Here you will learn how to configure the COM1 (local) and COM2 (remote) ports. The manual details the difference between ROC Plus Protocol (proprietary) and Modbus RTU (open standard). It includes the memory mapping for Modbus addresses—critical if you are polling data into a third-party SCADA.
The controller triggers a high-pressure flush valve during startup, shutdown, and at preset intervals to prevent membrane fouling.
If you're able to find the manual, it should cover a range of topics including:

ROC-2015 Controller: The Ultimate Guide and Operation Manual
To prevent hardware damage from overpressure, the system shuts down and attempts up to three trial startups after pressure stabilizes.
Carrying a 300-page paper manual is impractical. Here is how to leverage the digital format:
Once all connections are securely fastened and verified, turn on the power. 4. Operational Modes and Indicators
If your system fails to operate as expected, check these common indicators: Potential Cause Faulty connection or fuse Check AC 220V supply and terminal block fuses. System Won't Start Activated protection

Protects the pump when input water pressure is too low.
Check the battery voltage annually via the software diagnostics tab.
In a typical cycle, the ROC-2015 manages the transition from raw water to purified storage:
