Dometic CCC2 auto change-over behavior prep

Use this CCC2 guide when AUTO change-over behavior needs documentation across heat, cool, zone, and setpoint conditions before service review.

Owner-safe checklist

• Record the CCC2 zone, selected mode, heat and cool setpoints, room temperature, and whether AUTO changes between heat and cool as expected.
• Save photos of the thermostat screen and note which roof or furnace equipment is connected to the zone.
• Use qualified RV HVAC service for thermostat, zone-control, rooftop, furnace, or installed climate-system decisions.
