Bought this on Aliexpress to manage centralised heating\cooling. No documentation on the Air Dampers so I thought I would save someone some time.
Got a 12V
Color mappings;
Opening\Closing duct
Red- Common (GND)
Green - Close duct (VCC)
Black - Open duct (VCC)
Duct sensor
Grey - Common
Yellow - Duct open 0ohm (Grey-Yellow)
White - Duct closed 0ohm (Grey-White)
With this one you can actually detect when the duct has closed or not, and that way you destroy your aircon.
