Vaillant Boiler Flow Sensor Card (178988)
The Vaillant Boiler Flow Sensor Card (Part Number: 178988) is a high-grade electronic monitoring component designed to handle the demanding heating and hot water cycles within specific Vaillant domestic boilers. Engineered to track real-time flow rates, this sensor card provides perfectly accurate data transmission to the main printed circuit board (PCB). It prevents internal pressure drops, improper burner firing, and heating imbalances between the central heating circuit and domestic hot water supply.
High Operational Stability: Engineered from premium electronic components that monitor and report hydraulic flow shifts reliably under continuous high-temperature demands without weakening or losing calibration.
Fault & Delay Prevention: Directly eliminates erratic hot water delivery and system ignition failures that occur when original sensor chips degrade or fail over time.
Flawless Plug-and-Play Seating: Dimensioned precisely to lock cleanly into the flow sensor housing tracks, reducing the risk of wiring distortion or contact shifting during tightening.
