4. Поставување и инсталација

The installation of the flue gas temperature sensor requires technical expertise. It is strongly recommended that this procedure be performed by a certified heating engineer.

1. Подготовка:
   • Ensure the boiler is completely shut down and isolated from the main power supply.
   • Allow the boiler and flue system to cool down to a safe temperature.
   • Gather necessary tools (e.g., screwdrivers, wrenches, multimeter).
2. Locate Existing Sensor (if applicable): Identify the current flue gas temperature sensor's location within the boiler's flue system. Refer to the boiler's specific service manual for precise location.
3. Отстранете го стариот сензор: Carefully disconnect the electrical wiring from the old sensor. Then, unmount the sensor from its housing. Be mindful of any seals or gaskets.
4. Инсталирајте нов сензор:
   • Insert the new Viessmann 7822767 sensor into the designated opening in the flue. Ensure it is seated correctly and securely.
   • If applicable, use new gaskets or sealing compounds as specified by the boiler manufacturer to ensure a gas-tight seal.
   • Secure the sensor in place using the appropriate fasteners.
5. Поврзете жици: Connect the sensor's electrical connector to the corresponding wiring harness in the boiler's control unit. Ensure connections are firm and correct according to the boiler's wiring diagram.
6. Проверки по инсталацијата:
   • Visually inspect all connections and mounting points for security.
   • Вратете го напојувањето на котелот.
   • Perform a functional test of the boiler, monitoring the flue gas temperature readings on the boiler's display or diagnostic tool to confirm correct operation of the new sensor.

5. Принципи на работа

The Viessmann Flue Gas Temperature Sensor (7822767) is a thermistor-type sensor designed to provide precise temperature readings of the exhaust gases leaving the boiler's combustion chamber. Its primary functions include:

• Combustion Efficiency Monitoring: By measuring flue gas temperature, the boiler's control system can optimize the combustion process, ensuring maximum energy efficiency and reduced emissions.
• Безбедносен прекин: In the event of excessively high flue gas temperatures, which could indicate a fault or blockage, the sensor provides a signal to the boiler's safety system to shut down operation, preventing potential damage or hazards.
• Дијагностика на системот: The sensor's readings are used by the boiler's diagnostic system to identify and report operational issues, aiding in troubleshooting and maintenance.

The sensor continuously transmits temperature data to the boiler's electronic control unit, which then processes this information to regulate boiler operation.

6. Одржување

Regular maintenance ensures the continued accuracy and reliability of the flue gas temperature sensor. It is recommended that these checks be performed annually by a qualified technician during routine boiler servicing.

• Визуелна инспекција: Check the sensor and its wiring for any signs of physical damage, corrosion, or loose connections.
• Чистење: Over time, soot or debris can accumulate on the sensor probe, affecting its accuracy. Carefully clean the probe using a soft brush or cloth. Ensure the boiler is cool and power is disconnected before cleaning.
• Проверка на отпор: A qualified technician can measure the sensor's electrical resistance at known temperatures using a multimeter and compare it against the manufacturer's specifications to verify its accuracy.
• Интегритет на печат: Verify that the seal around the sensor's mounting point is intact and free from leaks. Replace if necessary.
