The Model 6404 is designed to work with your heating and cooling
system, whether it is a furnace and air conditioner type system or
a heat pump. This model can handle three stages of heat (two
stage compressor, one auxiliary heat) and two stages of cool. The
6404 itself will control 2, 3 or 4 zones. However, the system can
have as many as 12 zones by adding expansion panels.
