I'm just about settled on my new system selctions, but -
Do the Carrier Infinity's - 25HNA9,6 - all talk on a network (ie, not have normal Y, W, etc. terminals for interconnecting)?
If I drop down, to Performance, or Comfort (25HPA, 25HCA) do I then get back to regular style control interconnections?
I will need to interface to an existing AS 90 furnace, and I don't want to get stuck in a control issue where I have to a pitch a good furnace because it doesn't 'talk' Carrier.
Also, are all of these versions listed TXV types or do they have some version of a flowrater type device (for indoor coil)? Does that TXV normally come with the coil (without being listed seperately on the specs)?
