Programming Mode 

Note: The programming mode gives access to several functions that are 
not  intended  for  user  adjustment.  The  procedures  below  provide 
direction to the functions that you can adjust. Please do not attempt to 
change any of the other functions in the programming area or your unit 
may be damaged or become unstable.

To  lock  the  control  keys,  simultaneously  press  and  hold  the  up  arrow  and  the  down 
arrow. The display will show “POF”.  At this point you can only use keys to view the SET 
temp and the minimum and maximum stored temperatures.  
 
To unlock the control keys, simultaneously press and hold the up arrow and the down 
arrow.  The  display  will  show  “Pon”.  The  control  keys  are  now  unlocked  and  you  can

Adjusting the temperature control set points: 

NOTE:  The  temperature  control  set  points  are  preset  at  the  factory  to 
provide the desired air and product temperatures inside of the unit and 
require  no  further  adjustment.  Please  contact  the  manufacturer’s 
Technical  Service  Department  before  making  any  adjustments  to 
determine  if  adjustment  is  necessary  and,  if  so,  to  make  sure  it  is 
performed properly.
