The temperature is equal to the starting temperature. Set the " ▲" heating button or the "▼"
cooling button to adjust to the appropriate temperature.
[Example] The shutdown temperature is set to 24 degrees and the temperature difference is set

It is a 24-degree shutdown and a 26-degree start.
When the “▲” key is pressed, the F2 code (temperature correction function) is set to “0” by
default. If there is an error between the display temperature and the actual water temperature,
first confirm the error value.
[Example] 1. The water temperature of the fish tank is 25 degrees, and the display shows that the
temperature is 23.5 degrees.
Actual error: 25-23.5=1.5
Operation method: Enter code F3, press -Set button, then press " ▲ " button, adjust to 1.5
