Used to calibrate the valve at Zero OD %. When the user set the manual homing, a full closing operation will be
performed (same as initial closing). After the operation is performed the manual homing parameter [B104 - Manual
Homing] will be set back to off and the parameter for [O045 Manual OD] will be set to 0%. When manual mode
becomes inactive the actual OD will be the starting point for automatic control
