Hello: I just purchased a 2015 Fleetwood Expedition Model X. I do not understand how the Zones work on the RV Comfort.ZC. It shows Zones 1, 2 and 3. Zone 1 is the front, Zone 2 is the bathroom and Zone 3 is the bedroom. It's Zone 3 that I don't understand. When set to Heat it shows the current temperature but the up and down buttons do not do anything. I can't set a temperature for Zone 3 and I get no heat. The AC works fine. The other 2 Zones work fine. Am I missing something on how to set Zone 3?
Thanks for any assistance.
