[Equest-users] Heat pump with furnace backup

[Carol Gardner]

Chris,

I looked at the online help and it said it was a valid choice only for a gas
heat pump. When I ran it anyway I got heat use but it was not reported in
the supplemental column. So, I am thinking that it is not a valid choice
anymore.

Regards,
Carol
