Hilitand YYB-5 12v 24v Forward/Reverse Motor Control Board Two Relay Timing Cycle Module

Does it lose its programming if power is disrupted to the module?

Can I wire external buttons?

For p-1, if the signal remains on gnd after the relay stops, does it automatically re-trigger, or does it need to go off gnd and back on to re-trigger

how do you wire a PIR sensor to make it start the program?
