ABB FCC/S1.3.1.1 KNX Fan Coil Controller (3 x 0-10 V, MDRC)

Description

Introduction

The ABB FCC/S1.3.1.1 Fan Coil Controller (Product ID: 2CDG110214R0011) is a modular DIN-rail component designed for heating and cooling control in KNX (TP) building automation systems. Engineered specifically for fan coil unit automation, this controller features three continuous 0-10 V analog outputs to manage analog valves, 6-way valve drives, and continuous variable-speed fans with precision. This device is part of our professional KNX AC Controller range.

Equipped with an integrated room temperature controller, the FCC/S1.3.1.1 regulates space conditions without requiring external control units. The device incorporates a high-capacity 16 A relay output for switching auxiliary heating loads and four digital inputs for monitoring room states via window contacts, dew point sensors, temperature sensors, level sensors, or physical control elements such as the SAR/A or SAF/A series. Diagnostics and commissioning are fully supported via the ABB i-bus Tool.

Key Features

• 4 total outputs: 3 x 0-10 V analog outputs and 1 x 16 A relay output.
• 4 digital inputs for room monitoring and room control element integration.
• Native compatibility with KNX (TP) bus systems.
• Integrated Valve Protection functionality.
• IP20 protection degree for modular distribution board installations.
• Support for analog room control units SAR/A (e.g., SAR/A1.0.1-24) and SAF/A.
• Designed without manual operation buttons on the physical housing.

Benefits

• Continuous Analog Output Control: Features 3 x 0-10 V outputs to seamlessly drive two analog valves or one 6-way valve alongside a variable fan.
• Integrated Room Temperature Controller: Onboard controller processes logic directly, reducing overall KNX bus traffic and system complexity.
• High-Capacity Auxiliary Switching: Integrated relay output supports switching loads up to 16 A for electric auxiliary heaters.
• Comprehensive Room Monitoring: Four digital inputs accommodate window contacts, dew point sensors, level sensors, and analog control elements.
• Automated Valve Protection: Includes built-in valve protection functionality to prevent valve seizing during extended periods of inactivity.
• Advanced Diagnostics Support: Fully compatible with the ABB i-bus Tool for fast field testing, software diagnostics, and efficient commissioning.

Catalog Description:	FCC/S1.3.1.1 Fan Coil Controller, 3 x 0-10 V, MDRC
Long Description:	For the control of fan coil units. Via two analog outputs, two analog valves or one 6-way valve drive can be controlled for heating and cooling. For the fan control the devices features an analog output for the control of a continues fan. A relay output switches an additional load of up to 16 A, such as auxiliary heating. Over 4 inputs the room status can be detected and monitored (Use for window contact, dew point sensor, level sensor or temperature sensor). Also it is possible to connect one analog room control unit (SAR/A or SAF/A) to the inputs of the device. The device has an integrated room temperature controller for the control of the room temperature, which can be used directly to control the outputs of the device. The device supports the ABB i-bus Tool for advanced diagnosis and improved commissioning.
