I have a building that has multiple override sensors whose only purpose is to bring on the ac when it is pressed after hours. It is connected to a 6400 controller and the ac's are carrier box cars.
The problem is they don't work.
Can someone tell me how they are supposed to be wired and how they communicate via the 6400 under what algos etc?
I know that their purpose is to short out when pressed but thats pretty much all I know.
