Enable communication object
"Fan speed up/down" 1-bit
Options:
Yes
No
 Yes: A 1 bit Fan speed up/down communication object is enabled.
Telegram
value:
1 = A fan speed is switched UP
0 = A fan speed is switched DOWN
If the maximum fan speed is reached and a further telegram with the value 1 is received, the speed will
remain as it is.
Important
Forced operation remains valid and is taken into account.
The parameterized minimum fan speed dwell time for automatic control is ignored during manual
operation. Accordingly, an immediate reaction to manual operation is detected.
The delay time with speed switchover remains active to protect the fan.
With multiple manual UP or DOWN switching, the required speed will be increased or reduced by a speed
step. This is feasible until the maximum or minimum possible speed is reached. Further UP or DOWN
telegrams are ignored and not executed. Each new switching telegram initiates a new calculation of the
target speed. This means that the target speed can be changed by switching telegrams until the target
speed is achieved.

Dependent parameter:
Options:
DPT 5.001
DPT 5.010
 DPT 5.001: The 1-byte communication object Switch speed (in percent) is enabled.
 DPT 5.010: The 1-byte communication object Switch speed (counting pulse) is enabled.
With this parameter the DPT used to switch the fan speed is set.
