What component is wired in series with the anticipator on a mid-efficiency induced draft furnace?

The integrated circuit board is wired in series with the anticipator on a mid-efficiency induced draft furnace because it plays a critical role in the control and operation of the furnace's heating elements. The anticipator works to regulate the furnace's temperature by sensing when the desired temperature is reached and adjusting the thermostat's output accordingly.

When the anticipator is functioning properly, it signals the integrated circuit board to manage the furnace operations based on the detected temperature. The circuit board processes these signals to activate or deactivate components such as the gas valve or the inducer motor, ensuring that the heating is efficient and effectively controlled.

In mid-efficiency furnaces, this series configuration helps maintain a balance in the system, allowing for precise temperature control, which is essential for efficient heating and energy use. Understanding how the integrated circuit board operates in conjunction with the anticipator emphasizes the importance of utilizing electronic components in modern HVAC systems for improved performance and reliability.
