7. Close Access Panels: Once all wiring is secure and verified, close and secure the furnace access panel(s).
8. Herstel krag: Turn on the circuit breaker for the furnace, then turn on the main power switch for the furnace unit.

5. Bedryfsinstruksies

After successful installation and power restoration, the ICM Controls ICM280C board will initiate the furnace's normal operating sequence. The board is designed to automatically manage the furnace's functions based on thermostat calls for heat or fan operation.

• Aanvanklike kragopwekking: Upon first power-up, the board will perform a self-diagnostic check. Refer to your furnace's specific manual for expected diagnostic LED patterns (if applicable) during this phase.
• Normale werking: When the thermostat calls for heat, the control board will sequence the ignition process, monitor flame presence, and activate the circulating fan at the appropriate time. When the thermostat calls for fan-only operation, the board will activate the fan.
• Veiligheidskenmerke: The board continuously monitors various safety sensors within the furnace. If a fault is detected (e.g., overheating, flame failure), the board will shut down the furnace and typically display a diagnostic code via an LED.

6. Onderhoud

• Do not attempt to clean the board with liquids or abrasive materials.

7. Probleemoplossing

If your furnace is not operating correctly after installing the ICM280C board, consider the following troubleshooting steps. Always disconnect power before inspecting internal components.

• No Power to Furnace:
  • Check if the furnace power switch is ON.
  • Check if the circuit breaker for the furnace is tripped.
  • Verify all main power connections to the control board are secure.
• Furnace Not Igniting / No Heat:
  • Ensure the thermostat is set to "Heat" and the temperature is above the ambient room temperature.
  • Check for diagnostic fault codes displayed by an LED on the control board. Refer to your furnace's specific manual for the meaning of these codes.
  • Verify gas supply is on.
• Fan Not Operating Correctly:
  • If the fan runs continuously, check the thermostat setting (e.g., "Fan ON" instead of "Auto").
  • If the fan does not run when it should, check for diagnostic codes.
  • Ensure all fan motor wiring connections to the control board are secure.
• Algemene wanfunksie: If the board displays a persistent fault code or the furnace exhibits unusual behavior, it may indicate a more complex issue. In such cases, it is strongly recommended to contact a qualified HVAC technician for diagnosis and repair.
