Original title: The principle and wiring method of the thermostat What does the "total, high, and low" of the thermostat mean?

thermostat is a common automatic temperature control system, such as floor heating electric water heaters and central air conditioning drying boxes used in homes. these are all stored in temperature control system software.

The principle of the thermostat

The principle of the thermostat is also the operation principle of the thermostat. The temperature opinions accurately measured by the temperature camera connected to the temperature camera of Wang Hong are fed back to the CPU. According to the error between the resolution and the set temperature, the data signal of the automobile relay is given to distinguish whether it is heating or cooling, thus enabling the temperature control system software to achieve a balanced and accurate situation.

the PID temperature controller is the principle. the following figure is a simple schematic diagram of temperature control. the temperature controller gives full play to the effect of CPU in the system software, among them, the output automobile relay can select SSR intermediate relay and DC contactor. The intermediate relay has very good precision effect in the temperature control system software, and single pulse heating can make the temperature more symmetrical.
