Объявление переменной для объекта, который я создал в C++

Я парень с Java и пытаюсь сделать задание на C++ для класса. У меня проблемы с объявлением переменной созданного мной типа как свойства другого класса. Вот мой подход

  private:
    HeatingUnit heatingUnit;
    int tempToMaintain;

  public:
    BangBangControl(int tempToMaintain, bool isOn, int initialTemp){
      heatingUnit= new HeatingUnit(isOn, initialTemp);
      this -> tempToMaintain = tempToMaintain;
    }

Я получаю эту ошибку
