◆ Energy saving advice ◆
Eco operation setting
Eco operation stops the preheat or precool operation during the final cycle.
When Eco Run is set to [ON] in the detailed conditions of the pattern settings,
the chamber is operated in a manner that decreases power consumption by
not performing an unnecessary preheat or precool operation during the final
cycle.
When starting high
temperature exposure
When starting low
temperature exposure
The high temperature exposure preheat operation is not
performed after the final cycle of high temperature exposure.
The low temperature exposure precool operation is not
performed after the final cycle of low temperature exposure.
If eco operation is on, the
preheat operation is turned
off.
