Thermal Resistance: Specifically engineered insulation prevents melting or grounding out when routed past hot furnace components

Viessmann 7819967 Sensor 322055-301 This is an integrated controlThe 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
