Universal RO Water Purifier Control Board with Mini Square Screen

Color LED Display, Built-In Sound Prompts, Fully Intelligent Flushing, Water Control, Automatic Fault Alarm, Short-Term Automatic Protection. Flushing: 18 seconds before each water production; 8 seconds every 2 hours during water production (pump operating, inlet valve open, flushing valve open, flushing light flashing). Water Production: When water supply is sufficient and the system detects a “not full” signal, it enters water production mode (pump operating, inlet valve open, flushing valve closed, water production light flashing). Water Full: System detects “full” signal and enters water full mode (pump stops, inlet valve closes, flushing valve closes, full water light remains on). Water Shortage: If low water signal is detected during flushing or water production, system enters water shortage mode (pump stops, inlet valve closes, flushing valve closes, low water light blinking). Maintenance: If continuous water production exceeds 6 hours, system enters maintenance mode and flushing valve closes. Recovery requires power cycle (pump operating, inlet valve open, flushing valve closed, flushing/water production/shortage indicators flashing). Application: Compatible with 400g and lower capacity RO water purifiers. Operating Voltage: DC 24V Inlet Water Pressure: Standard municipal tap water pressure Power Consumption: < 0.6W Operating Temperature: -20°C to +70°C Operating Humidity: 5%–85% Display Size: Approx. 71 × 30.2 mm Main Board Size: Approx. 130 × 61 mm Color: Blue Material: PCB Note: Designed for use with water purifier storage pumps, including models compatible with Water-128 (400g) type control panels.
