Packed with the most advanced features in residential control, the modular design of the Pro-C offers the flexibility to change the number of station outputs (from 3 to 15) at any time. That way, upgrades can be made to a landscape without having to change out the controller. From a contractor’s standpoint, this also means that only the controller and modules need to be stocked, so maintaining inventory is simple and easy. Modularity isn’t all this controller has to offer. It is also compatible with Hunter’s Solar Sync ET sensor. With the revolutionary Solar Sync sensor, the Pro-C is converted into a “smart controller”, which regulates irrigation runtimes based on locally measured weather. Pro-C is also compatible with Hunter remotes for quick, wireless irrigation activation.
