Viessmann 7819967 Sensor
The Viessmann 7819967 Sensor is a critical NTC thermistor engineered for precise temperature monitoring in Vitodens 200-W and Vitodens 100-W series condensing boilers. This dual-purpose component functions as either Sensor #3 for boiler water temperature or Sensor #5 for Domestic Hot Water (DHW) tank monitoring. Designed to provide high-accuracy resistance feedback to the Vitotronic control platform, it ensures the burner modulates correctly based on real-time thermal loads. The sensor features a robust brass housing for optimal heat transfer and integrated lead wires with a proprietary plug-and-play connector to prevent wiring errors during field replacements. Technicians should verify ohm readings against the standard Viessmann temperature-resistance curve to diagnose F2 or F4 faults. Proper seating within the dry well is essential to prevent thermal lag and maintain the energy efficiency of the hydronic system while ensuring consistent DHW setpoints.
Technical Features and Benefits- Dual Application Compatibility: Designed for use as both the primary boiler temperature sensor and the indirect DHW tank sensor.
- High-Accuracy NTC Thermistor: Delivers precise resistance data to the control board for tight modulation and fuel efficiency.
- OEM Vitodens Integration: Direct replacement part ensures full communication with Vitotronic 200 and 300 series controls.
- Durable Construction: Built to withstand constant thermal cycling without drift in electrical resistance.
- Simplified Installation: Factory-terminated leads reduce labor time and ensure a secure, moisture-resistant connection.
Is the Viessmann 7819967 interchangeable with other boiler brands?
No, this sensor is calibrated specifically for the resistance curves required by Viessmann control logic. Using a generic sensor will result in inaccurate temperature readings and potential lockout codes.
What are the signs that a DHW sensor is failing?
Common symptoms include inconsistent hot water temperatures, the boiler failing to cycle for a DHW call, or specific Vitodens error codes indicating an open or shorted circuit at the #5 sensor terminal.
Does this sensor require a thermal paste during installation?
While not always required by the manual, applying a thin layer of high-quality thermal conductive paste can improve response time and accuracy by ensuring better contact with the immersion well.
