Abstract
To guarantee a higher reliability of operation, the capacity of a battery to reliably open and close a water valve and to operate a microprocessor is continuously checked. To do so, a plurality of reference voltages are formed. The current voltage of the battery is compared with these reference voltages, and the state of the battery is indicated on the basis of this comparison with, e.g., an LED.
