First of all, from the two working principles of temperature and humidity is introduced, and then the controller to control the principle of constant.
1, constant temperature: this principle is relatively simple, through the PID control can be realized, that is, in the temperature is higher than the set value to stop the heating (cooling) work, when the temperature does not reach the set value, the heating (cooling) work to open, and then control in a certain temperature range within the set value, to achieve constant temperature!
2. Constant temperature and humidity: This is in the first item on the basis of the principle of humidity control through the dry and wet ball contrast method (usually through the compressor for balance), this is a simple working principle.

The temperature rise required by the national standard: 3-5 degrees/minute, cooling: 1 degree/minute. The above setting requirements can be realized through the controller. Humidity requirements plus pure water (caution). Just for reference!
