Just purchased a 2008 American Coach Tradition 42F Tag. I'm trying to figure out my air conditioners. I have three and they are on a three zone system that is set up as follows:

Zone 1: Heat (Aqua Hot 450), Fan, Cool (air)

Zone 2: Heat (Aqua Hot450), fan, Heat Pump, Cool (air)

Zone 3: Heat (Aqua Hot), fan, Cool (air)

My question is this... When I turn all three zones to cool, nothing seems to happen with zone 3. I found this out as I turned them on one at a time to test and nothing happens with zone 3. With zone 1&2 air on, all the vents are producing cold air, so what the heck does zone 3 air do?

strudeau,

What type of units do you have? I am presuming that they have the same operating functions on the controller such as heat pump, cool, furnace (Aqua Hot), fan setting and auto or not. You did not say whether you were running with the generator on or plugged in. In any event, all three ACs should be able to operate off of a 10K generator. If two are working and one is not, there could be an issue with the unit or try to operate zone 3 with the remaining two in the "off" position and see what happens.

I had a similar problem last July 4th 2012; however, it was apparent to me that I needed two new units which were eventually installed. Hopefully, yours is not the case.

Keep us posted.
