How does a Manual Thermostat Work ?
A manual thermostat is a simple yet effective tool for controlling the temperature in your home or office. It is a device that uses a bi-metallic strip to detect changes in temperature and then activates the heating or cooling system accordingly. A manual thermostat is made up of three main components: a temperature-sensitive bi-metallic strip , a mercury switch , and a set of contacts . The bi-metallic strip is made of two different metals that expand and contract at different rates when exposed to changes in temperature. As the temperature in the room increases or decreases, the strip bends and straightens accordingly. When the temperature reaches the desired level, the mercury switch tilts and completes an electrical circuit, allowing the heating or cooling system to turn on. Once the temperature falls below or rises above the desired level, the mercury switch tilts back and the circuit is broken, causing the system to turn off. One of the main benefits of a manual thermostat i...
