Since my basement gets kinda cold 50-60F during the winter, and up to the low 70s in the summer..
And the outdoor temperature can jump up above the 50-60 range, even during the heating season..

Does an ASHP hotwater heater need two coils and two compressors?

This might be a good app for the CAI controller board, since I would
need to monitor a bunch of temperatures (5?) and control some individual motors.

I'm considering this scheme because I happen to own a couple of small
window AC units that aren't going to be very busy this summer..

Comments please:
