ABB FCC/S1.2.1.1 KNX AC Controller

Description

Introduction

The ABB FCC/S1.2.1.1 is a dedicated KNX AC Controller engineered for the efficient control of fan coil units in automated building management systems. Outfitted with two analog outputs, the controller can manage either two analog valves or a single 6-way valve drive to facilitate precise heating and cooling operations.

Designed to meet versatile room automation requirements, the device features three relay outputs for multi-speed fan control alongside a high-capacity relay output that switches additional loads up to 10 A, such as auxiliary electric heating. Four status inputs allow continuous monitoring of room parameters—including window contacts, dew point, fluid level, or temperature—and allow connection to an analog room control unit (SAR/A or SAF/A). Integrated room temperature control logic and compatibility with the ABB i-bus Tool streamline commissioning and diagnostic routines.

Key Features

• 2 Analog Outputs: Configurable for controlling two analog valves or one 6-way valve drive for heating and cooling.
• 3 Relay Outputs: Optimized specifically for fan coil fan speed management.
• 10 A Auxiliary Relay: High-capacity relay output designed for auxiliary heating or external electrical loads.
• 4 Multi-Purpose Inputs: Accepts inputs from window contacts, dew point sensors, level sensors, or temperature sensors.
• Integrated Temperature Controller: Built-in logic capable of controlling device outputs directly based on room temperature demands.
• SAR/A & SAF/A Compatibility: Direct input support for connecting one analog room control unit.
• ABB i-bus Tool Diagnostics: Facilitates advanced system testing and fast field commissioning.

Benefits

• Integrated Room Climate Control: Contains an embedded room temperature controller that directly manages system outputs for seamless HVAC automation.
• Flexible Valve Control: Two analog outputs support configuration for two analog valves or one 6-way valve drive across heating and cooling circuits.
• Dedicated High-Load Relay: Includes a 10 A relay output specifically suited for switching auxiliary heating or supplementary electric loads.
• Versatile Sensor Integration: Equipped with four inputs for real-time monitoring of window status, dew point sensors, fluid levels, or ambient temperature.
• Analog Room Unit Support: Interfaces directly with ABB SAR/A or SAF/A analog room control units via the onboard inputs.
• Advanced Software Support: Fully compatible with the ABB i-bus Tool for simplified commissioning, parameter setting, and fault diagnosis.
• Accurate BOQ Compliance: Ordering exact SKU FCC/S1.2.1.1 guarantees accurate technical specification alignment for commercial KNX projects.
