Spare parts Webasto Air Top External Temp Sensor 2.5m Cable

Details

The Webasto External Temperature Sensor (Article Number: 9030881A) is a genuine replacement part designed for use with Webasto Air Top series air heaters, specifically the Air Top 2000, S, ST, STC, and the larger Air Top Evo 3900, 5500, 40, and 55 models. This high-precision sensor features a 2.5-meter cable, allowing it to be mounted away from the heater unit to monitor the actual room temperature of the living space rather than the temperature at the heater's air inlet. Using this sensor in conjunction with a rheostat or digital controller enables more accurate and efficient climate control, which is particularly beneficial in installations where the heater draws in fresh outdoor air. By providing the ECU with precise data from the cabin, it prevents overheating and ensures a consistent comfort level in boats, campers, and commercial vehicles. This kit is compatible with both 12V and 24V systems and is essential for resolving H94 interruption faults on modern digital controllers. EAN: 4054037111693. Predecessor article number: 9029776B.
