Lämpösäädin, often translated as thermostat, is a device that senses the temperature of a system and performs actions to maintain the temperature at a desired setpoint. In its simplest form, a thermostat can be a mechanical device that uses a bimetallic strip or a gas-filled bellows to detect temperature changes. When the temperature rises above a set point, the strip bends, closing an electrical circuit that activates a cooling system. Conversely, when the temperature drops, the strip straightens, opening the circuit and turning off the cooling system.

Modern thermostats are typically electronic and incorporate microprocessors, allowing for more sophisticated control and features. These electronic thermostats often use thermistors or thermocouples to measure temperature with high accuracy. They can be programmed to adjust the temperature at different times of the day or week, leading to energy savings. Smart thermostats take this a step further by connecting to Wi-Fi, enabling remote control via smartphone apps and learning user preferences to optimize heating and cooling schedules automatically.

The primary function of a lämpösäädin is to regulate temperature in environments such as homes, buildings, and industrial processes. By maintaining a stable temperature, it ensures comfort for occupants, prevents damage to sensitive equipment or materials, and contributes to energy efficiency. Common applications include residential heating and cooling systems, refrigerators, ovens, and industrial climate control. The accuracy and responsiveness of a lämpösäädin are crucial for its effective operation.
