10.2.6 Energy Saving Mode
In order to enhance the lifetime of a system and reduce the energy consumption
the energy saving modes (ESM) were implemented. For example, protection of the
pump against overheating if the load valve is closed and no fluid is being pumped.
Should the inverter be required to restart having been powered off and on in
Energy Saving Mode, it is necessary to activate the Auto-restart function of the
inverter (using P1210=6).
NOTES
Energy Saving Mode only operates in a positive direction.
Energy Saving Setpoint must be greater than fmin.
