For controlling fan coil units or fan convectors. Two analog valve drives or a 6-way valve drive for heating or cooling can be controlled via two analog outputs. The device has an analog output for fan control. A relay output switches an additional load of up to 16 A, such as an additional electric heater. The room status can be recorded and monitored via 4 inputs (can be used for window contact, dew point sensor, level sensor or temperature sensor). It is also possible to connect an analog room control unit (SAR/A or SAF/A) to the device's inputs. To regulate the room temperature, the device has an integrated room temperature controller, which can be used directly to control the device's outputs. The FCC/S 1.3.2.1 has an easy-to-use local control. The ABB i-bus tool can be used for extended diagnostic functions and improved commissioning.
