I have a Lennox 2.5 ton heat pump along with a CBX32M air handler.
What i'd like to do is install a backup generator. A pretty large one
(22KW) but not large enough to power the heating system with the
electric backup heat which is 15KW in itself.
Can I just wire the compressor, and the air handler itself through the
transfer panel to get basic heat/cooling without the electric backup
heat? My theory being that it should be sufficient as long as its
not very cold outside. if that happens, then we can add space heaters
If that is possible, I think my problem is that the blower motor in
the air handler is wired in with the electric backup elements. Is
there a way to separate the blower and perhaps put it on the
compressor circuit instead, so that I can power that through by
transfer switch panel on a fairly modest ampacity circuit (about 15A
for compressor and 1.7A for the blower)?
