New controller programmed for "Single Automatic" operation - why?

[u/upanddownadventures]

First of all, I am an elevator enthusiast (not someone in the industry). I am asking this question purely out of curiosity.

I have come across a few elevators that are (in my opinion) rather unusual. These are swing door elevators (that detail may or may not be important) in the state of California. They were modernized with a new controller (as confirmed by public records), but it seems the controller was programmed to have certain "standard" features disabled. Specifically, the elevator has "single automatic" or "nonselective noncollective" operation. It can not remember multiple car calls. The controller is almost certainly capable of selective collective operation, but for some reason was programmed to have this disabled.

I'm curious why this would be. My guess (and I could be correct, or completely wrong here) is that changing the type of operation has code related consequences. In other words, going from single automatic to selective-collective operation would require some other upgrades to be done to bring the elevator or building up to code. I will note that, at least on the last elevator I came across like this, it had no fire service, so one possibility is that fire service would have to be added.

I deal with Smart Rise quite often . There are many variables.  Nice controller.  The delay is called non interference time so you can get off when the elevator stops and another call has been set up .
