    My TRANE 2TWR1024A "user manual" is worthless. I cannot figure out how many stages this thing has, or what actually determines "stages". It has supplemental electric heating strips for extra cold weather. Is this considered a "stage"?

    the outdoor unit is a single stage. If you have heat strips, they are inside in the air handler section. This gives you two stages of heat and one stage of cool.
