Enable communication object
"Fan speed up/down" 1 bit
Options:
no
yes
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 achieved and a further telegram with the value
1 is received, the fan speed will remain as it is.
Important
The forced operation remains valid and is considered.
The parameterised minimum dwell time in the fan speed for automatic
mode is ignored during manual operation. Accordingly, an immediate
reaction to the manual operation is detected.
The delay time with speed switch over remains active to protect the fan.
With multiple manual UP or DOWN switching the target speed will be
increased or reduced by a speed step. This is possible until the maximum or
minimum possible speed is achieved. Further UP or DOWN telegrams are
ignored and not executed.
Each new switching command initiates a new calculation of the target speed.
This means that a target speed changes by switching telegrams until this is
achieved..
