Not sure what you mean. I'm referring to this: Vykon HVAC. It is Jace2 and 6 (I believe they are available in US) with special jar modules.

I have seen it done twice (by the same company) with R2 Jace with onboard IO and also Honeywell LON IO in the larger panels. Lon was also used for the VAVs and also Modbus for Metering. Small fixed application LON IO for tenants metering and miscellaneous monitoring/control.
It worked well and I assume is cost effective otherwise they would not have used this approach.

A other option
I have done it a few time. No problem.
You could also consider the honeywell Spyder. Smaller controllers, availables with BACnet or Lonwork network and they are program with Workbench. They are Niagara AX base controller.
Using Spyder ctrl's network to a WEB-201 (Jace-2) would cut your price even more, with the same benefit of using only Jace-2.

I agree and if you have a java programmer around you can do it in baja. I have developed a generic ahu block for 90 % of the ahu's we do. I use th jace for this all the time. I use cat 6 or lon depending on whats going on.

If you write a generic ahu program (java or block) you can use it over and over again. Set up time becomes short, hours drop and more money made.
I wouldn't plan on using a WEB-201 if you need access to the programming tool after installation. See the HW Spyder compatibility matrix, I don't think HW supports the tool on a 201.

New Spyder tool will allow to program on the JACE. It doesn't take any additional memory compare to dynamic device. The program is loading to the memory only when you see wire sheet and unloading as soon as you switch to another one.
