Fan speed on bus voltage recovery


Unchanged: The fan's speeds remain unchanged.

OFF: The fan is switched off.

1, 2 or 3: The fan switches to fan speed 1, 2 or 3.
Attention
The device is supplied ex-works with a default setting (factory default). This ensures that the fan setting
is switched off when the bus voltage is applied to the relay for the first time. Thus, damage to the device
due to unintentional switch on during transport, e.g. due to vibration, is avoided.
It is advisable to apply a bus voltage before connecting the fan in order to assign it a defined switch
state. This eliminates the possibility of an incorrect contact setting destroying the fan.
