Actron AC Error Codes and Troubleshooting
Actron AC Error Codes and Troubleshooting
In the unlikely event that a fault develops with the Air Conditioner the microprocessor will diagnose the fault (where possible) and display a fault code on the wall controller. The 7 Day Controller will display a code beginning with E (Eg E2) The 24 Hr Controller will display:
- single digit number (eg 9)
- the heat and cool indicators flashing simultaneously
- both codes showing together
Take note of the fault code and contact your installer. This code will indicate to the installer/repairer what the problem may be.
| Error Codes | Problem |
|---|---|
| E1 | Outdoor coil sensor open or closed circuit |
| E2 | Fault indoor coil out sensor |
| E3 | Fault room sensor |
| E4 | Fault indoor coil sensor |
| E5 | Communication error between outdoor and indoor |
| E6 | Fault Discharge temperature |
| E7 | Fault outdoor coil sensor |
| E8 | Fault outdoor discharge sensor |
| E9 | High or Low Pressure/Phase error |
E3: System has detected less than 2 sensor ( Ultima requires at least 2 sensors in circuit) or, a remote sensor is short circuit.
E5: No Communication. The system is constantly relaying information back and forth. This indicates the communication is not happening. Contact your installer to check your wiring and cable’s integrity
