Dometic CCC2 fan only or no cooling by mode and zone
Dometic CCC2 operating instructions separate FAN mode from COOL mode: FAN Low/Med/High runs the fan continuously, FAN Auto is off, and cooling only calls when room temperature is above the cooling setpoint in the selected zone.
Owner-safe checklist
- Wake the CCC2 display from normal buttons and confirm the selected zone.
- Select COOL mode instead of FAN mode before judging a no-cooling call.
- Confirm the room temperature is above the cooling setpoint and the fan setting is Auto, Low, Med, or High as intended.
- Wait through the normal cooling delay, then call qualified RV HVAC service if the selected zone requests cooling but does not cool.
