3.1.4 ECO mode 

In AC mode, the UPS can be set to work in ECO mode if the load has no strict 

requirement on the power purity and the UPS can stay in bypass mode normally. If 

the AC is beyond normal range, the UPS will transfer back to inverter mode.    The 

Efficiency for the UPS in ECO mode is much higher.
