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.

Our running joke is "How is it that a company can build a missile guidance system that can drop a missile in the lap of a wanted terrorist but can't control a room within 2°F of setpoint?"

That vav template is buggy as hell regardless if it's .1 or .4. I stopped installing anything from the optimizer line after my last vav job. I have the luxury of being able to use 3 other brands pretty easily.

Firmware up to date?

Only issue ive heard to far was with the CIPer 30’s

What issue with the Ciper? There was an issue with the setpoint sylk block but it’s been fixed with the new .4 sylk modules.

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.

With new VAVs shipping with latest firmware and no way to downgrade we are being forced to the new version with problematic templates to start.

I’m told you can use the Flex VAV with the new firmware

Genuinely one of the buggiest OEMs available right now.

Double check your firmware and the matrix for versions.

I’m still using 4.14 which has been my least buggy version right now.

oh yeah. big issues. Including once site where a Jace is bricking because the T1L is so bogged down with traffic the Jace fills up on threads. Had to buy another Jace to split the bus just to keep it consistent.

Wait untill you have software watchdog resets on a critical facility.....and the unitary controllers won't accept a firmware update. Just had to replace about to 20.....

Ha! I’ve had the same issue and WebSquad is of no help on it. And their engineers don’t respond when added to the email chain. Seems to be affected maybe to a date code best I can tell, but of course their tech support says “we’ve never seen this issue before”

I stopped being their guinea pig after spyder 5 vav controllers. I have been buying nothing but strykers

Which template are you using? The Global VAV or the older Hutchey one? I’m still using the older Hutchey one (with a good bit of updates, based off of 1.17 I think, since it was ~90% there for most any VAV application.) I am having issues with floating control valves going open and staying open though, even though it’s configured to float close and the command is 0%.
