The following functions are available:
Additional output
For control of auxiliary electrical heating, e.g. in the winter

summer transition
phase.
Fan
A three-speed fan is controlled alternately with a two-way connection or with speed
switching.
FCA/S 1.1.x.2: electronic
Valve drives are controlled. Control occurs via PWM or 3-point. The outputs are
protected against short circuit.
FCA/S 1.2.x.2: analog
Valve drives are controlled. Control occurs via an analog control signal of 0...10 V.
The outputs are protected against short circuit.
Inputs
There are four inputs available. These are used to monitor or connect the window
contact, condensation (dew point), detectors or temperature sensors, for example.
The 6 A outputs are available for Fan Coil applications.
Attention
Improper switching will destroy the fan motors.
Follow the technical data for the fan, e.g. speed or switching function.
For further information see: Parameter window E, F, G: Fan (Multi-level) , p. 124.
The Fan Coil Actuator features a relay in each output, which is mechanically independent of the other
outputs. Switching noises cannot be avoided due to the mechanical nature of the design.
The installation location of the Fan Coil Actuator can either be centrally in an electrical distribution board,
or distributed in a Fan Coil unit. Usually, the Fan Coil Actuator is used in conjunction with a room
thermostat for an individual room temperature control system. The room thermostat sends a control
variable which is used to control the fan stages via the Fan Coil Actuator.
