The numbers 1 to 5 on radiators do not indicate exact temperatures but rather approximate heating levels. These settings depend on various factors, including room insulation and furniture placement. The thermostatic valve regulates the heating based on the desired room temperature, which can be affected by the radiator's location and surrounding objects. Each number corresponds to a general temperature range, with 0 being off and 5 being the highest setting. Additionally, symbols like the snowflake indicate frost protection, while the sun and moon represent comfort and economy modes, respectively. Proper use of the thermostatic valve can enhance thermal comfort and reduce energy consumption.
