Replacement & Compatibility Note
Before ordering or replacing an existing unit, verify SMU1-1, revision number, power-terminal arrangement, connectors, firmware/configuration, and the specific VISTA Automation system. A visually similar STEIN SOHN module should not be treated as a direct replacement without confirming system compatibility.
