Fan Coil Controller, MDRC
Fan coil units are used for distributed heating and cooling. They are installed in the room and supplied via a central heating and cooling system. The room temperature can be very quickly adapted to individual requirements using this system.
The Fan Coil Controller FC/S 1.1 has two outputs for controlling motordriven or thermal heating and cooling valves. Multi-speed fans with up to three fan speeds can be switched via floating contacts. Two binary inputs are also available for monitoring windows and the formation of condensed water.
The Fan Coil Controller can either be integrated in the building installation system via the KNX or operated independently as an autonomous temperature controller. To do so, the temperature sensor TS/K 1.1 must be connected for recording the actual temperature. An adjustment of the setpoint temperature can be carried out if required using an additionally connected control potentiometer.
The Fan Coil Controller controls motor-driven and thermal heating and cooling valves as well as multi-speed fans via the ABB i-bus® KNX or as a stand-alone device in combination with the temperature sensor TS/K 1.1. There are two binary inputs available for 24 V AC signalling contacts for window and drip tray monitoring. The 24 V AC auxiliary voltage for scanning the binary inputs is made available by the device. The Fan Coil Controller requires a 230 V AC power supply. All the connections are established via screw/plug-in terminals.
