Why does the Oceanic Heater temperature window display '--Lo' or '--Ho'?
- TThomas KimAug 3, 2025
The temperature window on your Oceanic Heater might display '--Lo' or '--Ho' due to several reasons: * If it displays '--Lo,' it could mean the temperature sensor isn't connected, the cable is broken, or the temperature is below 0°C. Check the connection and cable, or consider changing the sensor. * If it displays '--Ho,' it indicates a short circuit in the temperature sensor or that the temperature exceeds 115°C. Inspect the connection and cable, or replace the sensor. In some cases, you might need to change the controller.
