Description
The Reznor RZ123976 Fan Control with Bracket is a temperature-based control switch that regulates fan operation by responding to heat levels in HVAC systems. It is set to close at approximately 40°F and open at around 135°F, allowing automatic fan activation and shutdown based on temperature changes. This control is typically installed in unit heaters or furnace assemblies, where it monitors internal conditions. Its role in the system is to manage fan cycling, helping maintain proper airflow and preventing overheating during operation.
