Overview
These controllers allow management of multiple zones connected to a single indoor unit using a 2-wire remote controller system.
Function settings must be configured based on site layout, number of zones, and sensor usage to ensure accurate temperature control and damper operation.
1. Initial Setup (via Wired Remote Controller)
(Refer to pages 1–5 of the manual)
Before performing any configuration:
Confirm the indoor unit’s Room Temperature Sensor Switching is set to “Both” (unit and controller sensors active).
Initial setup includes:
Zone Temperature Sensor Selection
Assign sensors to each zone (Zone 1–8).
Access via Zone Setting → Zone Temp. Sensor Selection.
Zone Group Setting
Define up to 4 groups and allocate zones (1–8) within each.
Set Priority Sensors per group for accurate control.
Zone Name Setting
Label each zone for easier operation (e.g., “Living”, “Room A”).
Sensor Name Setting
Name sensors (Sensor 1–11) to match physical installation points.
2. Zone Function Settings
(Refer to pages 6–9 of the manual)
Access Path
Menu → Maintenance → Zone Function Setting
Setup Procedure
Select Function No.
Select Setting No.
Adjust the parameter, then press OK to confirm.
3. Function Setting List (Summary Table)
(Refer to page 7–8)
| Function | Function No. | Setting No. | Factory Default | Details / Notes |
|---|---|---|---|---|
| Primary Controller Sensor | 7 | 0 = Disable / 1 = Enable | 0 | Set to “Enable” if using remote sensor; indoor unit must be “Both”. |
| Secondary Controller Sensor | 8 | 0 = Disable / 1 = Enable | 0 | Same condition as primary. |
| Number of Outlets | 11–19 | 0–10 | 1 | Set per zone according to number of connected dampers. |
| Spring Return Damper | 20 | 0 = Not in use / 1 = In use | 0 | Set to “In use” when spring-return dampers installed. |
| Optional Sensor Connection | 31–38 | 0 = Not in use / 1 = In use | 0 | Up to 8 optional sensors supported. |
| Temp. Correction (Cooling) | 41–48 | 0–16 | 0 | Adjust based on calibration offset (+4.0°C to -4.0°C). |
| Temp. Correction (Heating) | 51–58 | 0–16 | 0 | Same range as cooling correction. |
4. Number of Outlets (Example Configuration)
(Refer to page 9 diagram)
| Zone | Function No. | Setting No. (Outlets) |
|---|---|---|
| Zone 1 | 11 | 4 |
| Zone 2 | 12 | 2 |
| Zone 3 | 13 | 1 |
| Zone 4 | 14 | 0 |
| Common | 19 | 1 |
Each setting corresponds to the number of dampers/outlets per zone. The system will proportion airflow and temperature control accordingly.

Technician Notes
Always complete all zone, group, and sensor associations before setting function numbers.
For accurate control, confirm indoor unit and controller sensors both enabled.
Document all Function and Setting Numbers on commissioning paperwork for future service reference.
