Under what circumstances can it lead to a decrease in temperature in the side-line product collection tank and an increase in temperature at the top of the tower?

There is a side-stream distillation column, with the side-stream outlet located above the feed tray. With both the reflux flow and steam volume remaining constant, under what circumstances will this lead to a decrease in temperature in the side-stream product collection tank and an increase in temperature at the top of the tower?
Feed rate and composition, bottom temperature, reflux rate.
