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:

  1. single digit number (eg 9)
  2. the heat and cool indicators flashing simultaneously
  3. 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 CodesProblem
E1Outdoor coil sensor open or closed circuit
E2Fault indoor coil out sensor
E3Fault room sensor
E4Fault indoor coil sensor
E5Communication error between outdoor and indoor
E6Fault Discharge temperature
E7Fault outdoor coil sensor
E8Fault outdoor discharge sensor
E9High 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

Actron AC Troubleshooting

Conditions: The system does not start.

Remedy:

  • Check that 5 minutes has passed from the time you turned the system on as there are in-built safety timers.
  • Check thermostat settings are correct.
  • Check thermostat set point is low enough for cooling or high enough for heating.
  • Check the Master Controller is set to the correct mode for COOL/AUTO/HEAT.

Conditions: Air does not flow.

Remedy:

  • Check if the unit is set in the correct mode COOL/AUTO/HEAT.
  • Check your zone control is turned on. If using sensor ensure your zone is on at the master.
  • During defrost cycle of the outdoor unit in heating mode, the indoor fan will not operate. Defrost cycle is indicated when the heat LED on the master control is flashing.

Conditions: OFF is displayed on my zone control and I can not turn it on.

Remedy: This means the Master Controller is turned off. First turn on your air conditioner at the master control. You will now be able to turn on your zone control.

 

Frequently Asked Questions

1- I can not adjust my set point on my zone controller any more than 2 degrees higher or lower than the master controller.

-2 degrees is the the default setting for master temperature offset. ActronAir recommend this 2 degree offset to optimise temperature control and maximize energy efficiency. Moving this settings outside +/-2 degrees will result in temperature inaccuracy

2- Cooling and Heating seems to take a long time to achieve temperature in ESP fan mode. Am I using the correct settings?

-ESP fan mode really comes into it’s own when minimal zones are used. For quicker and more responsive Cooling and Heating when using more than minimal zones, select High or Cont High fan speed on the master control. This will boost heating and cooling and is best optimized when you want to condition more than the minimal zone set up.

3- Cooling and Heating is not sufficient in my zone.

-Air balancing is essential part of system commissioning in Ultima system. The duct design may be prohibiting the correct amount of airflow reaching your area. Please contact your installer to ensure air balancing has been carried out.

4– There is substantial air noise coming from my outlet.

-If the outlet gets too noisy when the unit or zone is first turned on, the system maybe over supplying airflow to your area. Ensure ESP fan mode is used when using minimal zones.Please contact your installer to ensure air balancing has been carried out.

5- There are dashes across my control display

-Make sure you have not had a power cut out. If this is still present on the display after 20 seconds, please contact your installer. Incorrect wiring or a broken circuit could also cause these symptoms
