How do you adjust the defrost cycle on a K202SDF, K204SDF or K210SDF

Adjust when the defrost cycle spikes the temperature or does not defrost the unit properly.

Elitech ECS 160 - Defrost Cycle Adjustment - Advanced Programming* 

How do I know if my controller is an Elitech? If your controller has 4 control buttons on the right side of the screen, you have an Elitech controller. K2 Scientific changed from Elitech controllers to Dixell controllers in 2019 and 2020.  If you purchased after 2020, your unit most likely has a Dixell controller. 

* The K2 Technical Service Team only recommends making this adjustment after consulting with a K2 service team member.  A consultation ensures no other issues or parameter adjustments are needed to continue safe, energy-efficient operation.  A consultation before adjustment is mandatory if your unit is under warranty.
