If TDS readings seem inaccurate, clean the sensor probe with mild detergent.
Detects low water level in the source tank or low pipeline pressure. Security Filter Protection
It is highly probable that the model number is either a misinterpretation of a similar model name (such as the by Emerson), a reference to a specific year (2015), or a typo for a different controller series (e.g., RKC , REX , or LOVATO ). roc-2015 controller manual pdf
Main AC power input (ensure voltage matches your specific unit label). GND: Ground terminal for electrical safety.
Drives the raw water input solenoid valve. If TDS readings seem inaccurate, clean the sensor
Proper execution of the electrical terminal layout prevents back-EMF feedback and protects internal microchips from voltage surges. The terminal layout is divided into digital sensor inputs (low voltage) and relay control outputs (high voltage).

The controller uses five digital input (DI) ports and four output control ports to manage the RO system. Terminal ID Description Terminal Function Main Power Connect to 220V AC grid power. COM Common Point Common port for acquisition terminals or control relays. IV Inlet Valve Output contact for the water feeding solenoid valve. FV Flush Valve Output contact for the RO flushing solenoid valve. HP High Pressure
