What is a reverse thermostat?

A reverse thermostat is a device that functions oppositely to a traditional thermostat. While a standard thermostat activates heating or cooling systems to maintain a set temperature, a reverse thermostat triggers these systems to shut off when a specific temperature is reached, allowing the environment to become warmer or cooler than the set point. This can be useful in applications where temperature fluctuations are desired, such as in certain experimental or industrial settings.
