3.6.1 Cluster address configuration
When setting up the valve cluster solution, each valve needs a unique cluster address.
This address must be configured on each valve prior to operation via the service port by using the graphical interface
(SETUP –> CLUSTER) or the Terminal function of the Control View software or Control Performance Analyzer software.
The used addresses must be in a consecutive order.
Further the Master valve needs the information about the total number of valves (including itself) connected to the valve
cluster.
Note: Prior to sending the address command, set the valve to LOCAL operation.
