USA automatic temperature control square diffuser

Each ZDA type diffusion box per layer is formed by stamping. Installed on the ceiling, the temperature sensor can automatically detect the supply air temperature in the air duct, adjust the blade height, and automatically adjust the airflow direction. In summer, when the room is cooled, it blows horizontally; in winter, when the room is heated, it blows vertically. The sensor uses a temperature-sensing type and does not use electricity. The cooling temperature is below 17℃, and the heating temperature is above 28℃. After the temperature sensor is activated, it is in a cooling or heating state.
