Number
Name
Object function
Data type
20
Fan coil step status
Input / output
2-byte floating point
value
Using the "Fan coil step status" object, the room temperature controller receives the current fan
speed level of the fan coil actuator.
10.3.22 Fan speed level 1
Number
Name
Object function
Data type
21
Fan speed level 1
Output
Switching
This 1-bit communication object is used to output the active status (1) of the fan speed level,
while the other fan speed levels are deactivated (0), depending on the parameter setting. If the
fan speed level is inactive, the object has a value of (0).

Number
Name
Object function
Data type
23
Fan speed level 3
Output
Switching
This 1-bit communication object is used to output the active status (1) of the fan speed level,
while the other fan speed levels are deactivated (0), depending on the parameter setting. If the
fan speed level is inactive, the object has a value of (0).
10.3.25 Fan speed level 4
Number
Name
Object function
Data type
24
Fan speed level 4
Output
Switching
This 1-bit communication object is used to output the active status (1) of the fan speed level,
while the other fan speed levels are deactivated (0), depending on the parameter setting. If the
fan speed level is inactive, the object has a value of (0).
