Fan Coil

If fan coil is selected under "control types", the control values are output in the same way as described at continuous
controllers.
A fan coil also has the option of controlling fan stages using a 1-byte or three 1-bit communication objects with a
fan coil actuator.
Switching fan stages will heat or cool a room faster.
The fan stage that is to be enabled at which control value is defined on a separate tab, "fan coil heating" or "fan coil
cooling". Note that the threshold values must not overlap, i.e. the stage 1 threshold value must always be less that
the stage 2 threshold value, which in turn must be less than the stage 3 threshold value.
