Universal stop start K2579

Any help bit of a beginner had a couple of these kits all great stuff the new one bought this year trigger activated circuit led lights up clicks relay but will not turn off on the timer at all have to manual switch off

Well kit builders the problem I managed to solve it seemed to be the rheostat time adjuster had to move it back and forth short time long time and that clicked the off relay circuit for future users I have bought at least 4 of these kits and they work well in artwork pieces
