Unit Features

Auto-Restart After Power Failure| If the unit loses power, it will automatically restart with prior settings, once power has been restored.
---|---
Multiple Wall Controller Operation (Optional)| Up to three wall controllers can be installed on one system. This is particularly useful for larger houses, where you can have controls in different locations or if multiple sensing points are required.


Room Temp Display with One Touch

| Simply press SELECT UP or DOWN button and the set temperature display will change to show the room temperature for 3 seconds.

Note: When zone sensors are fitted, the temperature displayed will depend on which sensor has been selected by the wall controller (only applicable to LR7 and LC7-2).


Sense More Technology

| Sense More technology means ActronAir systems come with more temperature sensing points, which allows them to evenly maintain the temperature throughout your home no matter the time of day.


Auto Defrost Function (HEATING Mode)

| At certain outdoor conditions (low temperature) frost may build up on the outdoor heat exchanger. This gradual build up of frost reduces the performance of the air conditioner. The microprocessor detects this frost build up and will automatically activate the DEFROST mode. The DEFROST mode is displayed on the wall controller by flashing the HEAT symbol every 10 seconds.
Hot Start Function (HEATING Mode)| When the air conditioner starts in HEATING mode, the indoor fan is delayed for a short period of time, this allows the heat exchanger to warm up before the air starts to flow, thus preventing excessive cold drafts. The hot start feature also activates itself when the system finishes a defrost cycle.


Filter Clean Light

| The microprocessor monitors the accumulated run time of the air conditioner and after a preset number of hours has passed, the FILTER light will flash, indicating it is time to check if the filter needs cleaning.

Note: Only applicable to ActronAir wall controllers.

Self Diagnosis| 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.

NOTE

Refer to individual wall controller owner’s manuals for a full list of features.

Tips on Using the Air Condition

Operating Tips for Summer

It is recommended to test run your air conditioner a few weeks before the start of summer and make sure it is cooling sufficiently. If the air conditioner needs servicing, we advise you to have this done before the summer season arrives.

A hot day is forecast for tomorrow, what should you do?

Always start the air conditioner early in the morning and keep the house/office cool. If you try and start the air conditioner in the afternoon when the house/office is already very hot, it may take a while to cool down. Keep all curtains and windows closed. Also stop drafts coming in from outside.

If zones have been installed you should turn off any zone that is not being occupied. This will allow higher cooling capacity for the occupied areas.

Ask your installer for any zoning limitations for your system.

NOTE

Always allow the necessary amount of fresh air into rooms.

Operating Tips for Winter

It is recommended to test run your air conditioner a few weeks before the start of winter and make sure it is heating sufficiently. If the air conditioner needs servicing, it is advised you have this done before the winter season arrives.

A cold day is forecast for tomorrow, what should you do?

You can leave the air conditioner running overnight, but lower the set point 2-4oC from your normal setting to help reduce power consumption. This will assist the house/office from becoming too cold overnight and thus enabling the air conditioner to warm the house/office quicker when you raise the temperature set point back to your usual setting.
OR
Start the air conditioner a couple of hours earlier than you normally would in the morning. If outside conditions are very cold (approximately 7oC or lower) supplementary heating may be used such as electric or gas heaters to complement and speed the heating up. This can be done by setting an ON timer prior to going to bed.

Keep all curtains and windows closed. Also stop drafts coming in from outside. When operating your system overnight or when the home/office is unoccupied, it is recommended on heating mode to turn the wall controller temperature down by 2-4oC. Alternatively when operating your system in cooling mode to turn the wall controller temperature up by 2-4oC.
This will help to reduce power consumption.

Ask your installer for any zoning limitations for your system.

NOTE

Always allow the necessary amount of fresh air into rooms.

Energy Conservation Tips

For the most efficient operation, keep the windows and doors closed including unused areas where possible. This approach not only helps to insulate against heat and cold, it also reduces dust, pollen and noise. Occasionally allow fresh air into rooms and offices that are closed off. When operating your system overnight or when the home/office is unoccupied it is recommended in heating mode to turn the wall controller temperature down by 2-4oC. Alternatively when operating your system in cooling mode to turn the wall controller temperature up by 2-4oC. This will help to reduce power consumption.

