[@srieminenttechsolution]

Hello, I have recently installed a VTS wing air curtain system at my office premises but I couldn't understand how to install the door sensor to operate the blower when door is opened. Could you please help ? The model I've installed is 150 w/e/c with wall Controller WING/VALCANO. So I don't see any provision to install the door sensors where it's available in EC model. Plz inform how I can install the automatic door sensor/any other alternative solution to operate my blower.
