Enviro-tec Fan Coil Relay Board FRBii Replacement Kit ECM HVAC Control Module

The Enviro-tec Fan Coil Relay Board FRBII Replacement Kit line gives you a direct way to service or upgrade the fan motor controls in Enviro-tec fan coil and blower coil units. These HVAC control modules, also called fan coil relay boards (FCRB) or fan relay boards, manage fan motor operation. They are used in repair and retrofit work on commercial air handling equipment.

Key Features:

• FRBII (second-generation) fan coil relay board design for dependable control of fan motor operation
• Available in ECM (electronically commutated motor) configurations for efficient, quiet fan operation
• Multi-speed control for flexible airflow management
• Built to Enviro-tec specifications as a replacement or retrofit for compatible fan coil control systems
• Supplied as a replacement kit to simplify repair and motor control upgrades

ECM motor control generally offers lower energy consumption and quieter running than traditional PSC motor controls. That makes these kits a good fit for restoring a failed control board or modernizing an existing fan coil unit. Choose the child option that matches your unit's voltage and motor type.
