Nano supports Child-Lock to prevent children from hot water burns. In standard mode, the Child-Lock feature is OFF. You can activate this feature in the App.
When Child-Lock is activated, each time you want to dispense hot water, tap and hold the HOT button, then tap the ROOM button once to unlock the Child-Lock. After the water starts to flow, you can also use the Volume Slider.
How to activate
Go to Device -> Setting
Turn on the Child-Lock feature
