That depends on whether or not the tank will go above the desired temperature. So, you need to think about the things you'll be hosting and see what temperature is good for them. Then you need to see how your lighting may affect the water, then of course the room temperature will affect it.
I do not run a chiller, nor a heater. I keep the room temperature between 76/78. Which is basically the temperature of my tank.
