Description
Introduction
The ABB FCC/S1.1.1.1 Fan Coil Controller (Product ID: 2CDG110210R0011) is a modular DIN-rail mounted device engineered for precise climate control in KNX (TP) building automation systems. Featuring an integrated room temperature controller, this unit processes field inputs and directly controls climate outputs without requiring an external controller module. This device is part of our KNX system devices range.
Equipped with two electronic outputs for pulse-width modulation (PWM) control of thermoelectric or motor-driven valve drives, the device also provides three relay outputs dedicated to 3-stage fan speed control. Additionally, one relay output is rated to switch auxiliary loads up to 16 A, such as auxiliary heating. Four versatile analog/digital inputs further enable comprehensive monitoring of room status sensors and control elements.
Key Features
- Compatible with KNX (TP) bus systems (ETIM 9: EC001586 – Heating actuator for bus system).
- Provides 5 total outputs (2 electronic PWM outputs and 3 fan relay outputs).
- Includes 4 flexible inputs supporting digital and analog signals (0-10 V / 4-20 mA).
- Auxiliary switching capability on one relay up to 16 A load.
- Compatible with SAR/A or SAF/A analog room control units.
- Supports ABB i-bus Tool for advanced diagnostic functions and simplified commissioning.
- IP20 protection rating for DIN-rail modular distribution board installation.
Benefits
- Integrated Climate Regulation: Built-in room temperature controller regulates outputs directly based on room targets and sensor inputs.
- Flexible Valve Control: Two electronic outputs support pulse-width modulation (PWM) for two thermoelectric or one motor-driven valve drive across heating and cooling circuits.
- Multi-Stage Fan Speed Management: Integrated 3-stage relay outputs deliver structured fan control for standard fan coil units.
- High-Capacity Auxiliary Relay: Features a relay output capable of switching auxiliary heating loads up to 16 A.
- Multi-Functional Sensor Inputs: Four inputs accommodate analog (0-10 V / 4-20 mA) and digital signals for window contacts, dew point sensors, level sensors, temperature sensors, or room control units.
- Integrated Valve Protection: Features built-in special functions for valve protection to maintain valve integrity over long periods of inactivity.
