General Troubleshooting Steps:

1. No Power/Display Off:
   • Check the main power supply to the air conditioning unit.
   • Ensure the control panel is securely connected to its wiring.
   • Verify circuit breakers are not tripped.
2. Buttons Unresponsive:
   • Ensure the panel is receiving power.
   • If a specific button is stuck, gently try to free it.
   • A power cycle (turn off power at breaker, wait 30 seconds, turn back on) may resolve temporary glitches.
3. Incorrect Temperature Reading:
   • Check for F** error code, indicating a sensor malfunction.
   • Ensure the control panel is not exposed to direct heat sources or drafts that could affect its internal temperature sensor.
