Animation: how a wax thermostat works. the wax (blue) is inside a sealed chamber (gray) that contains a metal needle (silver). as the temperature increases, the wax melts, expands, and pushes the needle out of the chamber (yellow arrows). the rising needle switches on or off whatever device the thermostat is controlling. A thermostat that operates both heating and cooling units has two contacts at each end of the vial. when the vial tilts in one direction, the mercury flows to that end and completes a circuit that calls for heat. when the system is switched to the cooling cycle, the mercury flows to the other end of the vial to turn on the cooling. The basic working principle of a thermostat revolves around temperature regulation within your home. you first set your preferred temperature using the thermostat's buttons, display, or a compatible phone app. with this set, the thermostat then gauges the room's current temperature with its built in sensor or additional sensors.
