The Trane KIT17858, a 24-volt, two-stage HSI control, acts as the furnace's core intellect to provide ideal heating. Because of its dual-stage operation, it can adjust the heating level to the changing environment. It uses less energy and produces less noise while operating in a low-stage mode at moderate temperatures. But as the temperature drops, it switches to high-stage mode with ease, delivering strong heating to keep people comfortable inside. Its hot surface ignition technology guarantees consistent, safe operation of the gas burner at all times. This control system is built to last because of its features and long-lasting materials, which also provide user confidence. For homes looking for a trustworthy, quiet, and efficient heating solution, the Trane KIT17858 2-Stage HSI Control is a wise option for compatible Trane systems.
