Both current output frequency and actual value are
shown.
• By pressing ▲ or ▼ in this menu, the internal controller of the HYDROVAR will be shut
off and the inverter changes to manual mode.
• With the ▲ and ▼ buttons any constant speed can be set without influence of the
actual value of the control signal!
• If this value becomes 0.00 Hz the HYDROVAR stops.
• As soon as the window will be left by pressing ◄ or ►, the HYDROVAR restart normal
mode.

normal
Regulation mode
Possible settings: normal, invers
Normal: Speed is increased with falling actual value signals. (e.g.: Control at constant
output pressure)
Inverse: Speed is reduced with falling actual value signal. (e.g.: Control at constant suction
pressure or at constant level on the suction side)
