To stop the manual additional
refrigerant charge operation (when
the required additional refrigerant
amount is charged), push BS3. If this

BS3, the unit will stop its operation
after 30 minutes. If 30 minutes was
not sufficient to add the needed
refrigerant amount, the function can
be reactivated by changing the field
setting again.
