Programming the Controller
Many applications of the KE2 Temp + Air Defrost can use the control-
ler’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 per-
formed by changing the Defrost per Day setpoint from 0 to 12.
For more specific applications, the KE2 Temp has the option to sched-
ule each individual defrost at a specific time of day.
