Installation
-
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. -
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 mountthe back cover to the wall.
• Ensure that the Control Interface back cover is aligned and levelled on the wall before tightening the screws.
-
Connect wiring at the back of Control Interface
• Ensure that all wiring is tightly connected. All wiring must be in accordance with the provided wiring diagram.

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.
Sensor Enabling/Disabling and Calibration
NOTE
For this example, Wall Control Sensor 1 will be calibrated to have an offset
of 1.3
-
Press and hold the “REPEAT/ “ and “ ¸ TIMER” Buttons for 3 seconds then release to enter Service Menu.
-
Press the “SELECT Button to scroll through to Service Menu 02.
-
Press the “PROGRAM” Button to enter Service Menu 02.
NOTE
The display will toggle between sensor name (“CS1” – Wall Control Sensor 1) and the existing calibrated offset. By default, all connected sensors are “ON” and have a calibration factor of 0. CS1/CS2/CS3 represent wall controller sensors rS1/rS2 represents remote sensors -
Press the “SELECT ” Button to select the appropriate sensor to enable/disable and calibrate.
-
Press the “PROGRAM“ Button to enter Wall Control Sensor 1 settings.
-
Press the “SELECT ” Button to change the temperature offset of Wall control sensor 1 (CS1) to 1.3.
Offset range is ±9.9, with 0.1 increments per “SELECT Button press.
The “ON/OFF” Button may be pressed to enable / disable sensor. -
Press the “PROGRAM“ Button to accept the temperature offset of Wall Control Sensor 1.
-
Repeat steps 4-7 to enable / disable and calibrate other applicable sensors.
-
Press the “EXIT“ Button twice to return to Main Screen.
