Safety and Operational Precautions
Safety Precautions
- Read all instructions in this manual before operating the air conditioning unit. Failure to do so may result in damage to the unit and void your warranty.
- Turn-Off power from mains supply by removing fuse or switching the circuit breaker to the "Off" position before installation or servicing this control interface.
- Follow sound Lock Out & Tag Out procedures to ensure that power supply is not re-energised accidentally.
- This control interface has power supply from the control board via telephone connector, with voltage of 18/30VDC protected by 250mAT external fuse & maximum power input of 0.8W. Ensure that this unit is not installed on voltages higher than 30V DC supply.
- Installation and/or servicing must be carried out by a qualified installer or technician.
- Ensure that the unit installation complies with relevant council regulations and building code standards. All electrical wiring must be in accordance with current electrical authority regulations and all wiring connections to be as per electrical diagram provided.
- WH&S rules and regulations must be observed and will take precedence during installation process.
- Only use this wall controller with an ActronAir air conditioner as described in this operating manual.
Operational Precautions
Access Panels and Guards: NEVER remove any access panels or guards as this could cause injury from electric shock and burns from extremely hot components. Never allow any bodily parts such as fingers or objects to protrude through the fan guards or any other opening as they could cause personal injury and damage the air conditioner.
Return Air Filter: The air conditioner must never be operated without a return air filter as this will allow a build up of dust or dirt on the indoor coil. This is very difficult to clean and can cause the system to operate inefficiently or even fail.
Crankcase Heater Precaution: The main power (switch board) to the system must be kept ON at all times to prevent damage to the outdoor compressor. Should the main power be disconnected or interrupted for 6 hours or longer, then no attempt should be made to start the system for 2 hours after the power has been restored to outdoor unit. This allows the compressor to warm up, and remove any liquid refrigerant that may cause damage.

Dual Control Operation (Mimic Logic)
The air conditioning system can be operated from either of two control interfaces. Information displayed on both interfaces is identical. The last control interface used has priority.
Example 1: If Control Interface #1 starts cooling, both interfaces show cooling mode. If Interface #2 then selects heating, both interfaces will show heating mode.
Example 2: If Interface #2 sets room temperature to 16.0°C, both interfaces display this. If Interface #1 changes it to 18.0°C, both will show 18.0°C and the system will operate at the new setpoint.

Maintenance
Maintenance Procedures
This section describes the specific maintenance procedures that must be performed as part of a normal maintenance program. Always disconnect electrical power to the unit before performing these procedures. It is always a safe practice to observe all safety warnings and cautions when conducting maintenance tasks.
DANGER: Live Electrical Connections! It may be necessary to work near live electrical components on certain maintenance tasks. Only licensed electricians and/or qualified technicians who are competently trained are allowed to perform service tasks.
WARNING: Hazardous Voltage! Always make sure that all power supplies, including remote controls, are isolated before performing maintenance. Observe proper Lock-Out / Tag-Out procedures to ensure that power cannot be inadvertently energised. Failure to isolate power before maintenance procedures can result in serious injury or death.
Periodic Maintenance Checkpoint
- Perform all monthly maintenance inspections.
- Inspect coil surfaces for cleanliness. Clean as required, apply cleaning procedures based on prevailing industry standard.
- Inspect unit air filters, clean or replace as required.
Annual Maintenance Checklists
- Perform general maintenance inspections.
- Perform scheduled start-up checks.
- Leak test refrigerant circuits.
- Inspect contacts of all contactors and relays. Replace all worn contacts as required.
- Inspect, clean and tighten all electrical connections.
- Check fans for balanced operation. Make sure that there are no loose screws/bolts, no fan blades interference and no damage to the fans and guards.
- Inspect unit air filters, clean or replace as required.
- Clean and repaint any corroded panel surface.
Cleaning the Control Interface
Wipe the control interface with a dry cloth. Do not use water or any other solvent-based solutions as it can cause damage to the outer case and electronic components of the controller.
Air Filter Maintenance
Regularly check the air filters for cleanliness or when a filter alarm is indicated on the control interface.
Cleaning the Condenser Coils
Clean the coils at least once a year or more frequently if the unit is located in a dusty and/or dirty environment, in order to maintain your system's proper operating performance. High discharge pressures are a good indication that the coils need cleaning. When using detergent or solvents to clean the coils, follow the manufacturer's instructions to avoid potential damage to the coils and to the unit.
To clean the refrigerant coils, use a soft brush and water spray, such as a garden hose or pressure washer with a low-pressure nozzle.
Outdoor Maintenance
Do not obstruct airflow to the outdoor coil to ensure your air conditioner operates efficiently. Use light detergent solutions to clean the surface of the panels. Repaint corroded panel surfaces, as required.
