NOTE: When the temperature is set to a lower temperature than in the previous stage,
the furnace ignores the programmed HEAT RATE (except for "NO") and
automatically cools to the pre-set temperature. The time required for the cooling
stage is determined by the pre-set temperature. The lower the temperature,
the more time needed to cool down.
