Bosch Greentherm Control Unit (PN 87387027220) is an OEM replacement control module for Bosch Greentherm tankless gas water heaters, providing core electronic control and diagnostic functions to restore factory operation. Designed for contractors and wholesale parts channels, it restores factory control logic and enables straightforward troubleshooting. I could not locate PN 87387027220 on Bosch North America product or parts pages; this description is therefore based on Greentherm control‑module category information. (bosch-homecomfort.com)
