Room Thermostat Working Principle and Wiring Method

Many household appliances and large equipment products will install and use room thermostats. When the thermostat works, it will physically deform inside the switch in conjunction with the change of the ambient temperature. This will produce some special effects, which will lead to conduction or occurrence. Disconnect action to achieve the purpose of automatic control of components. Nowadays, people have many questions about the wiring method of the thermostat. How to connect the thermostat?

The working principle of the thermostat is to automatically monitor the ambient temperature through a temperature sensor. When the ambient temperature is higher than the set value range, the control circuit will start. If the temperature is still rising, when the temperature rises to the set over-limit alarm temperature point, the over-limit alarm function will be activated. If the temperature cannot be effectively controlled, in order to prevent electrical equipment from being burnt out, tripping is used to prevent the equipment from continuing to work. The current application range of thermostats is very wide and can be used in high and low voltage switch cabinets and dry-type transformers and other equipment.

The essentials of the wiring work of the thermostat are the connection of the input and the output. As long as the connection of these two parts is done well, the power supply can work normally. The thermostat is a kind of control mechanism, so it needs a sensor that can collect external signals. Therefore, 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 wires. When connecting, you must first understand the wiring requirements of the thermostat.

The thermostat is still an execution structure, so there will be an output terminal. The output terminal is used for the execution signal of the executive structure. The output terminal and the input terminal will be marked with letters. These letters determine the specific wiring quantity and Method, so in order for the thermostat to work normally after the connection, it is necessary to combine these contents for wiring.

The alarm device of the thermostat and the connection method of the power supply is also very simple. The alarm device belongs to a common terminal and needs to be connected with the model of the thermostat. The connection of the power supply must meet the voltage requirements. Generally, the power supply of the 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 thermostat's input terminal, an input terminal, and power supply and alarm device connection method. In order to make the wiring work of the thermostat complete safely and smoothly, a professional is required to come to do this work.
