Markel 28470000 Relay
When you are dealing with inconsistent airflow or temperature stratification in commercial or residential HVAC systems, the Markel 28470000 Relay is the professional-grade solution for managing blower operations. As a veteran-preferred F120-40F Fan Delay Relay, this component is engineered to provide precise timing control, ensuring the blower motor continues to circulate air after the thermostat is satisfied. This process effectively harvests residual heating or cooling from the heat exchanger or evaporator coil, maximizing HVAC system efficiency and preventing the rapid short-cycling that leads to premature motor failure.
This SPDT fan relay operates on a 120 VAC circuit with a robust 20 A current rating, making it a versatile choice for a wide range of air handlers and furnace units. The adjustable fan delay settings allow technicians to fine-tune the delay from 10 seconds up to 10 minutes, optimizing the cycle based on specific ductwork requirements and equipment load. Designed for durability in demanding environments, its compact 1.5" x 1.25" x 5.25" base ensures a straightforward fit into existing control cabinets. Whether you are performing a Markel heater repair or upgrading a standard blower circuit, this relay provides the reliability required for consistent climate control.
Key Benefits for Contractors:- Optimized Thermal Management: Eliminates hot and cold spots by ensuring the fan extracts all conditioned air before shutting down.
- Broad Compatibility: Direct OEM replacement for various Markel, Raywall, and TPI Corporation heating and cooling models.
- Heavy-Duty Switching: Rated for 20 Amps at 120V to handle high-demand blower motors without contact pitting.
- Field-Adjustable Timing: Provides total control over the off-delay interval to match the specific thermal mass of the system.
How does this relay improve SEER ratings?
By running the blower after the compressor or heating element cycles off, the system utilizes the "free" energy left on the coils. This increases the total BTUs delivered without additional compressor runtime, directly boosting operational efficiency.
What is the primary function of the F120-40F model?
It serves as a time delay relay that prevents sudden temperature drops at the start of a cycle and ensures the equipment is sufficiently cooled at the end of a cycle, protecting the heat exchanger from stress.
Can this be used for both heating and cooling?
Yes, its SPDT configuration and adjustable timing make it suitable for managing blower delays in both furnace heating and air conditioning applications where 120V control is utilized.
