Application tip:

To prevent condensation, the DX cooler has to be stopped earlier than the air handling unit.
To enable the delayed switch-off, set the plant strategy (PSA_PlantModeNordic) parameter STOP-01 = 2 (electric heating or DX cooling) and adjust parameter STOP-02, the delayed switched-off time.
