WRONG on the 4 buttons. Here is how you change zones. Doug

The front area could be established as
ZONE 1 and the back section ZONE 2. You can select
the desired temperature and fan speeds for each zone
independently, thereby keeping your bedroom cooler
than the front portion of the vehicle. To determine the
number of established zones in the vehicle, simultaneously
depress the FAN and MODE push-buttons.
Zone 1 will be the first Zone to appear in the LCD
readout. Continue to depress and release these buttons
until you see Zone 1 reappear. Zone 2 will then appear.

Do you have the Dometic 4 button wall Tstat that has the LCD screen? If so, it will have 2 zones----zone 1 and zone 2. ONLY zone 1 has the furnace display. So check at the bottom of the LCD display and determine which Zone is indicated. Doug
