8. Ustawienia początkowe: Some control boards may have adjustable potentiometers (blue components in Figure 2) or DIP switches (red component labeled SW3 in Figure 3) for initial calibration or model-specific settings. Consult your stove's specific manual for correct settings for your PF100 or PF120 model.
9. Wymień panel: Once all connections are secure and settings are confirmed, replace any service panels removed earlier.
10. Przywróć zasilanie: Restore power to the pellet stove by plugging it in or turning on the circuit breaker.
11. Operacja testowa: Follow your stove's normal startup procedure to ensure the new control board is functioning correctly.

Zasady działania

The Harman PF100 & PF120 Control Board is the central processing unit for your pellet stove. It receives input from various sensors (e.g., temperature, vacuum) and user controls, then outputs signals to manage components such as the auger motor, combustion blower, convection blower, and igniter. It regulates fuel feed rate and air supply to maintain desired heat output and efficient combustion.

While the board itself does not have direct user controls beyond initial setup adjustments, its proper function is essential for the stove's automated operation, including startup, shutdown, and temperature regulation. Any changes to the stove's performance should first be addressed by consulting your stove's user manual for operational adjustments, and then by troubleshooting the control board if issues persist.

Konserwacja

The Harman PF100 & PF120 Control Board is designed for long-term reliability and typically requires minimal maintenance. However, adhering to general electronic component care can extend its lifespan:

• Utrzymywać w suchości: Ensure the area around the control board remains dry and free from moisture, which can cause short circuits and corrosion.
• Usuwanie kurzu: Periodically, with power disconnected, gently remove any accumulated dust from the board using compressed air or a soft, dry brush. Avoid using liquids or abrasive materials.
• Bezpieczne połączenia: During routine stove maintenance, visually inspect all wire connections to the control board to ensure they remain tight and free from corrosion.
• Kontrola środowiska: Operate the stove within its specified environmental conditions to prevent extreme temperatures or humidity from affecting the board.

Rozwiązywanie problemów

If your Harman PF100 or PF120 pellet stove experiences operational issues, the control board may be a contributing factor. Before assuming the board is faulty, ensure all other components and connections are in good working order.

Common Symptoms of a Potentially Faulty Control Board:

• Stove fails to ignite despite a working igniter.
• Auger motor does not feed pellets, or feeds erratically.
• Blowers (combustion or convection) do not operate, or operate at incorrect speeds.
• Inconsistent temperature regulation.
• Error codes displayed on the stove's control panel that point to a general system failure.
• No power to the stove's control panel, even with power supply confirmed.

Kroki rozwiązywania problemów:

1. Sprawdź moc: Ensure the stove is receiving adequate power and the circuit breaker has not tripped.
2. Sprawdź połączenia: With power disconnected, inspect all wire connections to the control board for looseness, corrosion, or damage.
3. Sprawdź bezpieczniki: The control board may have onboard fuses (visible in Figure 2). With power disconnected, check these fuses for continuity using a multimeter. Replace any blown fuses with the correct type and rating.
4. Kontrola czujnika: Ensure all sensors connected to the board (e.g., exhaust temperature sensor, vacuum switch) are clean, properly connected, and functioning according to your stove's service manual.
5. Component Isolation: If possible, test individual components (motors, igniter) directly to rule them out as the source of the problem.
6. Diagnoza profesjonalna: If basic troubleshooting does not resolve the issue, it is recommended to consult a qualified Harman service technician for diagnosis and repair or replacement of the control board.
