A pneumatic thermostat operates by using air pressure changes to control heating or cooling systems. It contains a diaphragm that responds to temperature variations; as the temperature rises or falls, the diaphragm moves, altering the pressure in a connected pneumatic control line. This pressure change signals the heating or cooling system to activate or deactivate, maintaining the desired temperature. Essentially, it translates temperature changes into pressure adjustments to regulate the climate in a space.
