Spare parts 12/24V Blower Speed Controller with External Sensor

Details

The Webasto Blower Speed Control Unit (Article Number: 3391288C) is a sophisticated electronic thermostat and fan controller designed to provide precise climate management for 12V and 24V marine and mobile heating systems. Engineered for use with Webasto heat exchangers such as the Madera, Florida, and BB series, this unit allows for both temperature-controlled automatic operation and a 5-step manual override. The integrated "Auto" function intelligently adjusts fan speeds to reach and maintain the desired cabin temperature as efficiently as possible, significantly enhancing comfort in campers, boats, and commercial vehicles. The kit is supplied as a comprehensive set including the main digital control element, a pulse-width modulation (PWM) electronic module for smooth speed transitions, and a 5-meter external temperature sensor. This external sensor is a critical component, allowing the system to monitor actual room temperature rather than the air temperature at the heater's inlet, ensuring much more accurate thermal regulation. Built with high-quality materials and featuring an upgraded heat sink for superior dissipation, this Italian-made controller is a reliable solution for managing a wide range of hot air blower boxes and heat matrices on the market.
