Sikkerhedsoplysninger

ADVARSEL: Improper installation, adjustment, alteration, service, or maintenance can cause property damage, personal injury, or death. Read and understand these instructions completely before proceeding.

• Afbryd altid strømmen til ovnen, før du installerer eller servicerer styrekortet.
• Sørg for, at alle ledningsforbindelser overholder lokale og nationale elektriske forskrifter.
• Only qualified personnel should attempt installation or service.
• Kontroller korrekt jordforbindelse af ovnsystemet.

Opsætning og installation

The ICM280 is designed as a direct replacement. Follow these steps for proper installation:

1. Strømafbrydelse: Sluk for al strøm til ovnen på hovedservicepanelet. Kontroller, at strømmen er slukket, ved hjælp af en voluminøseventil.tage meter.
2. Adgang til gammelt opslagstavle: Locate and open the furnace access panel to expose the existing control board.
3. Dokumentledningsføring: Before disconnecting any wires, take clear photographs of the existing wiring connections. Label each wire and its corresponding terminal on the old board. This step is crucial for correct re-installation.
4. Fjern gammelt bræt: Disconnect all wires and mounting screws securing the old control board. Carefully remove the old board.
5. Installer nyt kort: Position the ICM280 control board in the same location as the old board. Secure it with the appropriate mounting screws.
6. Tilslut ledninger: Refer to your documented wiring and photographs. Connect each wire to its corresponding terminal on the ICM280 board. Ensure all connections are secure and tight. Pay close attention to the terminal labels (e.g., L1, L2, G, Y, W, R, C, etc.).
7. Bekræft forbindelser: Double-check all wiring connections against your documentation and the wiring diagram (if available for your furnace model).
8. Luk panel: Replace the furnace access panel.
9. Gendan strøm: Genopret strømmen til ovnen ved hovedservicepanelet.

Key labels such as "STATUS," "TEST," "L1," "L2," "G," "Y," "W," "R," and "C" are visible, indicating connection points for furnace components and power supply.

Operation

After successful installation and power restoration, the ICM280 control board will initiate the furnace's normal operating sequence. The board manages various furnace functions, including:

• Tændingskontrol: Manages the ignition sequence for the main burner.
• Blower Motor Control: Activates and deactivates the indoor blower motor based on heating or cooling demands.
• Sikkerhedsovervågning: Monitors various safety limits and sensors to ensure safe operation and shut down the furnace if a fault is detected.
• Diagnostisk LED: Provides diagnostic codes via a flashing LED to assist in troubleshooting (refer to the Troubleshooting section).

The specific operational sequence is determined by the furnace manufacturer's design and the thermostat's commands.

Opretholdelse

The ICM280 control board itself requires no routine maintenance. However, regular maintenance of the overall furnace system is crucial for its longevity and efficient operation. This includes:

• Filterudskiftning: Replace or clean the furnace air filter regularly (monthly or as recommended by the furnace manufacturer).
• Årlig inspektion: Have a qualified HVAC technician perform an annual inspection and tune-up of your furnace.
• Renhed: Keep the area around the furnace clean and free of obstructions.

Before performing any maintenance on the furnace, always disconnect electrical power at the main service panel.

Fejlfinding

The ICM280 features a diagnostic LED (labeled "STATUS" on the board) that provides flash codes to indicate operational status or fault conditions. Consult your furnace's specific manual for a complete list of diagnostic codes, as these can vary by furnace model. Common indications include:

• Fast ON: Normal operation, no call for heat/cool.
• Langsom flash: Normal operation, call for heat/cool.
• Hurtig flash: Indicates a fault condition. The number of flashes typically corresponds to a specific error code.

Generelle fejlfindingstrin:

1. Ingen strøm: Check circuit breakers and furnace disconnect switch. Ensure the furnace door panel is properly closed, as many furnaces have a safety interlock switch.
2. Furnace Not Starting:
   • Verify thermostat settings are correct.
   • Check for diagnostic codes on the STATUS LED.
   • Inspect wiring connections on the control board for looseness or corrosion.
3. Blower Not Operating:
   • Ensure the thermostat is calling for fan operation.
   • Check for diagnostic codes.
   • Verify blower motor connections.
4. Intermitterende drift: This can often be caused by loose connections, faulty sensors, or intermittent power supply issues. Check all wiring and consult a qualified technician.

If you are unable to resolve an issue after following these steps, contact a qualified HVAC service technician.
