We offer Digital Thermostat element which senses the temperature of a physical system and performs action, after that the system's temperature is maintained near a desired fixed point. It has no moving part for measuring temperature, therefore it use semiconductor or other sensor in their processing to control heating or cooling. Both heating and cooling equipment runs at full capacity until the set temperature is reached and then it gets closed. Each screen shows the current temperature plus current setting. Most of them has a clock also. Basically, it is used for energy conservation and comfort. It is used in any system which cool or heat to a set point of temperature like air conditioners, ovens, refrigerators, water heaters and many more. The name is derived from the Greek word in which thermos means hot and statos means standing stationary.
