Replacement control module for Bosch HT3-class heating appliances (GZT5‑II variant), intended for professional service and parts inventory; suitable as an OEM Bosch replacement to restore control functionality and maintain system integration when an HT3 control is exchanged. I was unable to locate product-specific technical documentation for part number 8737712407 on Bosch North America sites; Bosch spare-parts catalogs reference control units generally but did not return this exact part.
