The ABB Stotz S&J Fan Coil Controller FCC/S1.1.2.1 is designed for controlling fan coil units or fan convectors. It can control two thermoelectric valve actuators or a motor-driven valve actuator for heating or cooling via two electronic outputs. For fan control, the device has three relay outputs. One relay output can switch an additional load of up to 16 A, such as an electric auxiliary heater. The room status can be captured and monitored through 4 inputs (usable for window contacts, dew point sensors, level sensors, or temperature sensors). Additionally, it is possible to connect an analog room control device (SAR/A or SAF/A) to the device's inputs. To regulate the room temperature, the device features an integrated room temperature controller, which can be used directly to control the device's outputs. The FCC/S 1.1.2.1 has an easy-to-use local interface. For advanced diagnostic functions and improved commissioning, the ABB i-bus tool can be utilized.
