Complete Guide to the ROC-2015 Reverse Osmosis Controller The ROC-2015 is a specialized microcomputer-based controller designed for the automatic management of small-scale, single-stage reverse osmosis (RO) water purification systems. By integrating sensor inputs and control outputs, it automates essential processes such as pump operation, valve switching, and membrane flushing. 1. Key Technical Specifications
Understanding the hardware limits is critical for a safe and effective installation. Power Supply: AC 220V ±plus or minus 10%, 50/60Hz. Power Consumption: ≤is less than or equal to Output Contact Capacity: 5A / 250V AC (resistive load). Environmental Limits: Temperature 0–50°C; Humidity ≤is less than or equal to Physical Dimensions: 48 x 96 x 80 mm (H x W x D). Panel Cut-out Size: 44 x 92 mm. 2. Core Functions & Operational Logic
The ROC-2015 automates the water production cycle through several protective and maintenance modes:
Low-Feed Protection: If inlet pressure is too low or the raw water tank is empty, the controller pauses the system and triggers an "ALA" alarm.
High-Pressure Protection: To prevent hardware damage from overpressure, the system shuts down and attempts up to three trial startups after pressure stabilizes.
Tank Level Management: It automatically starts water production when the pure water tank hits a preset "low" level and stops once it reaches the "high" level. roc-2015 controller manual pdf
Automatic Membrane Flushing: The unit initiates a flush cycle upon startup and after filling the product tank to maintain membrane longevity. 3. Wiring and Terminal Connections
All control ports use dry contact relays sharing a common (COM) terminal.

If you are working in Northern Alberta in January, check the "Ambient Temperature Limits" section—it explains why the screen goes blank until the internal heater (if installed) kicks in.

Solution per manual: Review the low-temperature specifications in Appendix A. If the unit drops below -30°C without a heated enclosure, the LCD display may freeze, and the power supply will enter brownout protection. The manual recommends a thermostatically controlled heater for arctic installations.
