A thermostat is an automatic temperature control device that plays a crucial role in heating and cooling systems, whether in homes, offices, or industrial settings. The thermostat detects and controls the temperature to maintain it at the desired level as set by the user, helping to save energy andincrease system efficiency.
What is a Thermostat?
A thermostat is a temperature control device used in heating and cooling systems, such as air conditioners, HVAC systems, or hot water heaters. There are both analog and digital types of thermostats. Thermostats are suitable for controlling temperatures within the range of 0-50°C (TS-050) or 0-90°C (TS-090). The principle of operation of a thermostat involves receiving input signals from temperature sensors, comparing them with the set point value in the range of 0-80°C for temperature and 0-100%RH for humidity. Then it processes this information and sends control signals to start or stop the system as appropriate, maintaining the desired temperature level.
What does a Thermostat do?
A thermostat is a highly efficient temperature control device suitable for various environments such as temperature-controlled rooms, food industry air conditioning thermostats, ovens, irons, greenhouses, and incubators. The thermostats from Sunchai Meter Co., Ltd. are specially designed to be user-friendly, reducing wiring complexity and addressing inaccurate temperature control issues that may damage equipment or materials. With these features, this temperature control device helps maintain precise standards for both temperature and humidity in production processes.
How does a Thermostat Work?
The basic working principle of a thermostat using a Bimetallic Plate relies on the shape change of two types of metal bonded together, with one side fixed and the other serving as an electrical contact surface. When the sensor detects heat and sends it to the bimetallic plate, applying electrical pressure causes the contacts to separate, breaking the circuit. Once the contacts cool down, the bimetallic strip returns to its original position, allowing the circuit to function again. This is the fundamental working principle of a thermostat used for temperature control in various systems.
What is the Difference Between a Thermostat and a Temperature Controller?
A thermostat and a temperature controller are both widely used in industries and daily life for controlling temperatures. However, they differ in terms of capabilities, accuracy, and applications. Understanding the differences between these devices will help you choose the right one to meet your specific needs.
Thermostat
A thermostat is a basic temperature control device that operates on an ON-OFF system, using two types of metals (Bimetallic Plate) to change shape as the temperature changes. When the temperature fluctuates, the thermostat will cut or connect electrical circuits to control heating or cooling devices, keeping the temperature within a set range. It offers basic accuracy and is suitable for general household use or equipment that does not require extremely high precision.
Temperature Controller
A temperature controller is a more complex and highly accurate device, working by receiving input from temperature sensors, processing it digitally, and sending output to control various devices. It comes in both Analog and Digital types, with several categories based on complexity such as ON/OFF controllers, PID controllers, automatic adjustment controllers, and multi-loop controllers. These provide high accuracy and are suitable for industrial applications, laboratories, or systems requiring precise temperature control.

Summary
Thermostats are crucial temperature control devices in various systems, whether it's air conditioning, heating systems, or industrial systems. The operation of a thermostat relies on the physical changes of materials when temperatures change, or uses electronic sensors to detect temperature.
Thermostats differ from temperature controllers in terms of accuracy and control principles. Thermostats typically use simple on-off systems, while temperature controllers often employ more accurate PID control systems.
Selecting the right thermostat for your system can enhance performance, save energy, and extend equipment lifespan. For additional advice or installation inquiries, SCMA Company is ready to serve with expertise and experience.
Frequently Asked Questions
When it comes to thermostats and temperature control systems, there are always questions that users have about how they work, the differences between devices, or choosing the right one for their needs. We've compiled a list of frequently asked questions to help you better understand thermostats.
What does a thermostat do?
A thermostat controls temperature by automatically turning electrical circuits on or off as the temperature changes. It detects the temperature in the system or area to be controlled, compares it with the set value, and commands the system to start or stop working to maintain the desired temperature level. Additionally, it helps save energy and prevent damage from excessively high or low temperatures.
What is thermostatic?
Thermostatic is an adjective used to describe systems or devices that work based on the principle of a thermostat, or have automatic temperature control. For example, a thermostatic valve (thermostatic valve) can automatically adjust fluid flow according to temperature, or a thermostatic mixing valve adjusts the ratio of hot and cold water to achieve the desired temperature.
What does normally closed mean for a thermostat?
A normally closed (NC) thermostat means that in normal conditions (when the temperature is below the set value), it remains in an open circuit state, allowing electrical current to flow. When the temperature rises to the set value, the thermostat closes the circuit and stops the flow of electricity. This type of thermostat is often used in heating systems to cut off heater operation when the desired temperature level is reached.
What does a thermostatic switch do?
A thermostatic switch (thermostat switch) is similar to a thermostat but is often used more for safety than regular temperature control. A thermostatic switch cuts off the electrical circuit when the temperature exceeds the set value, preventing damage from excessive heat, such as in electric motors, boilers, or various electronic devices. Some types of thermostatic switches can reset automatically once the temperature drops, while others require manual resetting.
