rtinnman Report post Posted July 23, 2019 I have Voltage 5th wheel with 3 Dometic air conditioners. The bedroom has its on a/c and thermostat. The living area and he toy hauler area has its own a/cs. The thermostat is a zone type for these two a/c. Pressing the zone button does not change zones. Is there something I'm missing or is the T-stat bad.
