Are you two pipe or one? How many hooked to each radiator. If you are one pipe there is thrmostatically operated air vents by Honeywell, Ista, Danfoss etc. If you have two pipe there is valves as HK said. Two pipe you should be able to throttle the valve you have to cut the amount of heat. If one pipe, it is tough to balance. If you have very long cycles of heat the air vents are used as often and steam keeps coming to replace condensate. You can play with blocking the air flow over radiators. How many units in bldg? Where is the stat? It might be in the apt that has someone that likes it 95 with a t-shirt or they are fresh air freaks with their windows open. Diabetics, etc can feel cold too. If it is a condition that is transient like someone trying night setback, you might have trouble matching your rate of heat gain to your loss. Try closing off a radiator or two for a couple of days in areas that might get enough heat from others. Anything readers try should be done for a day or so to let things balance.
