System repeats APC behavior every cPr time.
In a power outage, cooling cycle time cPr is not
reset, It will continue from last recorded time.
Example:
if there is an 1 hour power cut, the next
cooling time will delay about 1 hour.
Remaining time to next cooling can be checked by
the controller
( see page 9)
