11.2 Pump Station Configuration

The NMC-Pro can include up to six pumps. Each valve (irrigation, cooling or misting) can be connected to one of the
pumps or to the pump station. The pump station is a group of pumps (out of the six possible pumps) that will be
started in accordance with the required flow.
The Pump Station configuration screen allows you to define which pumps are part of the station, the capacity of the
various pumps and their startup and shutdown delays.
The NMC-Pro automatically calculates the expected flow and determines which pump (or pumps) should be started
(see Valve Configuration for additional information regarding flow calculation). The NMC-Pro will start the minimal
number of pumps required to supply the calculated flow rate.
If several pumps should be started, the NMC-Pro starts from the largest to the smallest and will turn them off from the
smallest to the largest.
• Pump No.: Pump number.
• Capacity: Define pump capacity in m3 or gallon. This will be the maximum pump capacity, above which the
NMC-Pro will turn on another pump (if available).
• Stability (mm:ss): Define stability time. Stability time is the startup time required for current pump before next
pump can be started up. Stability time is usually used to prevent voltage drop down and water hammer (see
Pump Startup Order
• Off Delay (mm:ss) : Define off delay. Off delay will be the delay time for current pump to stop after last pump
has stopped. This delay is usually used to prevent water hammer (see
• Station (Yes/No): Define whether the pump is part of the pump station.
