 FACT: In the tanning bed room, when the temperature controllers  display changes from 77 to 78¡F, it can be seen that the fan control  switch on the lower left side is set to "On". This should normally  have the fan (the one built into the wall, not in the tanning beds)  running all the time. However, it is then shown how it turns on due  to increased temperature in the room and makes the coat hanger  wobble. The switch should be set to "Auto" if this were to happen.
