This parameter window is visible if option Yes has been selected with the parameter Enable direct
operation in Parameter window E, F, G: Fan (Multi-level), p. 124.
Enable communication object
"Switch speed x" 1-bit
Options:
Yes
No
 Yes: Three 1-bit communication objects Speed 1, Speed 2 and Speed 3 are enabled.
The product receives a setting telegram via these communication objects.
Telegram
value:
1 = Fan speed x is switched on
0 = Fan speed x is switched off
If several ON/OFF telegrams are received consecutively in a short period of time at various Fan speed
1...3 communication objects, the value last received will be the one used to control the fan. An OFF
telegram to one of the three communication objects Fan speed 1...3 switches the fan off.
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.
