If the water temperature exceeds 35°C (95°F), the heater will automatically stop heating and display an "HH" error code. This protects your fish from high temperatures and prevents damage to the heater.
- Low Water Level Protection: If the water level drops too low, exposing the heating element, the heater will automatically shut off and display an "LL" error code. This prevents dry burning and protects the heater unit.
- Detecció d'errors: The temperature control system detects abnormalities. If an error is detected, an error code will be displayed, and heating will automatically stop to prevent potential damage or accidents. In case of an error, promptly address the issue.
- Font d'alimentació: Assegureu-vos que la font d'alimentació voltage matches the specifications of the heater (AC100-110V/50Hz).
