined are overwritten. Therefore always carry out the
empty adjustment first, then, if necessary, the full adjustment!
Locking
The stored adjustment values can be protected against unauthorized programming as follows
(factory setting: not locked):
When the programming pushbutton is released the unit is locked and all programming functions
are inactive. The unit returns to the operating mode.
If this operation starts from the locked state, the green LED does not react for 10s. After 10s the
unit is unlocked (see "Unlocking").
