Mounting the Controller

Detailed steps for wall mounting.

1. Turn off power to the indoor unit(s).
2. Remove the front cover of the controller by gently prying it off.
3. Use the mounting bracket to mark the positions of the mounting holes on the wall.
4. Drill holes and insert wall plugs if necessary.
5. Secure the mounting bracket to the wall using the provided screws.
6. Route the communication/power cables through the cable entry hole in the bracket.
7. Connect the wires to the terminal block on the back of the controller (see Wiring section).
8. Snap the controller onto the mounted bracket until it clicks into place.
9. Replace the front cover.

Tip: Ensure the controller is level before final tightening of screws.

Wiring Connections

Refer to the specific wiring diagram for your indoor unit model.

1. Identify Terminals: Locate terminals marked for Communication (e.g., A, B or 1, 2) and Power (e.g., +12V, GND).
2. Prepare Wires: Strip approximately 10mm of insulation from the wire ends.
3. Connect to Controller: Insert wires into the corresponding screw terminals on the controller backplate and tighten securely.
4. Connect to Indoor Unit: Connect the other ends to the designated terminals on the indoor unit's PCB or terminal block.
5. Check Polarity: For communication wires, ensure correct polarity (A to A, B to B).

WARNING! Do not connect communication wires to power lines. Use shielded cable for long runs and ground the shield at one end only.

Initial Setup & Configuration

After wiring and power restoration, configure the controller.

1. Power On: Turn on the main power. The controller display should light up.
2. Address Setting (if required): For multi-system control, set the controller address via DIP switches or software settings as per system manual.
3. System Check: Press the ON/OFF button. The connected indoor unit should respond (fan may start).
4. Test Basic Functions: Test mode change (Cool, Heat), temperature adjustment, and fan speed control.
5. Configure Clock & Timer: Set the current time and configure any desired timer programs.

Note: Some settings may require access to the installer settings menu (see Advanced Settings).

Basic Operation

Guide to daily use.

1. Power: Press ON/OFF to turn the connected system on or off.
2. Mode Selection: Press MODE to cycle through Auto, Cool, Heat, Dry, Fan.
3. Temperature: Use ▲/▼ buttons to set desired room temperature.
4. Fan Speed: Press FAN button to cycle through speed options.
5. Timer: Press TIMER button to set On or Off timers.
6. Filter Reset: Press and hold FILTER button for 3 seconds to reset the filter maintenance indicator after cleaning.

Tip: In Auto mode, the system automatically selects Cool or Heat based on room temperature.

Advanced Settings

Access installer settings for system configuration. (Typically requires a specific button combination on power-up).

Common advanced settings include:

• Temperature Unit: °C or °F.
• Key Beep: Enable/disable button sound.
• Backlight Duration: Set display backlight time.
• System Configuration: Assign controller to specific indoor units in a multi-system setup.
• Function Lock: Restrict user access to certain settings.

CAUTION! Incorrect advanced settings may affect system performance. Refer to the full system technical manual for details.

Maintenance & Care

Unplug system power before any maintenance.

1. Cleaning: Wipe the front panel with a soft, dry cloth. Do not use abrasive cleaners or solvents.
2. Display: Clean LCD with a slightly damp cloth, then dry immediately.
3. Ventilation: Ensure no objects block the controller or its sensors.
4. Inspection: Periodically check wire connections for tightness and signs of corrosion.

CAUTION! Do not disassemble the controller. Internal servicing must be done by qualified personnel.

Troubleshooting

Reset: To reset to factory defaults, typically involves a specific button sequence (e.g., hold MODE and FAN during power-up). Refer to technical manual.

Service: For persistent issues, contact Daikin authorized service center. Have model and serial numbers ready.
