FAN COIL WITH CONTINUOUS SPEED CONTROL
The operating principle is similar to that of the fan coil with ON-OFF speed control, but with
the difference that there are no independent communication objects for managing the
individual speeds - just one 1-byte object.
The figures below refer to the control of the speeds of a fan coil with three operating stages
for heating and cooling. The charts show that each stage has a hysteresis cycle, and each
speed is associated with two thresholds that determine the sending of the associated value.
