12. Bottom heater control
In order to shorten the recovery time of humidity, conduct electricity to humidity heater as
follows.
In the ordinary, bottom heater should be conducted maximum 80% of electricity.
When the internal temperature is SV-0.4~-0.6deg, conduct 80% electricity to humidifying
heater for 10minutes or less. In a temperature except for above, SV in F06 is applied.
In the following time period, 80% electricity conduct should not be performed:
1) The period until an internal temperature reaches to SV-0.2deg after the power is
