The Marley Engineered Products 1414-2020-000 is a precision fan delay control engineered for use with unit heaters and cabinet heaters. Designed to optimize comfort and system efficiency, this fan delay control manages the sequencing of the blower fan relative to the heating element — preventing the circulation of cold air at startup and ensuring residual heat is fully utilized after the heat source cycles off.
How It Works
The 1414-2020-000 fan delay control monitors heat exchanger or element temperature and uses a fixed setpoint range of 125°F (cut-in) to 35°F (cut-out). On a call for heat, the fan is held off until the heating surface reaches 125°F, delivering only warm air to the conditioned space. When the heat source shuts down, the fan continues to run until the temperature drops to 35°F, recovering all available residual heat and improving overall system efficiency.
