Zone valves are the easiest solution to control the temperature of the different areas of the system. A zone valve must be connected to a thermostat or to a chronothermostat, which opens or closes the valve according to the room temperature and to the selected comfort temperature. EMMETI zone valves Modulo and Modulo Compact are equipped with a end switch which closes when the valve is open, and can be used to turn on a circulator or a boiler.
