If there is an extended delay at the 
process machine, it is easier to re-set a 
reduced drying temperature or shut the 
Process Heater “OFF” on the QuickOp 
screen but… this menu can be used to 
put or remove the dryer from second set 
point while unattended. When the 

system is enabled an  

icon will be 

displayed on the operations screens in 
the upper left corner.
