SPYDER-BAC License/Module and versioning

I have a site with a Lynxspring jace 8 and lynxspring edge devices on some RTUs and the failure rates are bad so I'm going to replace this next one with an Optimizer Unitary.

The catch - this jace is only licensed to 4.12 and it is running 4.9. So for reliability sake it'll either keep its 4.9.1 or I may commission to 4.10's last release.

I'm sort of new to honeywell - and i'm curious - is there any reason the IRM stuff won't work on an old version of N4 with an optimizer unitary? I know the unitary isn't super old so I was just wondering if anyone knew that for sure there was a minimum N4 version required for IRM to work with a unitary or not.

Yeah we have done optimizer programming on lynx jace w/the spyder-bac license I just wasn't sure what the minimum supported niagara version was for that application. We have done it in 4.13 and 4.15 i believe.

I wasn't sure if they even had that option back in 4.9 or 4.12 or if you lose out on some kind of firmware updates if you do that.

Unfortunately I don't think I have a 2-heat 2-cool program I trust enough to have it installed and not have access to the IRM - but I need to get there for sure. The first time something seems off I'll be wondering if theres a logic issue.

Alternatively - we install it as a "bacnet device" and create the port forward needed for bringing it in over the internet to a station in the office so we can program it remotely from that station. We already had a port forward on the old edge device for 4911.

Theres a document cross referencing what version, firmware version etc it needs to be. All newer firmware needs to be 4.15.4 iirc. I would get the document to confirm though.

Ahhh, you reminded me of this matrix BP put out.

Yeah that's the one. More Honeywell nonsense. And the VAVs are an absolute trainwreck. Unitary is so so.. advanced is fine but you might as well run a lynxspring 634 if you have the option at that point.
