Example: Start-up behavior of a three-speed fan
The illustration shows the reaction in automatic operation with the option Switch on over fan speed
3, if the fan receives the telegram from the OFF state to set Fan speed 1.
* The parameter Minimum dwell period in fan speed in s [0...65,535] in the parameter window Automatic
operation is only active and programmable, if the option Yes has been selected in the Enable automatic
operation parameter. In the parameter window Fan, you can find the parameter Enable automatic operation.
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.
