Just purchased a new to me 2008 American Coach Tradition 42F Tag, with three roof air conditioners. I'm trying to figure out how this three zone system works.
Zone 1 when switched on clearly is for the front of the Coach, and has the Fan, Cool, and heat (Aqua Hot System)
Zone 2 covers the back half of the Coach, and has the Fan, Cool, Heat Pump, and heat (Aqua Hot System)
Both Zone 1 & 2 work in any of the above modes.
My question concerns Zone 3. Zone 3 has, Fan, Cool, and heat (Aqua Hot System). When I turn Zone 3 to cool, what is suppose to come on? When I turn this Zone on all by itself (cool) nothing happens. All breakers are good. Does this supplement the other systems when it's really hot?
Any help would be appreciated.
