LC7-2G Wall Control
Product Information: Wall Control
The Wall Control is a device that allows you to control your
ActronAir air conditioning unit. It comes in two models: LC7-2W and
LC7-2G. The control interface is connected to the wall control
terminal block on the Indoor board via screwed terminals and Cat5e
UTP (AWG24) Data Cable. It is important to follow the safety
precautions and installation guide provided in the manual before
operating the air conditioning unit.
Specifications
Do not use ActronAir 4 Core Data Cable Part Numbers: 4070-003 /
AMDC4 or Non-Twisted Pair multi core cable.
Installation
The installation process involves the following steps:
- Read all instructions in the manual before operating the air
conditioning unit. Failure to do so may result in damage to the
unit and void your warranty. - Turn off the power supply to the unit and follow necessary
LOCK-OUT / TAG-OUT (LOTO) procedures to ensure that power supply is
not re-energised accidentally. - Ensure that this unit is not installed on voltages other than
specified. - 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 must follow the electrical
diagram provided. - WH&S rules and regulations must be observed and will take
precedence during installation process. - Only use this Control Interface with an ActronAir air
conditioner as described in this installation guide. - Remove back cover, mount back cover to the wall, and the bottom
of the Control Interface. Do this procedure alternately between the
four slots until the back cover of the plasterboard mounting
bracket (not supplied) is recommended to mount the back cover to
the wall. Make sure that the Control Interface is centered and
leveled on the wall before tightening the screws. - Wire the Wall Control in accordance with the provided wiring
diagram. - Select zone buttons.
- Attach the front cover. Ensure protective film is removed from
inside of the front cover before attaching. Front cover can be
removed even after installation. Press at the bottom of the control
interface and pull the front cover.

05. Controller Assignment
NOTE
For installations where an LC7-2 is being installed with a Neo Wall Control, C-1 will always need to be assigned to the Neo Wall Control.
Upon initial start up of the system, all connected LC7-2 controls (up to 3) will display C-0. After 3 seconds, an auto-
assignment process will take place with the auto-assigned control ID displayed on the screen C-1, C-2 and C-3. The user
can change the control assignment between C-1 and C-3 with the
or buttons. For the system to function
correctly, a C-1 control must be present, with each control requiring a unique control assignment. The displayed text will
remain on the control until user acknowledges the assignment by pressing the PROG button to enter the Home Screen.
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
Upon subsequent power cycles, all controls will show their control ID for 3 seconds before proceeding to the home screen.
Manual Control Assignment

5. Press the EXIT button once to return to Main Screen.
NOTE
In the case of disconnecting the C-1 control from the system, the other LC7-2 controls will show an error code (E56 – No main wall control detected). To troubleshoot this error code:
· Troubleshoot C-1 LC7-2 control – check the wiring and connection of the control. If E56 is still being displayed on C-2 and C-3, connect a replacement LC7-2 control. During its first power on cycle, it will auto assign itself to the vacant address.
06. Sensor Enable/Calibration
1. Press and hold the REPEAT and TIMER buttons for 3 seconds then release to enter Service Menu. 2. Press the button to scroll through to Service Menu 02. 3. Press the PROG button to enter Service Menu 02.

4. Press the
or buttons to select the appropriate sensor to calibrate or turn ON or OFF.
5. Press the PROG button to enter Wall Control Sensor settings.
