The NFS-2 controller from TrolMaster is one of the most advanced irrigation controllers available today. The NFS-2 is a multi-functional controller which can control multiple irrigation solenoids and pumps. The NFS-2 can also monitor multiple water sensors that can measure pH, EC / PPM, temperature and water content sensor. There is also a new optional DFW-1 flow-meter that serves multiple functions. Each of the solenoids and pumps can be "linked" to work together so that multiple grow areas can be controlled by a single NFS-2. When combined with the optional AMP-3, WCS-1 and WCS-2 sensors and the new DFW-1 flow-meter, the NFS-2 allows the user to monitor up to 50 sensors and receive mobile notifications if a problem is detected by the system.

The NFS-2 was created to allow users to customize their irrigation cycle and be able to control the irrigation events by using either the DFM-1 digital flow-meter, WCS-1 or WCS-2 moisture content sensors or by simple timers. Each device being controlled by the NFS-2 can conceivably have an unlimited number of irrigation "events" each 24 hour day.
