We have different thermostats so we'll David to weigh in here as he has what you have. Two points though, I could never run 3 ac's on the generator. One would always overload the system and automaticity shut one down. When I manually start any of mine, the motor starts first pulling about five amps. Then about five minutes later, the compressor kicks in and a momentary spike of thirty amps happen and the system settles in at 12-15 amps steady state.

Good stuff
Yours works like I think it should, except the overload condition. Motor starts fan only, compressor pulls in after delay with a little spike.
Mine can be started under a load resulting in a locked rotor!
Not good...

OK,
So I WAS SUPPOSED to be working out in my garage this am on other punch lists, BUT it is so cold, I decided to fire up the puter instead of the phone since I still type like an infant on that thing and kabbits with you guys! Yeah, I do not know how your thermostat is wired hopefully David can help here, I have the old manual kind. I do know a little about programmable thermostats though, mostly in houses here in Florida for heat pumps and what I can say is there is definitely a compressor delay programmable option in these things. It's either a true software program option located under the technicians password or a hard wire to a certain pin......They messed that up when we had a new system installed recently and the system was behaving like your AC's are, both the compressor and motor started at the same time. As for my overload shutdown, yeah, every time I try and bring up 3, the last one I bring online fires up the motor but won't start the compressor and just shuts down.......been like that since I got the coach, never bothered to troubleshoot it but I did check all the wiring and relays and they are good.
Duh, Just saw David's post after I wrote this, Thanks David!!!!! I knew you would have some insight!!!!! :-)
