The HMS heater series 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 HMS heaters to have precise control, keeping the
water temperature stable while avoiding wide temperature swings common with low-quality
aquarium heaters. The controller displays the current temperature, allowing you to easily
make temperature adjustments on the front panel. Temperature can be adjusted by a tenth
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. The heater is constructed of corrosion-resistant titanium, making it safe for freshwater
and marine aquariums. The heater tube is virtually unbreakable and features a protective
heater guard to prevent aquatic live from accidentally coming in contact with the heating
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 mainte-
nance and care.
