What are the factory settings for a standing pilot furnace with a bi-metal fan control?

The factory settings for a standing pilot furnace with a bi-metal fan control are typically designed to optimize the furnace's operation based on safety and performance standards. The correct settings ensure that the fan operates at the right temperature, maintaining comfort and efficiency without overheating the system.

In this case, the settings are provided as follows: the fan turns on at 125°F and off at a lower temperature of 80°F. This means that when the heat rises to 125°F, the fan starts circulating air to distribute the heat throughout the space. The fan then stops at 80°F, allowing for energy savings and preventing excessive cooling of the system. Additionally, the limit cut-out setting at 200°F ensures that if the furnace temperature exceeds this limit, the system will shut down, enhancing safety and protecting the equipment from damage due to overheating.

Understanding these settings is crucial for effective furnace operation, ensuring that the system runs efficiently while providing comfortable indoor temperatures. Familiarity with these parameters enables technicians to diagnose issues and maintain heating equipment effectively, aligning with standard engineering practices for heating systems.
