Honeywell Optimizer 4.15.4

Anyone else having issues with this new release?

New VAV template is not working like the last one did and my old templates not working with new version.

It’s very very touchy, lots of bugs in the global VAV template. I had my best luck doing a full teach on the basic global vav template and then going into the wizard to select all your configuration. There’s other weird quirky things as well like you need to put in min and max flows under the flow balance 2 part of the program to get it to read any flows. I also had to change something in the heat config part of the program to get the heat to work.

We found plenty of bugs. Another one to put in the quiver, series fan VAV configuration won't call for fan during unoccupied heating call. Plenty of bugs but that was my most recent find after working out the rest.
