Electrical connection.
The two wired data bus cable must be connected
to A and B terminals .
The connection must be executed respecting the
polarity. The display does not show anything
whenever polarity is not respected. After con-
necting electrically the zone manager, refit the
front cover till the clamping.
BUS address setting.
The connection between zones managers and
cascade regulator must be obtained through a
data bus cable with two wires. Since the zone
managers are connected in parallel to the data
bus cable, the data transmission requires a bus
address.
BUS address (zone manager).
The bus address classification between cascade
regulators and zone managers is defined by a
rigid scheme set by the producer as explained
in the following scheme:
