Oase ProfiClear Guard Level Control

Oase ProfiClear Guard Level Control – Automatic Pond Top-Up System

Maintains constant water level | Complete ready-to-install set | Ideal for ponds and reservoirs

The Oase ProfiClear Guard Level Control is a complete automatic pond top-up system designed to maintain a consistent water level in ponds and reservoirs. Simple to install and low maintenance, the system automatically refills your pond when the water level drops, ensuring stable operating conditions for filtration systems and aquatic life.

This complete set includes a plug-in transformer, controller unit, conductive sensor probe, and 1" BSP male solenoid valve. The transformer converts the 240v mains supply to a safe low voltage for the controller and sensor operation. An LED status display on the controller keeps you informed of the solenoid valve’s operating state at all times.

The conductive probe is installed at the desired water level and features clearly defined MIN (REF) and MAX sensors. When the water level drops below the longer MIN and REF probes, the valve opens to allow refill water into the pond. Once the water reaches the shorter MAX probe, the valve automatically closes. A 20mm switching differential (gap between MIN and MAX probes) prevents rapid cycling, while integrated hysteresis reduces unwanted refilling caused by waves.

The sensor can be shortened to achieve a reduced switching differential down to 10mm if required. A mounting bracket for overhanging pond edges is included for flexible installation.

Important: When connecting to a mains water supply, an appropriate air gap must always be maintained to prevent backflow contamination.
