SAFETY PRECAUTIONS
1. 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.
2. Turn-Off the power supply to the unit and follow sound Lock Out & Tag Out procedures to ensure that power supply is not
re-energised accidentally.
3. This control interface is connected to the wall controller terminal block on the CMI board via screwed terminals and Cat5e UTP
(AWG24) Data Cable, with nominal voltage of 12VDC (+/- 10%).
4. Make sure that the unit installation complies with all 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.
5. WH&S rules and regulations must be observed and will take precedence during installation process.
6. Only use this Control Interface with an ActronAir air conditioner as described in this installation guide.
01. Specifications
• Voltage: 12VDC +/- 10% (LC7 controller connects directly to the CMI board)
• Operating conditions: -10 to 60OC, < 90% RH non-condensing
• Storage conditions: -20 to 70OC, < 90% RH non-condensing
• Data: Cat5e UTP (AWG24) Data Cable, Maximum Cable Length up to 100m
NOTE
Do not use ActronAir 4 Core Data Cable Part Numbers: 4070-003 / AMDC4 or Non Twisted Pair multi core cable.
02. Installation
1. Remove front cover, as shown
• Insert and gently twist screwdriver into the slot at the bottom
of the Control Interface. Do this procedure alternately
between the two slots until the front of the control separates
from the back cover.
• Use large enough flat blade screwdriver to fit into the slot in
order to avoid damaging the Control Interface.

2. Mount back cover to the wall
• Mount the back cover to the wall with screws (not supplied)
via screw holes. If required, the use of a plasterboard
mounting bracket (not supplied) is recommended to mount
the back cover to the wall.
• Ensure that the Control Interface back cover is aligned and
levelled on the wall before tightening the screws.

04. Auto Controller Assignment
Upon initial start up of the system, all connected LC7 controllers will display “C-0”. After 3 seconds, an auto-assignment
process will take place - for example, if 3 controllers had been connected to the CMI board (maximum number of
controllers connected), “C-1”, “C-2” and “C-3” would be assigned and displayed on the corresponding controller.
NOTE
If the C-0 display did not change, check the wiring between the controller and Indoor Unit Board.
This may be caused by:
• Loose or interchanged wire connection or (between Controller and Indoor Unit Board)
• No communication between the controller and Indoor Unit Board due to faulty cable
NOTE
In the case of disconnecting the “C-1” controller from the system, the other LC7 controllers will show an error code (E56 - No
main wall controller detected). To troubleshoot this error code:
• Troubleshoot “C-1” LC7 controller - check the wiring & connection of the controller. If E56 is still being displayed on “C-2”
and “C-3”, connect a replacement LC7 controller. During its first power on cycle, it will auto assign itself to the vacant
address.
05. Sensor Enabling/Disabling and Calibration
NOTE
For this example, Wall Control Sensor 1 will be calibrated to have an offset of 1.3
