Thanks, gents...although I must always keep in mind when @duanes talks about keeping fish at room temp...that he and I live in very different rooms! 
The link provided by @RD. included the very useful info that the species could do more merely survive a couple or three days of low temps, but rather seems well-suited to long-term health at those temps on a seasonal basis. Big difference.
If, like me, the OP is looking for a cool-tolerant cichlid, and depending upon what temperatures will be easily and safely provided, it sounds as though cyanoguttatus has a significant advantage over carpintis. In my neck of the woods, carpintis is by far more commonly seen for sale; must keep my eyes open...
