Description
The Reznor 112751 Blocked-Vent Switch is designed to protect the HVAC system by shutting down the system if the vents are blocked and the system overheats. For vent safety, it operates at the temperature of 200°F. It checks the airflow through the vent and goes off when the temperature rises beyond the permissible limit, indicating a blockage of the vent. The switch cuts off the electrical circuit to stop the operation of the unit to avoid the risks. It is widely applied in furnaces and heating systems to increase the safety and durability of the equipment.
