Overheating & Out of Water Protection
The hygger immersion heater automatically shuts off and stops heating when the water temperature exceeds 94 °F. An error code will be displayed, and an alarm will sound until the water temperature is below 94 °F. If the water in the tank drops below the minimum water level, the heater will automatically shut off and restart until fully submerged. Multiple heater protection protects the inhabitants of aquariums.
