ZCA temperature control circular diffuser

Mounted on the ceiling, it automatically detects the blowing temperature during cooling and heating, and automatically adjusts the airflow direction. During summer cooling, it blows horizontally. During winter heating, it blows vertically. The sensor uses a temperature-sensing type and does not use electricity. Cooling temperature is below 17°C, and heating temperature is above 28°C. After the temperature sensor is activated, it enters the cooling or heating state. The outer frame and blades are connected using an assembly method, without any welding points.
