ISM2 Solar Module for ZWB/ZBR is a dedicated solar‑integration control module that provides the hydraulic and control interface to link solar‑thermal collectors with Bosch ZWB and ZBR series condensing boilers, simplifying coordinated heat management for domestic hot water and space‑heating circuits. Intended for professional installations, the ISM2 streamlines commissioning and safe handover between solar and boiler sources. I could not locate Bosch North America part number 7719003527; ISM2 is documented in Bosch WebETK under article 7719002741. (bosch-homecomfort.com)
