  1. Locate the Breaker: Identify the circuit breaker that supplies power to your Senville air conditioning system. This is typically located in your home’s electrical panel or a dedicated HVAC breaker box.
  2. Flip the Breaker: Completely power down all units by flipping the circuit breaker to the “off” position. This will cut power to the entire Senville system.

Entering Test Mode

  1. Timing is Critical: Within one minute of turning the breaker back on, you must initiate the test mode sequence. Precise timing is essential for this process to work correctly.
  2. Accessing the Service Mode: Press and hold the power and fan buttons on the remote control simultaneously for approximately 7 seconds. This will enter the service mode menu.
  3. Navigating the Service Menu: Press the up arrow button twice to select setting 2, then press the power button for 2 seconds to confirm your selection.
  4. Scrolling Through Test Options: Use the cursor buttons on the remote to scroll through the available test mode options:
  5. Option 1: Fan stop
  6. Option 2: Fan runs at lowest RPM
  7. Option 3: Fan runs at setting RPM
  8. Option 4: Fan stops for 5 minutes and runs for 1 minute
  9. Option 5: Fan stops for 10 minutes and runs for 1 minute
  10. Option 6: Fan stops for 15 minutes and runs for 1 minute
  11. Option 7: Fan stops for 20 minutes and runs for 1 minute
  12. Option 8: Fan stops for 30 minutes and runs for 1 minute
  13. Option 9: Fan stops for 40 minutes and runs for 1 minute
  14. Option 10: Fan stops for 50 minutes and runs for 1 minute
  15. Option 11: Fan stops for 60 minutes and runs for 1 minute
  16. Selecting the Test Option: Once you have chosen the desired test mode option, make sure the remote is pointed directly at the Senville unit. Press the “OK” button to confirm your selection.
  17. Observing the Display: You should see the display on the Senville unit flash quickly, indicating that the test mode setting has been updated.
  18. Exiting Test Mode: To exit the test mode, press the power and fan buttons on the remote control simultaneously.

Important Considerations

  • Timing Sensitivity: The entire test mode activation process must be completed within one minute of the power being restored to the Senville system. Failing to do so will require you to repeat the entire sequence.
  • Cassette Unit Variations: If you have a Senville cassette-style air conditioning unit, the test mode process may differ slightly. In such cases, you may need to adjust the dip switches inside the unit to enter the test mode.
