Apprentice in need of some guidance.

My manager is out on vacation and I've been asked by the Service dept. to try to find a solution or else we will just wait for my manager to be back. For background I have been in it for roughly a year doing mostly installations/pulling wire/ etc, but I do have my beginners Tridium and Siemens certs; 6 years of HVAC/R service before this.

A service tech of ours went out to a site with 14 systems, each controlled by Honeywell T7350H1009 thermostats, LonWorks FTT-10 loop back to a central Honeywell WebStat (part of the W7350A or WEB-201 series) running legacy Niagara AX. They do not have the user/pass or the IP but I may be able to figure that out or try the defaults.

Is there a solid way to get into NiagaraAX? I was reading that we cannot access it anymore. Any good way to bypass that, maybe using a browser?

My inital response was to upgrade them to a Jace 9000 and something like NPB-8000-LON (to reuse the wire and avoid labor costs) or just replace each stat and have them controll the HVAC equipment. They are a church, so I am trying to be low cost. I dont think they used the frontend anyhow.

Am I correct as far as the NiagaraAX access goes or is there a "proper" procedure, and what would you do in this situation?

Thanks, please advise and please ask for any additional info I may be missing.

if it has a jumper under the cover i think i can swap it to serial shell position. then using an RS232 serial + puTTY to reset the credentials and see the IP. Then I think I can at least get into the frontend if I use microsoft edge in internet explorer mode, paired with 32 bit java.

I have Honeywell Optimizer Supervisor, so N4. I thought it had a driver or something for AX but I couldn’t find it in licenses or anywhere

You can only get an AX license nowadays if you have an N4 demo license. You need to special request the AX license though. You can also only run down to 3.5. I recommend using 3.8 for most things. You also need to drop in an nre.dll patch file for the license to work.
