Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | Device not cooling on air conditioning system | The unit could be running its thawing cycle, or the temperature set on the remote has already been reached or is set too high. | Wait for thawing procedure to finish, or lower the temperature setting on the remote control. | DIY Safe |
N/A | Device not heating on air conditioning system | The unit could be running its thawing cycle (this happens between 4°C and 7°C outside), or the outside temperature has dropped below 4°C. | Let the thawing cycle finish if it's between 4°C and 7°C outside - below 4°C, heating performance drops off so much that the unit can't heat at all. | DIY Safe |

N/A | Moisture on underside of air distributor on air conditioning system | High air humidity at beginning of cooling procedure | Close all windows and doors and select high fan level. | DIY Safe |
N/A | Water dripping out of air distributor on air conditioning system | Could be a blocked condensation trap on the outside unit, a damaged roof seal, or the vehicle parked at too steep an angle. | Clear condensation trap on external unit, check seal between device and roof, or level the vehicle. | DIY Safe |
N/A | Remote control not working for air conditioning system | Empty or depleted batteries in remote control | Check batteries in remote control and replace if necessary. | DIY Safe |
N/A | Device not reacting to remote control commands on air conditioning system | Obstructions between remote control and IR receiver, or remote control not tuned to the IR receiver | Check for anything blocking the line of sight between the remote and the IR receiver, and re-tune the remote to the receiver. | DIY Safe |

Q: How do I tune the air conditioning remote control to the IR receiver?
Fit the batteries the right way round (the setup symbol will flash). Point the remote at the IR receiver and hold the Setup button down - once the receiver's red LED starts flashing, let go of the button.
Q: How do I reset the remote control settings to factory defaults?
Press the reset button on the remote control using a ballpoint pen.
