6.4.4 - 1 Byte Value
At the dire t ode ia „ B te Value the e t step is dire tl se t ia the B te o u i atio
object, The value 1 sets the fan into step 1, the value 2 sets the fan into step 2 and so on. Values
above the maximum fan step will be ignored.
The following table shows the communication object:

6.5 State
Three different state functions are available, which can be activated to the same time. The following
settings are valid for all state functions:
Step for status
For the state-functions as well the current step as the target step can be used. If the current step is
selected, the state shows always the actual step. Because of the times for changeover-delay,
minimum time of each time, etc., a delay between feedback and state function can occur. If the
target step is used for the state, the user becomes a direct feedback after controlling but a gap
between current and controlled step can occur. The following parameter sets the step for the state:

Cascading
Every state function can be cascaded. If cascading is activated for a function, an additional object is
shown for this state. This object must be connected with the output object of the prior FanCoil
actuator. The FanCoil actuator evaluates the input and its own state and sends the larger value to its
output object. For example: The input has a control value of 50% but the own control value is only
10%, so the output state of the actuator will show a control value of 50%. The following figure shows
this fu tio for the state fu tio a i u o trol alue :
