Speed Levels

This setting allows you to select the fan speed parameters. You can choose from three options:

• level 1 – only one constant speed and OFF

• level 2 – two speed levels and OFF

• level 3 – three speed levels and OFF

You can select 2 formats for 1-byte fan speed object:

• 1-byte number between 0 and 255

• percentage value 0 – 100 %

The value you set as the output value for each speed is shown on the display via Fan speed, status object.

In ETS, practical values are set as default. You can use them or change them later as needed.

If you enable the 1-bit object function for fan speed, the 1-bit objects of each fan speed appear in the ETS settings.

The fan turns off when all the objects are "0".

Example:

The fan coil actuator receives a telegram from the local thermostat and switches the fan to speed 3.

If you link each 1-bit fan speed object to the respective 1-bit fan speed status feedback object of another device, all the linked devices then display fan speed 3 icons on their LCD.

1-bit object for fan speed off function allows you to turn the fan speed on and off via a 1-bit object. A value of “0” switches off the fan.
