- Unitat de control principal: Houses the electronics, power outlets (DRAIN and FILL), LED display, and control buttons (MUTE, MANUAL, FILL, DRAIN, AUTO).
- HI Sensor: High water level sensor.
- LO Sensor: Sensor de nivell d'aigua baix.
- Cables d'alimentació: For connecting the unit to a power source and pumps to the unit.
4. Configuració i instal·lació
The Ortis Automatic Water Level Controller is designed for easy installation without plumbing modifications. All necessary installation tools are included.
4.1 Muntatge de la unitat de control
- Choose a dry, accessible location near your aquarium, tank, or pool.
- Use the provided screws and wall anchors to mount the control unit securely to a wall or cabinet. Alternatively, use the included adhesive pads for temporary or non-permanent mounting.

4.2 Col·locació del sensor
The HI and LO sensors detect water levels. Their placement determines the operating range for filling and draining. The sensors are adjustable from 1/4 inch to 20 inches.
- Attach the HI and LO sensors to the inside wall of your aquarium or tank using the provided suction cups.
- Position the LO sensor at the desired minimum water level. When the water drops below this sensor, the FILL pump will activate (in appropriate modes).
- Position the HI sensor at the desired maximum water level. When the water reaches this sensor, the FILL pump will deactivate, and the DRAIN pump will activate (in appropriate modes).
- Ensure the sensors are securely attached and their cables are routed safely to the control unit.

4.3 Connecting Pumps
- Connect your refill pump to the "FILL" outlet on the control unit.
- Connect your drain pump to the "DRAIN" outlet on the control unit.
- Ensure pumps are compatible with the controller's maximum capacity (Max 2Hp, 16A).
5. Instruccions de funcionament
The controller offers four operating modes: Automatic Water Change, Fill, Drain, and Manual.
5.1 Selecció del mode
Use the buttons on the control unit to select the desired mode:
- AUTOMÀTIC: Activates the automatic water change function.
- Omplir: Activates the automatic water refilling function.
- DRENAR: Activates the automatic water draining function.
- MANUAL: Allows manual control of the connected pumps.
5.2 Automatic Water Change Mode
In AUTO mode, the controller manages both draining and refilling to perform a water change. The system will drain water until the LO sensor is exposed, then refill until the HI sensor is reached.
- Premeu el botó AUTO button to initiate an automatic water change cycle.
- The DRAIN pump will activate until the water level drops below the LO sensor.
- Once the LO sensor is clear, the FILL pump will activate until the water level reaches the HI sensor.
- The cycle completes when the HI sensor is covered.

Figure 5.1: Illustration of the automatic water change process using the AUTO mode, showing the controller connected to both drain and fill pumps.
5.3 Fill Mode
In FILL mode, the controller maintains the water level by activating the refill pump when the water drops below the LO sensor and deactivating it when the water reaches the HI sensor.
- Premeu el botó Omplir botó.
- The FILL pump will activate if the water level is below the LO sensor.
- The FILL pump will deactivate when the water level reaches the HI sensor.

Figure 5.2: Illustration of the fill operation. The pump turns on when water is below the LO sensor and turns off when it reaches the HI sensor.
5.4 Drain Mode
In DRAIN mode, the controller activates the drain pump when the water level reaches the HI sensor and deactivates it when the water drops below the LO sensor. This mode is also suitable for sump pump applications.
- Premeu el botó DRENAR botó.
- The DRAIN pump will activate if the water level is above the HI sensor.
- The DRAIN pump will deactivate when the water level drops below the LO sensor.

Figure 5.3: Illustration of the drain operation in a sump pit. The pump turns on when water reaches the HI sensor and turns off when it drops below the LO sensor.
5.5 Manual Control Mode
The MANUAL mode allows you to manually activate or deactivate the connected pumps.
- Premeu el botó MANUAL botó.
- Further presses of the FILL or DRAIN buttons will toggle the respective pumps on or off, overriding sensor input.
- Return to an automatic mode (AUTO, FILL, DRAIN) to resume sensor-based operation.
5.6 Funció d'alarma i silenci
The controller includes a built-in alarm to notify you of potential issues such as pump failure or blockage. The LED display provides clear indications.
- If an alarm sounds, check the connected pumps and plumbing for any obstructions or malfunctions.
- Premeu el botó MUT button to silence the alarm temporarily if needed.
6. Manteniment
- The HI-LO dual sensors are constructed from 304 stainless steel, designed to be resistant to corrosion and not affected by minerals or water debris. They generally do not require cleaning.
- Periodically inspect all cables and connections for wear or damage.
- Ensure the control unit remains dry and free from dust.
