Water, electricity, or heat is supplied according to credit balances, budgets, and tariffs. Credit, volume, and time-based tariffs can be selected. Budgets can be provided automatically on an annual, monthly, or daily basis.
If the credit is used up, the supply can be interrupted immediately or after a warning and surpassing a credit line. The interruption can also be triggered remotely and manually by the administration.
