Once the makeup water temperature returns to the safe range (5 degrees above the open set point, typically 40°F [4.4°C] ), the valve then modulates closed, minimizing water waste. Due to the sensing element, the thermal actuator, always being wetted this valve is unaffected by ambient air temperature and opens only when the water is in danger of freezing.
Relying on having to manually open valves for freeze protection allows for human error or plugging of partially cracked valves. This annually accounts for large amounts of freeze damage resulting in huge monetary losses including repairing damaged equipment and piping, as well as system downtime.
