The answer to 'zone control system or zone control system' is that a zone control system is a more advanced HVAC setup that allows you to independently control the temperature in different areas or 'zones' of your home. This can provide better comfort and energy efficiency compared to a single thermostat controlling the whole house.
Zone control systems use multiple thermostats and dampers in the ductwork to regulate airflow to each zone. This allows you to heat or cool only the rooms you're using, rather than wasting energy on empty rooms. Zone systems are particularly beneficial for homes with open floor plans, multiple stories, or rooms that get more or less sun exposure.
