I'm hoping someone out there has an old Otis DC reostatic controller print out there. It's a 1-LC-0 controller the sales number is NU-752-1. I'm having a problem with the door reopening as soon as the door open limit makes up. the problem seems to be coming from the HO relay.

Sorry, I don't ever remember coming across a 1-LC-0 controller. Any chance you could post a picture?
I do remember some of the old UCL controllers having an HO. It was used as a home landing switch.
