Summary

  • Smart Heating System (SHS): Automatically adjusts heating power to maintain consistent temperatures, preventing fluctuations that can stress aquatic life.
  • High-Precision Thermostat: Offers accuracy within ± 0.5°C, allowing for precise temperature control between 20 and 33°C.
  • User-Friendly One Touch System: Easily set the desired temperature with a single button, and monitor both the programmed and current temperatures on the LED display.
  • Safety Features: Includes three sensors—two electronic and one thermal fuse—to protect against overheating and automatically shut off the heater in no-flow conditions.
  • Space-Saving Design: Mounted on the outlet hose of the external filter, it ensures even heat distribution and does not take up space inside the aquarium, allowing for more flexibility in tank arrangement.
