Overview

The application Fan Coil Actuator PWM/2 is available for the Fan Coil Actuator FCA/S 1.1.1.2.
The application Fan Coil Actuator 0-10V/2 is available for the Fan Coil Actuator FCA/S 1.2.1.2.
The application Fan Coil Actuator PWM M/2 is available for the Fan Coil Actuator FCA/S 1.1.2.2.
The application Fan Coil Actuator 0-10V M2 is available for the Fan Coil Actuator FCA/S 1.2.2.2.
Programming requires the ETS.
For use of the i-bus
The following functions are available:
Additional output
Fan
FCA/S 1.1.x.2: electronic
FCA/S 1.2.x.2: analog
Inputs
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:
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.

Tool, see: Integration in the i-bus
For control of auxiliary electrical heating, e.g. in the winter  summer transition
phase.
A three-speed fan is controlled alternately with a two-way connection or with speed
switching.
Valve drives are controlled. Control occurs via PWM or 3-point. The outputs are
protected against short circuit.
Valve drives are controlled. Control occurs via an analog control signal of 0...10 V.
The outputs are protected against short circuit.
There are four inputs available. These are used to monitor or connect the window
contact, condensation (dew point), detectors or temperature sensors, for example.
