Review on 🔴 KNACRO 12V DC Relay Switch, Digital Time Delay Relay Board with Dual-color LED Display (Red+Red), On-Off Delay Timer Switch Supporting Time Cycles for Car Vehicle (Red+Red) by Kirt Phillips

I have a greenhouse and I wanted my water spray system to produce a 1 second burst every 90 seconds. I bought this device on 04/23/2020, I was able to program it and to date I am very satisfied with its performance (it works for 66 days). Now it's stuck in the "on" position. I unplugged it, plugged it back in, and when it was turned back on it stayed open again, resulting in my greenhouse being constantly foggy. I went to youtube and watched the video program your timer (how to program a KNACRO 1500W DC 5V relay switch) and set it up again for my needs. I had to install on my P1-4 and for some reason it defaulted to P1-1. I don't know why it did a "reset" and reverted to P1-1, but I can reprogram it as needed in the future.
