Duo-therm ac unit
I have a 2005 34XL Cardinal 5th wheel and am having trouble understanding the analog control for the A/C unit.
One setting is for system: "cool-off-furnace.
The second is for Fan: "on-auto.
The third is a switch for "Hi-Lo (fan speed).
The fourth is the temperture lever from 40 Fto 80 F.
With the system setting in the "off" position, when you put the Fan from "on to auto, the fan on the A/C unit starts up. This doesn't seem right as I figured if the system is in the "off" position, nothing should run or does the A/C fan come on just as a fan without activating the air conditioning. Even reading this I find it hard to follow but if anyone can understand what I'm saying and knows how this works, or if this is the way it works, I would be much endebted.
Thanks you: firelaw
