Скачать или смотреть How Twinning Gas Furnaces Works: A Technical Guide (Part- AGATWNPUA01A) - PartsHnC

Twinning is commonly used when space, duct design, or capacity limits make a single furnace insufficient. In this setup, both furnaces must operate as one system, with blowers starting together and burners firing in sequence. Correct wiring and control logic are critical to ensure safe operation, proper airflow, and efficient heat delivery. Understanding how this works also provides insight into the Parts of a Residential HVAC System and how different components interact under load.
