If you are setting the timer and you are currently outside of the timer you wish to have, you will need to switch the unit to the OFF state by a 2 second press on the power button and let go. Conversely if you are adjusting it so the current time is inside the timer window, you may need to switch the unit to the ON state by a 2 second press on the power button and let go.
If you have shortened the timer but not switched it to the OFF state then the unit could reheat based on water usage until the next time the timer window turns ON and then OFF.
If you have lengthened the timer but the unit is still OFF then you will need to switch the unit to the ON state otherwise no heating will occur until the next time the timer window turns ON and then OFF.
When the timer ON time is reached it activates the display and will show the temperatures etc, at the end of the timer window the display will return to the OFF state.
