6.1.11 Parameter window "FanCoil general"

Number of fan levels
Options:
- 1 level
- 2 levels
- 3 levels
The parameter "Number of fan levels" allows you to specify the number of fan stages that should be controlled for a
fan coil actuator. You can select from one, two or three stages. The ambient temperature controller always provides a
1-byte communication object (see object: "Send manual fan level" has the following coding) and also provides exactly
as many 1-bit communication objects as the number of fan stages selected. Most importantly, the number selected
must match the actual number of fan stages. An actuator is therefore actuated either by the 1-byte communication
object or the 1-bit communication object.
Manual operation of the fan stage is signalled to the actuator via
Options:
- Object "Automatic ON/OFF..."
- Object "Manual ON/OFF..."
This specifies which object sends the information to the actuator or whether the fan stage is being manually operated
by the user. The only difference between the objects is the coding.
"Automatic ON/OFF" = 1, if manual operation is not enabled
"Manual ON/OFF" = 1, if manual operation is not enabled
Object manual fan stage send has the following code
Options
- 1-Byte object as constant value 0-100%
- 1-Byte object as counting value 0-3
- 1-Bit Values
If the user has made a manual fan stage switch, it can be sent to the KNX.
