4. Attach PCB casing to the back cover
   • Attach the PCB casing by aligning with the back cover mounted on the wall.
   • Ensure the PCB casing makes a ‘click’ sound after mounting.

5. Select zone buttons
   • Remove the relevant zone buttons for zone name to be allocated and attach to wall control.
   • Ensure the buttons make a ‘click’ sound when attached to the PCB casing.
   NOTE
   Front cover can be removed even after installation. Press at the bottom of the control interface and pull the front cover.

**Controller Assignment

**

NOTE
For installations where an LR7 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 LR7 controls (up to 3) will display C-0. After 3 seconds, an auto assignment process will take place with the auto-assigned controller ID displayed on the screen C-1, C-2 and C-3. The user can change the controller assignment between C-1 and C-3 with the buttons. For the system to function correctly, a C-1 controller must be present, with each controller requiring a unique controller assignment. The displayed text will remain on the controller 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 controllers will show their controller ID for 3 seconds before proceeding to the Home Screen.

Manual Controller Assignment

1. Press and hold the REPEAT and TIMER buttons for 3 seconds then release to enter Service Menu.
2.  Press the PROG button to enter Service Menu 01.
3.  Press the buttons to select the appropriate controller assignment.
4.  Press the PROG button to accept the selection.
5.  Press the EXIT button once to return to Main Screen.

NOTE
In the case of disconnecting the C-1 controller from the system, the other LR7 controllers will show an error code (E56 – No main wall controller detected). To troubleshoot this error code:

• Troubleshoot C-1 LR7 controller – check the wiring & connection of the controller. If E56 is still being displayed on C-2 and C-3, connect a replacement LR7 controller. During its first power on cycle, it will auto assign itself to the vacant address.

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.
   NOTE
   The display will toggle between sensor name (CS1 – Wall Control Sensor 1) and actual temperature reading.
   By default, all connected sensors are enabled, displayed ON, and have a calibration factor of 0.
   CS1/CS2/CS3 represent wall controller sensors and rS represents remote sensor.

4. Press the buttons to select the appropriate sensor to calibrate or turn ON or OFF.
