We are looking at a possible staged upgrade path for our Dual VAV controllers. Our current installation is an old (approx 10 years) Honeywell C-Bus system, and the reason for upgrade is that the multicontrollers above the VAV controllers are failing and no longer being made.
We are in the progress of upgrading to EBI from XBS, but instead of that bag of worms, I'd like to instead ask: What is the new VAV control from Honeywell? The only thing I can seem to find is Excel 10s, which still look like they operate on C-Bus. I'd like to get everything onto something more standard, especially if we have to do a large upgrade that replaces sections of our system at a time.
We also need fan coil control, but everything else is on custom DDC controllers which look like they have a better upgrade path. Any suggestions? Thanks!
