Bus address (Cascade regulator).
In case that only one cascade regulator is in-
stalled, the bus address is always 10. With more
regulators connected (at least five) the regulator
directly connected to the boiler must have the bus
address 10. For the other regulators, the addresses
must follow numbers 20, 30, 40 e 50.
