The ICM Cascade Module is an accessory control for Bosch Greenstar boilers that coordinates multiple wall‑hung units in a cascade, enabling staged sequencing and centralized fault management to meet higher load demands. Designed for use with Greenstar Wall series (including ZWB and ZBR model families), it simplifies multi‑boiler installation and commissioning in domestic or light‑commercial applications.
