Duplex control wiring
The controller can be configured to operate in a duplex control system having 2
controllers and 2 variable speed pumps. In this configuration pumps can be staged and
destaged as needed and the lead pump can be alternated. When both pumps are on they
operate at the same frequency. To configure the controller for this type of system, a
specific wiring configuration is required. The diagram below shows the wiring required to
implement the duplex control system.
