To avoid tank deposits, particularly where liquids are involved, it is possible to exit the
hibernation mode after an adjustable time (p2396) has expired and switch to normal operation.
The settings required for the respective variant can be found in the following tables.
Interaction of the function with the cascade control
It is not possible to activate the hibernation mode as long as a motor is directly operated from
the line supply using the cascade control function.
Activating the hibernation mode with setpoint input via the internal technology controller
With this operating mode you have to set the technology controller as the setpoint source
(p2200) and use the output of the technology controller as the main setpoint (p2251). The boost
can be deactivated.
