dei 530t controls 4 motors in 1 direction

From reading some posts, I am under the impression that one 530T can control 4 motors in one direction with one aux channel. How can that be done or is that wrong info? Thanks.

I'm trying to think this through, but you might have to modify the circuit board to make the four relays power one way at the same time.

The 530T is not designed to do 4 windows. it is designed to do 2 windows both directions. as howie said the circuit board would have to be altered to perform this function. If the unit is damaged because of this work, its not covered under warranty and you'll be buying a new one. might as well save yourself time and money and get 2 of them and do it properly and all warranties are good.
