REF: 4377
Product Description:
The Autoterm Flow 5B 12V Electronic Control Unit (ECU) is specially designed for Autoterm Flow 5B gasoline water heaters. Compatible with all Autoterm Flow 5B 12V water heaters bearing the serial number 482100XXXXX, this unit ensures optimal operation of your system. For Pierburg and Bosch PAD liquid pumps, a specific wiring harness is required (4366 for Pierburg, 4044 for Bosch PAD). If this control unit replaces a Binar 5S 12V water heater, it is also necessary to replace the wiring harness to ensure compatibility with the Pierburg pump. Optimize the performance of your heater with this reliable and durable control unit.
