When entering energy savings, the unit is running at the energy savings bump frequency and when it is finished, it will
switch into the bypass run state.
Energy Savings Mode is active and the unit is running in Bypass Mode.
Energy Savings conditions are no longer present and the unit is leaving Energy Savings and returning to Drive Mode. The
exit conditions are when the frequency reference changes from the programmed Energy Savings frequency reference in Z1-
