3.4 Intended use
The product can be used to pump:
Cold water
Hot water
Refer to the standard Installation, Operation and Maintenance Manual for pump design
specification.
The variable speed pump units are made for the following applications:
Pressure, level, and flow regulation (open loop systems)
Single or multi pump irrigation systems.
3.4.1 Application alternatives
Actuator (constant speed)
The unit operates as an actuator according to speed set point; this is done through user
interface, the corresponding analog input or the communication bus.
Controller (constant pressure)
This mode is set as the default operating mode, and is used for single pump operating units.
Cascade serial / Cascade synchronous
The units are connected via the RS485 interface and communicate via the provided protocol.
The combination of the different units which are used in a multi-pump system depends on the
system requirements.
It is possible to run all pumps in cascade serial mode and cascade synchronous mode as well. If
one unit fails, then each pump of the system can become the lead pump and can take control.
3.5 Improper use
The product must not be used for closed loop systems.
