6404 4-Zone Multi-Stage Universal Comfort Control™ Panel

Unlike conventional heating and air conditioning systems, Zoned Comfort Control knows, at any given time, which areas (zones) of a home require conditioned air and automatically directs the air to the zones that require it. This not only increase the comfort level throughout the home, but also conditions only the areas that need it, thus reducing energy costs.

The Model 6404 is designed to work with furnaces, air conditioners and heat pumps. This model can handle three stages of heat (two stage compressor, one auxiliary heat) and two stages of cool.
