This heater has an automatic system, so the button only works to turn the product on, but not to turn it off.

It has a thermostat which is activated when the water is finished evaporating, so it is important to only place the water mentioned in the instructions.

The water should be allowed to evaporate and allowed to continue working, for a short time.

The product will turn off automatically and the button will be released to be able to activate it later.
