Description
The Trane BRD4355 Display Board is a control interface component used in systems for operational monitoring and diagnostics. It is installed in air handling units and rooftop equipment to present system conduction, fault codes, and basic control output to technicians during operation. In HVAC systems, it operates as the primary display layer between internal control electronics and service personnel in commercial and industrial constructions. It supports maintenance activities by enabling quick interpretation of system conditions without direct access to the main control board. It is used in routine servicing and troubleshooting of equipment.
