5.4.5 Enable use of Text object for Fan Speed

This parameter shows/hides the Status_ Fan Speed Text communication object.

o If set to “no” the object will not be shown.

o If set to “yes” the Status_ Fan Speed Text object will appear.

Up-Down vanes configuration dialog

All the parameters in this section are related with the Vane Up-Down properties and communication objects.

5.5.1 DPT object type for Vane Up-Down

With this parameter is possible to change de DPT for the Control_ Vane Up-Down and Status_ Vane Up-Down

byte-type communication objects. Datapoints Scaling (DPT_5.001) and Enumerated (DPT_5.010) can be

selected.

o When “Enumerated [DPT 5.010]” is selected, Control_ Vane Up-Down and Status_ Vane Up-Down

communication objects for this DPT will appear.

To choose a vane position, values from “1” to “N” can be sent to the Control_ object. Each value will

correspond to the position (i.e. Value “3” = Position 3).

The Status_ object will always return the value for the vane position selected.

Important: If a “0” value is sent to the Control_ object, the Position 1 will be selected. If a value bigger

than “N” is sent to the Control_ object, then the Position N will be selected.

o When “Scaling [DPT 5.001]” is selected, Control_ Vane Up-Down and Status_ Vane Up-Down

communication objects for this DPT will appear.

The formula used to calculate the value to be set in the Control object is ‘100*(n+0,5)/N %’, where n is the

current fan speed and N the maximum number of fan speeds.

On the other hand, the formula to calculate the status to be read according to the current value is ‘100*n/N’,

where n is the current fan speed and N the maximum number of fan speeds.

Check the example with 5 positions:

When a value between 0% and 29% is sent to the Control_ object the first vane position will be selected.
