ആമുഖം
This manual provides instructions for the installation, operation, and maintenance of the ICM Controls ICM289 Furnace Control Board. The ICM289 is designed as a direct replacement for Lennox BCC1, BCC2, and BCC3 series circuit boards, offering form, fit, and functional compatibility. This microprocessor-based control board manages the inducer fan motor, blower fan, and monitors limit switches, ensuring proper furnace operation. It is compatible with all 24 VAC thermostats.
സുരക്ഷാ വിവരങ്ങൾ
മുന്നറിയിപ്പ്: Before attempting any installation, maintenance, or troubleshooting, ensure that the main power supply to the furnace is disconnected at the circuit breaker or fuse box. Failure to do so can result in electrical shock, personal injury, or death. Installation should only be performed by qualified personnel. Always wear appropriate personal protective equipment.
- Disconnect all power to the furnace before servicing.
- വൈദ്യുതി പുനഃസ്ഥാപിക്കുന്നതിന് മുമ്പ് എല്ലാ വയറിംഗ് കണക്ഷനുകളും സുരക്ഷിതവും കൃത്യവുമാണെന്ന് ഉറപ്പാക്കുക.
- സുരക്ഷാ ഉപകരണങ്ങളെ മറികടക്കരുത്.
സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
The ICM289 board is designed for straightforward replacement of existing Lennox BCC1, BCC2, and BCC3 control boards. Follow these steps carefully:
- വൈദ്യുതി വിച്ഛേദിക്കൽ: Ensure all electrical power to the furnace is completely disconnected.
- ഡോക്യുമെൻ്റേഷൻ: Before removing any wires, take clear photographs of the existing control board and its wiring connections. Label each wire precisely as it connects to the old board. This documentation is crucial for correct re-installation.
- Old Board Removal: Carefully disconnect all wires from the old control board. Unmount the old board from the furnace chassis.
- New Board Mounting: Position the ICM289 replacement board. It features plastic clip-spacers designed to align with the mounting holes used by the original BCC3 boards. Secure the new board in place. The rear PCB of the ICM289 has a protective coating to prevent arcing to the metal mounting surface.
- വയറിംഗ് കണക്ഷൻ: Refer to your photographs and labels. Connect each wire from the furnace to its corresponding terminal on the ICM289 board. While most connections are identical, if an adapter is provided for a specific terminal, ensure it is used correctly. Verify all connections are firm and correctly seated.
- വൈദ്യുതി പുനഃസ്ഥാപിക്കൽ: Once all connections are verified, restore power to the furnace.
- പ്രാരംഭ പരിശോധന: Initiate a heating cycle to confirm proper operation of the furnace, including the inducer fan, igniter, burners, and blower fan.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ
The ICM289 furnace control board operates automatically in conjunction with your 24 VAC thermostat. Once installed and power is restored, the board will manage the furnace's heating and cooling cycles based on thermostat demands.
- ചൂടാക്കൽ ചക്രം: Upon a call for heat from the thermostat, the board initiates the inducer fan, verifies safety switches, activates the igniter, opens the gas valve, and then engages the blower fan once the heat exchanger is sufficiently warm.
- തണുപ്പിക്കൽ ചക്രം: Upon a call for cool, the board activates the blower fan to circulate air through the cooling coil.
- ഫാൻ പ്രവർത്തനം: The board controls the blower fan for both heating and cooling, as well as continuous fan operation if selected on the thermostat.
മെയിൻ്റനൻസ്
Regular maintenance of your furnace system is essential for the longevity and proper functioning of the control board and the entire unit. While the control board itself requires no direct user maintenance, certain system conditions can impact its performance and lifespan.
- വായുപ്രവാഹ നിയന്ത്രണം: Ensure proper airflow through your furnace. Restricted airflow can cause the blower fan to work harder, potentially leading to overheating of the control board components. Regularly check and replace air filters.
- വെൻ്റിലേഷൻ: Keep all supply and return air vents open and unobstructed. Closed vents can contribute to restricted airflow.
- AC Condenser: If applicable, ensure your outdoor AC condenser coil is clean and free of debris to maintain efficient system operation.
- പ്രൊഫഷണൽ പരിശോധന: Schedule annual professional inspections of your furnace system to identify and address potential issues before they lead to component failure.
ട്രബിൾഷൂട്ടിംഗ്
If your furnace is not operating correctly after installing the ICM289 board, consider the following troubleshooting steps:
- ശക്തിയില്ല:
- Check the circuit breaker or fuse for the furnace.
- ഫർണസ് പവർ സ്വിച്ച് "ഓൺ" സ്ഥാനത്താണെന്ന് ഉറപ്പാക്കുക.
- എല്ലാ ലോ-വോളിയം ഉം പരിശോധിച്ചുറപ്പിക്കുകtage thermostat wires are securely connected.
- Furnace Not Heating:
- Confirm the thermostat is set to "HEAT" and the temperature is above the ambient room temperature.
- Check for any error codes on the control board (refer to furnace manufacturer's documentation for code interpretation).
- Ensure the gas supply valve to the furnace is open.
- Blower Fan Not Operating Correctly (e.g., not turning on, not shutting off):
- Re-verify all blower motor wiring connections to the control board.
- Check for any obstructions in the blower assembly or ductwork.
- Ensure the thermostat fan setting is correct (AUTO vs. ON).
- ഇടയ്ക്കിടെയുള്ള പ്രവർത്തനം:
- Inspect all wiring for loose connections or signs of damage.
- Ensure limit switches and other safety devices are functioning correctly (consult a professional).
