Refer to you A/c manual/ documentation

Current a/c units have "preset" either a 15 second or 2 minute delay before compressor kicks "on" to bleed head pressure in the event of "brown-out" power interruption. My Duo-Therm 59136's has the preset 2 minute delay.

IMHO.....{If you have confirmed this 2 minute window}...I agree that the OP could leave t'stat powered "ON" and set to desired temperature & it will be sufficient delay for generator start-up to equalize.

Confirmed and agree with ability to leave thermostat in "on" position and start generator as needed.

I switched breakers to both compressors off, set thermostat to on and a lower than ambient temp., switched breakers on, and timed = 1 minute 53 seconds and compressor started. Seems to me to be safe way to go.

Only info I could get from the manuals was that there is a 30 second delay between compressor 1 and compressor 2 being able to start to prevent higher than detected supply amps.

Thanks for all the input from everyone - I'll eventually get this thing figured out, one system at a time - IF I live long enough.

well - I think you see where this is going

I don't know if it's a built-in delay, but I do believe the AC fan will run for a short period of time before the thermostat senses temperature and turns on the compressor, correct?

Yes, The fan comes on first followed by about a 3-5 second delay and then the compressor starts.

I turn off all heavy electrical loads, any time the power source is changed (don't forget about battery chargers/inverters). Much easier to be safe than sorry, no electrical device like to be switched under a load. Never had a problem except once with a lightning strike that hit near the power pedistal and blewup one of the transfer switches. That was a eye opener.

Our 2000 Adventurer has a GenSet Start/Stop Switch on the Dashboard. Seems to me that would be for using the A/C en-route without having to stop. (Or use the Cruise Control.)

I agree with Rick. I've been doing exactly what you described for years and never thought twice about it.

Thanks RJay.

Thanks. I hope this will save our members an unnecessary breakdown and an unexpected expense.
