For example: When the water temperature in the aquarium is 20° C and you want to heat it up to
25° C, operate as follows: Hold the “Set” key for 5 seconds to enter into the “Setting” mode. The
“Set” LED starts flashing. Press the “+” or “-“key to adjust the set temperature to 25° C.
The compressor and the fan will start working after 15 seconds and the “Set” LED lights will be on
instead of flashing (standby state). The machine will start heating. When the water temperature
rises to 25° C, compressor and fan stop working. The “On” LED lights will be off and the machine
stops heating.
