What do you mean "until I got temperature control on my heated bed"? If you can turn heat on at all, you should be able to set its temperature. What printer and software are you using? In GCODE you should see something like M190 S110, which would set the heated bed to 110 degrees, and if you change 110 to, say, 50, that should make PLA happy. Lots of people are printing PLA on an unheated print bed, but I've had much better luck printing on 40-50 degree heated bed than unheated.
