I have a Leviton light switch (picture). It automatically turns off after about 15 mins of absence of motion and will turn on if I enter the room only a few minutes after it has turned off.
However, if a long enough period elapses it won't automatically turn on and I have to press the button again.
Is there a setting to change so it automatically turns on by itself at any time?
Update: on the inner metal plate it says: "Cat. No. IPV15"
