Depending on the outside temperature and the heating habits of residents, the heating requirements of rooms, apartments and entire buildings are constantly changing. Radiator thermostats and room temperature controller systems compensate for these fluctuations. Know how Indoor temperature controlling works in this Indoor temperature control quiz
