I'm having trouble figuring out how the aquahot ties into this. I know in the past if I turned on electric aquahot the ac immediately went to low speed. Here is what I see from the thermostat control wires.  

Cool        Fan      Aquahot          Wires that are hot at this setting
--------  ---------    ------------        ---------------------------------------
Low      Low        off                  yellow    red
High      High        off                  yellow    orange    black
Low      Low          ON                no change, but not relevant either
High      High        ON                yellow    orange    black  (no change)

Based on this things, I use yellow as compressor 1 (or low/low).  Orange as compressor 2, high/high. (yellow is still hot).
I only have 1 evap fan setting, high.
I have 2 condensor fan settings, high/low, depending on if both compressors are on.

I don't know what I would use red or black hot wires for... but maybe this is where i am missing something.

Thank you,
