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 signaled 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. he 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
