[Equest-users] VRF in eQuest

[Carol Gardner]

Hi all,

It's my pleasure to share information. I might be able to get some curve fit
info, too, but you will need to absolutely know what you are doing to
implement it. It is for when you are calling VRF/VRVs air source heat pumps.
NOT FOR WATER SOURCE. I will forward when I get it. You will use it only if
you are able to do so with skill!

Peace out,
Carol
