Good question. Planes that I know can be controlled by passengers in the cabin and overridden in the cockpit.
Cabin heat comes from engine bleed air. Demand on this air can vary. It's used for pressurization, heating the wings for ice protection and for cooling the engines. If demand for cabin heat is high it could compete with demand for more critical uses (e.g. ice protection). So I would be very surprised if there wasn't full control in the cockpit.
