Fan speed up/down
The communication object is enabled if in parameter window Fan the parameter Enable
direct operation and Enable communication object "Fan speed up/down" 1 bit are selected
with option yes.
With this communication object the fan can be switched one fan speed further up or down
via a 1 bit telegram. Switching (UP/DOWN) is determined by the telegram value.
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.
The parameterised limitations are considered here. Further UP or DOWN telegrams are
ignored and not executed. Each new switching telegram initiates a new calculation of the
target speed.
Telegram value:
0 = switch fan speed DOWN
1 = switch fan speed UP

Status fan ON/OFF
The communication object is enabled if in parameter window Status messages the
parameter Enable communication object "Status Fan ON/OFF" 1 bit has been selected with
the option yes.
The communication object receives the communication object value 1 (ON), if at least one
fan speed is not equal to zero (OFF). The value of the communication object is sent if not
equal to zero. This communication object thus defines the status of the fan, whether it is
switched on or off and the target speed is also indicated.
Telegram value:
0 = OFF
1 = ON
Note
Some fans require an ON telegram before you set a fan speed. Using the
communication object Status fan ON/OFF, the fan can for example,
be switched on centrally with a switch actuator via the main switch