The normal wall controller setting recommended is 22oC for summer and winter.

By raising the set point by 1oC in summer or lowering the set point by 1oC in winter, you can save approximately 10% on electricity costs.

If your air conditioner has zones fitted, always turn off the zoned areas that are unoccupied.

Care and Maintenan

Wall Controller
Wipe the controller with a dry cloth. Do not use water.

Outlets and Return Air
Dust off the outlets and return air. Do this regularly to prevent the build up of dust or dirt.

Air Filter Cleaning
Clean every 12 weeks or when the filter light is displayed on your wall controller.

NOTE

In dusty environments the filter may require more regular cleaning.

  1. Turn the air conditioner off from the wall controller.
  2. Open the inlet grille. Be cautious, dust may fall from return air grille.
  3. Remove the filter by sliding it from the grille.
  4. Clean the filter by using a dust pan brush to remove the dust or wash the filter with water. Be gentle when cleaning the filter to avoid tearing of the filter material.
  5. Re-install the filter.

NOTE

  • When the filter light is flashing, check the air filter and clean if necessary and press the ON/OFF button to extinguish filter light.
  • Always check with your installer for the proper care and maintenance of the filter system.
  • Do not obstruct airflow.
  • Keep grass or plants away from the unit. This will ensure that your air conditioner operates efficiently.
  • It is recommended to have your filter material changed every 12 months on the annual maintenance.

Air conditioner not in use for long periods of time (eg. 2-4 weeks)

Power is used even when the system is not operating. The air conditioner should be switched off from the main circuit breaker when it is not being used for long periods of time, for example, when going on holidays etc. If the system is  switched off for greater than 8 hours, it is recommended to not turn the system back from the wall controller for a minimum of two hours after the main circuit breaker is turned on.

NOTE

All general maintenance and care of systems should be undertaken by a licensed technician.

Troubleshooting

SAFETY PRECAUTIONS

If ANY of the following conditions occurs, turn off your unit immediately!

  • You smell a burning odor
  • The unit emits loud or abnormal sounds
  • A power fuse blows or the circuit breaker frequently trips
  • Water or other objects fall into or out of the unit

DO NOT ATTEMPT TO FIX THESE YOURSELF! CONTACT Authorised SERVICE PROVIDER IMMEDIATELY!

The following problems are not a malfunction and in most situations will not require repairs.

Fault Possible Causes
Unit does not turn on when pressing ON/OFF button

Check that 5 minutes has passed from turn on time, as the system has inbuilt safety timers.

•      Check if thermostat settings are correct.

•      Check the thermostat set point is set low enough for cooling or high enough for heating.

Outdoor units emit mist| •      When the unit restarts in HEAT mode after defrosting, mist may be emitted due to moisture generated from the defrosting process.
The unit makes noises| •      Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.

•      Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction.

•      When the unit starts, the outdoor unit may be louder than normal for a few seconds, whilst the compressor reaches the designated speed and operation pressures.

The outdoor unit makes noises| •      The unit will make different sounds based on its current operating mode.
Dust is emitted from either the indoor or outdoor unit| •      The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.
The unit emits a bad odor| •      The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations.

•      The unit’s filter have become moldy and should be cleaned.

•      The indoor drain line P-trap may have dried out.

The fan of the outdoor unit does not operate| •      The indoor room temperature has reached the set temperature. During operation, the fan speed is controlled to optimize product operation.
Air does no flow from the indoor unit| •      Check Zones are switched on.

•      During heating operation, air does not flow for approximately 15 seconds after start up or during defrost, this reduces cold drafts.

Cooling/Heating is not sufficient| •      Return Air Filter is clogged with dust and dirt.

•      Air inlet and air outlet on the outdoor unit are blocked.

•      Outside temperature is above or below the design conditions.
