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.
