for pump pressure
 Indication of the adjusted pump pressure stage in the –OFF- mode.
 Indication of the effective pump pressure stage (rotational speed)
after start.
To protect the pump motor, the rotational speed changes with the load
applied, for example, depending on the viscosity of the bath fluid at
different working temperatures.
