- ?ZONE VALVE CONTROL PRECISE HVAC FLOW MANAGEMENT –This replacement head features a Normally Closed (NC) design, remaining securely closed without power to prevent leaks. When the thermostat or Boiler detects a temperature deviation, it sends a 24V AC signal to energize the valve, overcoming the internal spring mechanism to open and allow chilled/hot water flow to the fan coil. Upon reaching the set temperature, power is cut and the spring instantly recloses the valve. This automatic open-close cycling maintains precise room temperature control while optimizing energy efficiency.
