Operating instructions:

Preset at 78° F provided that the maximum difference between the ambient and preset temperature is less than 9.1° F.

It is necessary to monitor aquarium temperature on a regular basis with a reliable aquarium thermometer. If the set temperature is not reached due to various variables (lower environmental temperature, large temperature fluctuations, or aquarium next to colling sources), it will be important to increase the heating power.
