Planning and application

In this section you will find a description of different types of fans, blowers
and fan coil controls. Here also are some tips and application examples are
described for practical use of the device.
The Fan Coil Actuator FCA/S 1.1M controls single-phase fans, blowers or
fan coil units. Three speed single phase fans with step or changeover control
are possible.
Special fan properties such as switchover pauses, dwell times and a start-up
phase can be parameterised. Up to two input variables for heating and
cooling signals, for example, for a thermostat are available. As output
variables, the Fan Coil Actuators generate up to two valve communication
objects, which they can use to control the valves in a heating or cooling
circuit.
The separate fan and valve parameterisation in the FCA/S provides a
maximum in flexibility and very many combination possibilities for various
applications in the heating, ventilation and air-conditioning (HVAC) field.
Fan Coil unit is a term used for a valve convector or blower convection unit.
The Fan Coil unit is connected to a central heating and cooling water supply
and generates the desired temperature for the room.
A room can be heated, cooled and ventilated using a Fan Coil unit.
