ABB i-bus® KNX
Heating, Ventilation and Air Conditioning

Fan Coil Controller, 2 x PWM, 3-stage, MDRC
For the control of fan coil units. Via two electronic outputs, two thermoelectric or one mo-
tor-driven valve drive can be controlled for heating and cooling. For the fan control the de-
vices features three relay outputs. 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.
FCC/S 1.1.1.1 The device has an integrated room temperature controller for the control of the room tem-
perature, which can be used directly to control the outputs of the device. The FCC/S 1.1.2.1
features an easy to use manual operation.
Both devices support the ABB i-bus® Tool for advanced diagnosis and improved commis-
sioning.
