For example: Adjust the temperature of a certain scene. The actual value is 26℃, and the set value is 25℃. The cooling will only start when the ambient temperature is higher than 25+1, and stop when it is lower than 26-1. When the intermediate value is between 24 and 27, the equipment will rest and not be disturbed. The temperature range that is not disturbed (24 to 27℃) is the dead zone of the temperature controller.

For instance, in the commonly used ovens we live in, there is a "dead zone" in between when the heating tube is turned on and off. This way, the temperature will neither fluctuate wildly nor suddenly stop. This is very good for the sustainable applicability of the equipment.

To sum up

The "dead zone" does not mean that the equipment is broken; rather, it is a buffer stage for the equipment, which significantly reduces the damage rate of the temperature controller

2. The dead zone is too small: The device will frequently turn on and off, which can easily damage the equipment

3. Excessive dead zone: If the dead zone is too large, the temperature fluctuation range will increase, and the accuracy will also increase accordingly, affecting the final effect

4. Reflux value: The difference, that is, 60 degrees in summer, with a dead zone of 2 degrees, the temperature will drop to 58 degrees before heating, and then gradually rise to 60 degrees
