Planning and application
The following illustration indicates the logic of a switchover speed for
a Fan Coil Actuator in dependence on the control values and the
parameterised threshold values and hysteresis.
The diagram relates to a three speed fan without parameterised fan
limitations. The fan limitations are only relevant after the fan speed has been
determined and do not change the flow chart.
