No change at all it does not reset the display does not blink it carries on as normal other that that relay clicking on. I just don't get it I've moved wires to make sure they are not picking up noise from he mains etc I'm stumped I've now rebuilt this 3 times same outcome every time i have even moved the pin from 9 to 8 to make sure it's not the channel. I do however seem to be getting 4.6v at the relay signal terminal but I'm unsure how sensitive the transistor is on the relay board and whether that is to low of a voltage triggering the relay.
