The ABB FCL/S2.6.1.1 Blower Actuator controls two fan banks with up to three speeds via step or changeover relays (2× 3 fan speeds (6 A) + 2 floating aux). A floating output can switch a damper or accessory valve.

Bus-powered MDRC companion to Fan Coil Controllers such as FCC/S1.1.1.1 when fan control is separated from valve/RTC logic. Sister device: FCL/S1.6.1.1.

Key Features

• 2-fold blower control: 2× 3 fan speeds (6 A) + 2 floating aux.
• 6 A relays: Suitable for typical FCU fan motors.
• Floating aux outputs: Damper / valve accessory switching.
• Bus-powered: No auxiliary mains.
• 6 MW MDRC: Compact DIN-rail mounting.
