11. Bottom heater control
In order to shorten the recovery time of humidity, conduct electricity to humidity heater as
follows.
In the ordinary, the maximum electricity conduct to bottom heater should be in the ratio of
80%.
When the internal temperature is SV-0.4~-0.6deg, conduct 80% electricity to humidify
heater for 10minutes (max). SV in F06 is applied except for above temperature.
80% electricity conduct should not be performed in the following cases:
1) The period until an internal temperature reaches to SV-0.2deg after the power is
supplied
2) The period until an internal temperature reaches to SV-0.2deg after the door is left
opened continuously for 60seconds or more.
12. Door heater control
Ordinarily, conduct electricity to door heater in the same ratio with main heater. SV in F07 is
applied.
13. Remote alarm: remote alarm contact
In normal condition ......... Open
In alarming condition ...... Close
Note) The recovery time after BZ key is pressed and linkage between remote alarm and buzzer
are depending on F24, F25 setting.
14. Storing in non-volatile memory
2 times comparison method: When the main power is supplied, a data storing in non-volatile
memory is called for 2 times to compare. If the data 1
called, the data would be stored in RAM. Otherwise, the comparison would be repeated until
the one coincides with another.
15. Temperature offset value
The difference between temperature sensed in temperature control sensor and temperature in
internal 1/2H should be offset:
Offset value: +0.8 C
16. Example for displays
Current temperature +36.2 C
Set temperature +37.0 C
