Application tip

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