Got a rooftop unit I'm trying to find diagrams on. It's a BDP model 581BEV0901B0AA5A. I had a no cooling call on it the other day and they have the economizer wired into 2nd stage. I think this is wierd. To me I think it sould be 1st stage. One better the smokes were wired in series with 2nd stage....lol. But thats fire security guys for ya.
There are 2 of these units on the roof and both diagrams are totally faded out. I called the local Carrier wholesaller and they said they didn't have anything on that model. I asked if the manufacturer would have it and he said if it isn't on there system then the manufacturer doesn't have it either.
The econimizer hood has 50DK00312B on it at the temp control.
