a FLOW MAX System
Flow Max is a unique feature specifically designed to manage multiple DXi controllers
which share a common water source. Flow Max systems intelligently share resources
and manage operations for satellites utilizing a single point of connection (POC). The
shared resources may include up to two common pumps, up to three Flow Meters,
and up to three Master Valves.
Figure D-1: Flow Max Hardwire Configuration illustrates a typical installation.
The Flow Max feature is not applicable for controllers which have exclusive
use of its water source (as in, one point of connection (POC) per controller).
Please refer to Appendix B: Flow Meters whenever flow and flow control is
required for a single controller installation.
Flow Max utilizes the intelligence of DXi field satellite controllers to provide the
following features:
• Operation of shared Master Valves, Pump or Flow Meters across controllers
without the need for peripheral relays or complex wiring.
• Shared devices may be wired in the conventional fashion to the nearest
controller.
• Dynamic adjustment/validation of station flow limits as stations turn on and
off anywhere in the system.
• Detection of system main line breaks.
• Detection of system unscheduled flow.
• Ability to read the flow GPM rates at any of the Flow Max participant
