Basically how it works is like this; the bit as a small lump of metal of
the end that fits into the iron This metal has a well defined Curie point
temperature.
The sensor has a magnet that slides in the tube against a spring. When
the bit is below the curie point the magnet is attracted towards the bit
and closes the switch to the element. When the bit goes over the curie
point the magnetic attraction falls and the spring pushes the magnet away
and opens the switch.
So to change the tip temperature you need to select a bit with a different
curie temperature. The bits have the temperature marked on the end in
degrees F, 6 = 600F 7=700F etc.

Well! You learn something every day.

TA!
