You can select the necessary application for your process: Standard, HVAC, PID control,
•
Multi-pump (single drive) or Multi-pump (multidrive). The drive automatically makes
some of the necessary settings, which makes the commissioning easy.
Wizards for the first startup and the Fire mode.
•
Wizards for each application: Standard, HVAC, PID control, Multi-pump (single drive) and
•
Multi-pump (multidrive).
The FUNCT button for an easy change between the local and the remote control place.
