مستشعر الماء الساخن المنزلي S3 رقم القطعة الإلكترونية 9

Hot water sensor S3 (electrical part pos. 9) monitors the water temperature in the DHW circuit, transmitting a signal to the boiler control board. This spare part for burners and boilers is necessary to maintain the set hot water temperature. The S3 sensor ensures measurement accuracy and stable system operation. If the sensor fails, temperature fluctuations or boiler shutdown may occur, so timely replacement of this part is important for comfortable hot water supply.
