In this mode, the DADS-01 has been designed to operate in automatic mode. Even if it is left locally in manual mode, the DADS-01 will revert to automatic mode after an 8-hour delay.
Note: The 8-hour timer is not factory activated for units destined to be operated via the USB port. Consult factory if this mode of operation does not satisfy your requirements or if your requirements have changed over time.
