The segment ID and the device address constitute the controller’s entire address. The
address can be, for example, S0/G1 or S0/G2, which means segment 0’s (S0) master
(G1) and its first slave (G2).
The ACS program can only be connected to device address 1 (the master controller).
Any slave controllers connected to the bus will be displayed in the program through the
master controller. As usual, the program can be used to copy the settings across all
controllers connected to the bus through the master controller.
If you want to specifically connect to a slave controller using the ACS program, the
controller needs to be disconnected from the bus and its device address changed to "1"
via the controller’s user interface. If the value on line 5800 is set to
externally brine
,
the slave controller’s PI diagram will show any and all components that can be present
in the refrigerant circuit. Otherwise, the diagram will correspond to the actual controller
settings. If you want to check the slave controller’s wiring diagram for the refrigerant
circuit, temporarily set the value on line 5800 to
Brine circuit
.

6.3 Shared brine circuit pump
A shared brine circuit pump can be defined for the cascade. The shared pump will
always start when the first compressor in the running order starts, even if it is not
in the compressor circuit that is controlled by the particular controller. By default,
the cascade’s shared brine circuit pump is connected to the master controller in
accordance with the electrical drawings, and the slave controllers will request the
master controller to activate the output via the bus.
