Differential Тhermostats

A differential thermostat is a device that controls temperature systems based on the difference in temperatures between two points, rather than absolute values. It is used for more precise control in heating and cooling systems, especially in multi-zone installations. Its applications include heating, ventilation, and air conditioning systems, solar water heaters, and industrial processes where accurate temperature control is required.
