1.Core Functions
\nTemperature Setting
\nAllows the user to set a target temperature value (e.g. set the oven to 180\u00b0C and the refrigerator to 4\u00b0C).
\nTemperature Measurement
\nReal-time monitoring of the current temperature through sensors (e.g. thermocouples, thermistors, RTDs, etc.) and display on the controller screen.
\nDeviation Display
\nDisplays the difference between the current temperature and the set temperature (\u0394T) to help users understand the system status.<\/p>\n
2. Control Mode
\nSwitch control
\nThe simplest control mode: start heating when the temperature is lower than the set value, and shut down when it is higher (or reverse control cooling). Suitable for scenarios that do not require high precision (e.g. home air conditioning).
\nProportional control (P control)
\nOutput power is proportional to temperature deviation, reducing temperature fluctuations.
\nPID control (Proportional-Integral-Differential)
\nDynamically adjusts the output through an algorithm, combining \u201ccurrent error\u201d (P), \u201caccumulated error\u201d (I), \u201cchange trend\u201d (D), to realize high-precision, fast and stable temperature regulation. (Commonly used in industrial furnaces and laboratory equipment)
\nFuzzy control\/adaptive control
\nOptimize the response through intelligent algorithms for complex non-linear systems (e.g. advanced thermostats).<\/p>\n
3. Output control mode
\nRelay output
\nControl the on-off of heater\/refrigeration equipment, suitable for high power equipment.
\nAnalog output (4-20mA, 0-10V)
\nContinuously adjusts actuators (e.g., control valves, inverters) for smoother temperature control.
\nSSR (Solid State Relay) drive
\nHigh-frequency switching control, suitable for scenarios requiring fast response.<\/p>\n
4. Protection and Alarm Functions
\nOver Temperature Alarm (OT)
\nTriggers audible and visual alarm or automatic power-off when temperature exceeds the safety threshold.
\nSensor Failure Detection
\nDetect sensor open circuit or short circuit to avoid system out of control.
\nDelayed start
\nPrevents frequent start\/stop damage to equipment (e.g. compressor protection).
\nSelf-diagnostic function
\nRegularly detects the internal status of the controller to indicate abnormalities (e.g. communication failures, power fluctuations).<\/p>","protected":false},"excerpt":{"rendered":"
