8. Optionally, change
Format
to the desired number
of temperature decimal places.
9. Optionally, change the
Average
to the desired
number of thermistor readings averaged before
displaying the result.
If the Override Input is
being used,
Average
may need to be reduced
down toward 1 to ensure reliable recognition of
the button press, depending on the controller.
NOTE: The Up and Down buttons need to be
held down for at least a half a second to be
reliably recognized for override mode.
