Time delay range: T1 and T2 between 0.1 seconds to 99 hours adjustable.

P1 (Delay turn off): when power on, the relay on, delay T1, and then the relay off. Default setting.
Give IN a low level, repeat the above function.

P2 (Delay turn on): when power on, the relay disconnected, delay T1, and the relay on.
Give IN a low level, repeat the above function.

P3 (Timing cycle on-off): when power on, the relay on, delay T1, and the relay off, delay T2, the relay on, and then repeat the above condition. Cycle times can be adjusted 1-99 times or infinite loop.

P4 (Timing cycle off-on): when power on, the relay disconnected, delay T1, and the relay on, delay T2, the relay off, and then repeat the above condition. Cycle times can be adjusted 1-99 times or infinite loop.

P5 (Trigger delay turn off): when power on, the relay disconnected, triggered the relay on, delay T1, and the relay off. Give IN a low level, repeat the above function.

P6 (Trigger delay turn on): when power on, the relay disconnected, triggered the relay disconnected, delay T1, and the relay on.
Give IN a low level, repeat the above function.

P7 (Trigger cycle on-off): when power on, the relay disconnected, triggered the relay on, delay T1, and the relay off, delay T2, and the relay on, and then repeat the above condition. Cycle times can be adjusted 1-99 times or infinite loop.

P8 (Trigger cycle off-on): when power on, the relay disconnected, triggered the relay disconnected, delay T1, and the relay on, delay T2, and the relay off, and then repeat the above condition,. Cycle times can be adjusted 1-99 times or infinite loop.
