Why is there a "always ventilated" indication on the toilet fan switch? Updated date 2019.10.22

Some buildings have a "24-hour ventilation system" in which outside air flows in through the ventilation opening on the balcony side (entrance side) and the outside air flows out using the ventilation fan of the toilet.

In apartments, it may be obliged to install ventilation equipment such as "●% of room air is replaced per hour". "24 hour ventilation system" is installed based on those standards.

If you turn off the toilet ventilation switch, the 24-hour ventilation system will not work. Please use it with "always ventilated" during your stay.
