The LOCHINVAR L100277940 is a connection board designed to manage and route electrical signals within compatible heating equipment. Connection boards serve as the central wiring hub for control circuits, linking sensors, switches, and control modules so the system can operate as intended. This component is typically installed by licensed HVAC technicians or plumbers during service or equipment repair. Its function is critical to reliable system communication and safe operation of the heating appliance it supports.
This connection board is suited for use in commercial or residential heating applications where LOCHINVAR equipment is installed. It is typically encountered during board-level diagnostics, full control system servicing, or component replacement following electrical fault isolation. Installers should verify the part number against the unit's wiring diagram before installation to confirm fitment.
Designed as an OEM-style replacement connection board for LOCHINVAR heating equipment. No specific compatible model numbers were provided in the product data.
Installation should be performed by a licensed HVAC technician or qualified service professional. Before servicing, shut off all electrical power to the unit at the disconnect switch or breaker panel. Handle the board carefully to avoid damage to connectors or traces, and transfer all wiring connections methodically using the unit's wiring diagram as a reference. Work should comply with applicable local electrical codes and the manufacturer's service documentation.
