Bus address (Cascade manager).
If there is only one regulating unit, it is always assigned bus
address 10. When there are multiple connected regulating
units (maximum of 8), the regulator that is connected di-
rectly to the boiler must be assigned address 10. The other
regulators must be assigned addresses with progressive
numbers, such as 20, 30, 40 and 50.
