Dometic Bluetooth CT auto fan and furnace fan behavior

Dometic Bluetooth CT instructions say Auto fan varies by the difference between setpoint and room temperature, and Furnace mode leaves the air-conditioner fan off in Auto while Low or High keeps that fan running continuously.

Owner-safe checklist

  • Record mode, setpoint, room temperature, and whether Fan shows Low, High, or Auto.
  • Treat normal Auto fan speed changes as expected when room temperature approaches the setpoint.
  • In Furnace mode, select Auto fan if extra air-conditioner circulation is not desired.
  • Use Low or High only when continuous fan circulation is desired.
  • Call qualified RV HVAC service if display selections change but fan behavior never matches the selected mode.
