    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 motor- driven or thermal heating and cooling valves. Multi-speed fans with up to three fan speeds can be switched via floating contacts.

    ® ABB i-bus EIB / KNX Application and planning Application and planning Heating, ventilation and air-conditioning control with fan coil units A fan coil unit is connected to a central heating and cooling supply and 3.1.1 Terms generates the required temperature room by room. A room can be heated, cooled and ventilated with a fan coil unit.

  • Page 11: Variants

    The air is heated or cooled at the heat exchangers and thus generates the required room temperature. The fan is driven by a motor. The motor and the valves are regulated by the Fan Coil Controller FC/S 1.1. The condensed water that is generated by the cooling process is collected in a drip tray.

  • Page 17: Toggling Between Automatic And Direct Fan Control

    A fan drive can also be controlled via the EIB / KNX with the Fan Coil Controller. The fan position is calculated by the FC/S 1.1 and then sent to an EIB / KNX switch actuator. The switch actuator automatically switches the fan speed according to the telegram value received.

  • Page 23 ® ABB i-bus EIB / KNX Application and planning Electrothermal valve drives Electrothermal valve drives are adjusted via the heat expansion of a material as a result of a flow of electrical current. Electrothermal valve drives are regulated via two-step control or pulse width modulation (see Chapter 3.5.3).

  • Page 24: Valve Characteristics

    ® ABB i-bus EIB / KNX Application and planning 3.5.2 Valve characteristics The Fan Coil Controller regulates valves with a linear valve characteristic. The valve position is linearly adjusted to the control value. At a control value of 0 %, the valve is closed (i.e. likewise 0 %). At a control value of 100 %, the valve is fully opened (i.e.

  • Page 25: Types Of Control

    ® ABB i-bus EIB / KNX Application and planning A further adaptation of the valve characteristic is carried out via the restriction of the valve control value. Due to this limit, the valve output does not react to the control value in the lower and upper limit ranges.

  • Page 27 ® ABB i-bus EIB / KNX Application and planning With continuous-action control, the most accurate regulation of the tempe- rature can be achieved without considerable overshoots. At the same time, the positioning frequency of the valve drive can be kept at a low level.
