Energy Status Messages
While the compressor has power (started or stopped), an energy status screen can be
displayed by the controller. The energy status display can be selected by the operator
by pressing the energy status button. The operator can return the display to the current
status by pressing the status button. The following items and their present values will
be displayed on the right side (area 2) of the screen by pressing the UP and DOWN
arrows.

package kW per hour, removing the blower power usage, and then dividing that number
by the motor kW per hour for that size of compressor at 100% capacity.
