I managed to get it work with the following code:
   
    float getTemp(){
        #define ADDRESS 0x4C
        #define CONFIG 0x00
        float temp;
        Wire.beginTransmission(ADDRESS);
        Wire.write(CONFIG);
        Wire.endTransmission();
        delay(50);
        Wire.requestFrom(ADDRESS,2);
        temp=Wire.read();
        if(Wire.read()==128){
            temp+=0.5;
        }
        return temp;
    }
And connect the green wire to 3.3V, not to the 5V.
