Landmark Newport A/C

We just got our landmark newport it has 3 a/c, at walk through coach was ice cold and set a 72, we've had all 3 units at 70 and it's not as cold as yesterday at dealer, also all 3 are on auto but one in bedroom keeps running all have been running for over 7 hours straight...any ideas

Your thermostat to the one that is running has the fan set on either high or low. Change it to Auto and it will only come on or off when the need for the AC is there

Got it thanks for20hunter

About the three A/C option, how much generator power would be required to run all three (and the other stuff, like the inverter/residential fridge.)?

How about the Eu7000is Honda "portable" generator? If we went with the popular pair of Honda 2000s, I suspect we could only run one A/C at a time. Is it possible to separate control of the A/C units to select the one we want to run?

Thanks,

Roy
