MaxxAir 4/5/6 key wall-control service prep
Use the MaxxAir wall-control operation instructions to document display behavior, Auto thermostat behavior, fan speed, IN/OUT direction, open/close commands, and rain-sensor beeps before service.
Owner-safe checklist
- Record wall control display state, button response, fan speed, IN/OUT direction, open or close behavior, Auto mode, setpoint, and rain-sensor beeps.
- Use only normal wall-control buttons and normal fan controls to compare behavior with the operation guide.
- Stop using the control if the fan fails to respond, responds unpredictably, or the display behavior does not match normal operation.
- Use MaxxAir or qualified RV ventilation service for repeated wall control, display, fan response, or rain-sensor symptoms.
