AC and In Command wont communicate

[drjbucknerdc]

I have a Keyston Fuzion. My In command system isnt communicating with my AC/ Heat system. I called In Command and they took me through it and that was the conclusion. Any idea why my 3 ACs arent communicating with the In command? He said it was a gateway issue but didnt know where to start because it was outside his system. I called Keystone to see if there is a main breaker somewhere or if it could be an issue with the inverter. They refused to offer any guidance. They said "take it to a dealer?" But I want to see if I can knock it our first. Anyway. I tested the AC power lines (thank to the advice of a guy on here) Lines in and out of the Inverter/converter. They are live. All 12v systems work. I assume the ACs are the only thing on 120? Any advice you can give would be helpful.

It seems there are not responses to your issue here. But it would help me, and probably others, if you would post your follow up progress and hopefully the solution.

Thanks

Is your iN.Command system up to date? Upgrades may be available on the ASA web site. Our AC/heat system is not linked to iN.Command in our 2018 trailer so I can't personally speak to this problem. However, it sounds like you may have a "thermostat" issue. How about calling the AC manufacturer (Coleman?) and asking them about the gateway. It seems like I recall someone saying the gateway may be integral with one of the AC units.

Lastly, pull the cover off of the iN.Command system J-box in the pass through storage area. Inside the cover, there will be a wiring diagram that lists everything connected to iN.Command. Look to see if there is anything in the system that connects to a thermostate, gateway, or the AC system.

When you get it all working again and want to run all 3 AC units at the same time, PM me and I'll get you more information.
