At the start of the firing the fan remains off while the kiln temperature is
below the fan start temperature. The fan starts when the kiln temperature
has risen to the fan start temperature and remains on until the kiln tem-
perature has risen to the fan stop temperature. The fan then turns off and
stays off until the end of the program.
The instrument will now reset and the new fan control temperatures will
be stored.
