Finnex HC-820M Digital Heater Controller +Sensor
The HC-820M Finnex heater controller uses an advanced digital processor that monitors and controls the water temperature in your aquarium. The heating controller receives temperature data from the remote sensor in the aquarium. The remote sensor contains no bi-metallic contacts to arc, corrode or wear out. This allows the HC-820M to have precise control, keeping the water temperature stable while avoiding wide temperature swings common with low-quality aquarium controllers. The controller displays the current temperature, allowing you to easily make temperature adjustments on the front panel. Temperature can be adjusted by 1/10th of a degree

The remote sensor also functions as an automatic power cut-off switch. If the water level drops too low and exposes the temperature sensor to the air, power to the heater tube is turned off. This prevents over-heating of the aquarium, saving your prized aquarium life from harm or other hazards. Maintenance: Secure the out-of-water sensor directly beneath the sensor cord clip, without any cord slack, and above the heating element at all times. Clean and confirm the out-of-water sensor is functioning properly every 30 days. Do not use heater if the out-of-water sensor is inoperative. Refer to the instruction manual for proper maintenance and care
