Air Defrost
Many applications of the KE2 Temp + Air Defrost can use the
controller’s preset defrosts per day. This automatically spaces the
defrosts throughout the day, based on the number of defrost cycles
selected. The user has the ability to change the number of defrost
cycles performed by changing the Defrost per Day setpoint from 0
to 12.
For more specic applications, the KE2 Temp has the option to
schedule each individual defrost at a specic time of day.
