effectively cutting the burner circuit if the heat exchanger exceeds safe operating temperatures
Professional technicians rely on the HN67QG005 for its consistent timing cycles and robust thermal resistance
The solid-core design ensures accurate induction across the sensing circuit
Enhanced Durability: The 3-tube burner assembly utilizes 409-grade stainless steel to resist oxidation and thermal fatigue
Watts F256661 Valve 320720-756 effectively cutting the burner circuitThe Watts F256661 140S 3 150 210 FS is a freeze stat temperature limit control used in HVAC systems to protect coils, heat exchangers, and air handling equipment from low temperature damage. It functions by monitoring temperature and initiating a control response when conditions approach unsafe levels, helping prevent coil freeze up and system failure. In the field, this type of control is commonly used in air handlers, hydronic coil assemblies, and
