*The timer includes a small optional capacitor that can be used to shield it from external EMI/inductive noise. While not an issue with our control panel designs and parts, users who choose to build something different may notice the timer rebooting when mechanical relays inside the panel turn on and off. Install the capacitor across the timer's relay outputs to resolve the issue. If wiring the timer per our design with an alarm light and buzzer, this would be the normally open (NO) terminals 7 and 8 (as shown in the last picture).
