Manual switch condition input

The module has an input for the manual switch condition MSC.

The user can configure two types of manual operator switches:


Depending on the ManSwCond input the PlantMode will take the values as shown in the next table


ManSwCond input value

PlantMode coded signal

0 = off

0 = off

1 = stage 1

5 = extended operation

2 = stage 2

5 = extended operation

3 = auto

value, according to the actual situation

4 = stage 3

5 = extended operation


Extended operation

For extended operation you can connect a pushbutton or a timer to the input "DayExtension" to extend the air handling unit runtime.

If you connect a push-button, you can set the extended operation period with the parameter DEX-01

If you connect an external timer switch, you should set DEX-01 to the value „0“.


As long as the input "DayExtension" is true (= 1) the output "PlantMode" will have a value of “5”, the same value as for the manual switch of a wall module.
