Many household appliances and large equipment products will be installed and used thermostats, thermostats will be combined with the change of ambient temperature in the switch when working physical deformation, which will produce some special effects, so as to produce on-on or disconnection action, in order to achieve the purpose of automatic control components. Nowadays, people have a lot of questions about the wiring method of the thermostat, how to wire the thermostat?
The working principle of the thermostat is to automatically monitor the ambient temperature through the temperature sensor, and when the ambient temperature is higher than the set value range, the control circuit will be activated. If the temperature is still rising, the overrun alarm function will be activated when the temperature rises to the set overrun alarm temperature point. If the temperature cannot be effectively controlled, in order to prevent electrical equipment from being burned out, the equipment will be tripped to prevent the equipment from continuing to operate. At present, the thermostat has a wide range of applications, and can be used in high and low voltage switchgears and dry-type transformers and other equipment.
The wiring of the thermostat is the connection of input and output, as long as the connection of these two parts is done, then the power supply can work normally. The thermostat is a kind of control mechanism, so it needs a sensor that can collect external signals, so the thermostat has an input terminal, combined with the different models of the thermostat, there will be different requirements for the voltage and the number of wiring, and the wiring requirements of the thermostat must be understood first when connected.
The thermostat is still an execution structure, so there will be an output terminal, the output end is used to execute the signal for the execution structure, and the output terminal and the input end will be marked with letters, which determine the specific number of wiring and methods, so in order to make the thermostat work normally after connection, it must be combined with these contents for wiring.
The alarm device of the thermostat and the connection method of the power supply are also very simple, the alarm device belongs to a common end, which needs to be connected in combination with the model of the thermostat, and the connection of the power supply should meet the voltage requirements, and the power supply of the general thermostat has 80-220V AC and 24V DC/AC 2 kinds of power supply.
The above is an introduction to the working principle of the thermostat, as well as a brief introduction to the input terminal, input terminal, power supply and alarm device connection method of the thermostat, in order to make the wiring work of the thermostat more safe and smooth to complete, it is necessary to be engaged in this work by professionals.

RK Thermostat - Part of the LCD shows the status quo of floor heating thermostats
1) The LCD interface is too large or the display symbols are not proportional or standard.
2) The terminal blocks or circuits (components) that control the output cannot withstand large currents.
3) The cable of the external sensor (ground probe) is a thin and flexible wire, which cannot be inserted into the embedded pipe, and it is also a hidden danger for future maintenance.

Common faults and solutions of RKC temperature controllers
1. The power indication is normal, but the temperature controller has no screen display. Most of this fault is caused by the heating of the voltage regulator element (7805 or 7812) on the thermostat during long-term use, which leads to the breakpoint of the solder joint, and sometimes it is caused by the phenomenon of virtual soldering at the factory, and the main re-soldering can be done.
