Description

The Marley Engineered Products 4520-0010-000 Fan Delay Relay (F130-20F) is a temperature-sensitive control device designed to delay fan operation in HVAC heating systems. Commonly used in unit heaters and electric furnaces, it activates the fan after the heating element reaches a specific temperature (130°F) and turns it off once it cools to 120°F, ensuring efficient heat distribution and preventing cold air blow. This relay enhances system performance, extends component life, and improves comfort by maintaining optimal airflow timing. Its reliable thermal sensing design supports safe and energy-efficient HVAC operation.

For an efficient and reliable HVAC system, the Marley Engineered Products Fan Delay Relay is a great choice for optimal system performance.
