Logic of the
stage switching
The following illustration indicates the logic of a switchover stage for
a Room Master 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.
