Подключение клапана с возвратной пружиной ОЗК к модулю управления МДУ-1-R3 (версия 2 полная)

When installing valves and control units (no matter the manufacturer), I often forget (or don't know) how to properly connect the valve. I made a video to give myself a hint, trying to explain the operating principle and logic for those who don't know the ropes. Always check the limit switches with a tester before installation—it's the most reliable! In this case, the purple and white switches are open, and the yellow and green switches are closed. In the first video, I was too lazy to do this and had to reconnect the valves later. Setting up the valves in Firesec is in the next video.
