2008 American Coach Tradition Air Conditioning

[scott98]

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.

Hi Scott,

Welcome to FMCA !!

Could you post the make and model information of the controls (thermostat and control circuit board) for your AC and Heating system for the group.
